4L60E VS 4L65E... What’s so different about these two units?

good morning this is richard back at you today we've got a 99 chevy pickup step side uh the customer had it rebuilt here about four weeks ago uh from a shop here in town i'm not going to mention any names or anything like that he said it's never worked right since uh he's fixing a lot of town and he wanted to pull it out and checked out no matter what so we went ahead and got it out uh visibly it's got this custom paint job on this torque converter here you can tell that's been painted it doesn't look it looks like a factory jeep almost looks like they went and got some paint to match the truck yeah the trucks actually oh yeah they did oh my gosh yeah they just painted it and put it back in wow that's really rough yeah they didn't even sand it so it definitely got a used converter when we got it out uh we noticed the snap ring was fixing to be blown out of the servo right here just barely hanging on i'm shocked it didn't blow it out couple more shifts you happened it was coming so wow i'll take that out really quick just to get it out might be able to go back in our um r r video and see that now we do get a lot of these uh we see them when we take them out they're bent like that a lot of people like to do that and put them in well believe it or not when you put that in like that that makes it capable of coming out so never do that just leave it straight just like that make sure it's good and round and then put it in there like that never bend it but we do see it like that a lot that's another now we're going to look at all the bushings and everything on this train as we take it apart because the customer really wants to know what he paid for so this is a factory gm bushing uh to me the bushing doesn't seem to be uh wasn't replaced period i mean that's a factory gm bushing so i thought you wouldn't replace it the rear seal did look new i already took it out and looked at it it did look new there in that respect retail housing o-ring feels a little firm for that period of time now a lot of people don't even know this seal exists right here there's a seal in here and this is called your yoke seal uh it keeps fluid from coming out the little weep hole in the back of the yoke this seal wasn't replaced neither i can tell it's already flattened all the way around it's not even round no more on the edges here i don't know if you can see that yep sure can you see how it's flat [Music] so this was quite leaking this is really brittle it almost breaks if i pulled on it and that's pretty loose and definitely pull off now we're looking for anything that's messed up any seal cut damage or anything like that now they did put a corvette servo in this thing i did not come out with it this looks like original seal too if it was a new seal uh matter what if it was too much older my total however long right they would still look brand new no matter how you look at it you look at these seals right here i mean there's just no more color left to them you can see a little bit of blue maybe a little stain of red but two months to take all that color away there's no way these are all original seals corvette servo is probably new but we need to take it apart check for where in here because these do wear really bad so you want to check that we'll check and see we're not even sure if we'll put another corvette servo back in it because our wide band and the z pack we put in there uh is going to firm up the shifts no matter now what so much wow i mean these trains when we clean them i mean they're spotless you could eat uh put a pouring of some milk and some cereal and heat out of it if we had that thing he's not gonna lie he'll be that clean people have wanted to see how we clean our parts i'll do a walk through one day maybe show you how to clean a part or two now you do have an o-ring right here it's your lock-up o-ring um hard to tell you know it's flat so it's really hard to tell if it's nude it's still colored good now this is what a new one looks like i already have everything laid out for this unit over here that we're going to be putting in it so we'll show you in just a second when we get a tour down but gives you an idea what that seal color looks like uh it looks like me they got enough grease on the front seal i don't think it's um i mean not lubricated i mean that's kind of one sand storm that still would have been wiped out i mean wow yeah so let me see if i get all these not bad a lot of times there are times uh it does take a special sock at the 50s too we get them off the macko tool truck snap on stuff like that carries them but it does take a special socket to fit in there you want to make sure it's down in there deep too you ever strip that out and have to chisel that bolt out to get it out you're gonna be crying ah i see here you know they might have changed the o-ring or it's hard to tell but we would have double sealed these no matter hey look at it that way no food leaks you wouldn't believe how much pressure is actually on these bolts right here through here so you really want to double seal them sorry this thing's got a little bit of a smell to it it's got a little bit of burntness look in the pan and we do have a deep pan filter and that is the right filter for the pan now we did round up all of our filters uh to do a filter video so we're going to be doing that next after this training so look forward to that the 3-2 downshift solenoid your pwm solenoid right here now we're going to look at the valve body and see if they did any modifications to that valve right there because we definitely like to do uh some there oh almost dropped you let me grab a tent yep sorry now this is your main lock-up solenoid right here this physically is what uh triggers the lock-up valve in the pump uh to bring lock up on uh you can change these out you can cut this and uh splice the new one in you always want to check it with power when you clean it make sure it rattles you'll hear it rattle after you clean it huh now this here's your p or your pillar switch right here this switch here tells the computer that the made the shift uh these are your physical shift solenoids uh this is your epc solenoid right here they make an early and late the late model will have the connector on the side right here these three bolts right here are longer for your pillow switch then your ten millimeters here and then you have your three eight millimeter all right these three eight millimeter right here you can see the difference there you can see the difference there these here your body these eight millimeter here in this little l these little bit longer ones go on your pillow switch um you can see this reclaimed fluid comes in here and pushes on these little switches they click kind of hard to hear it buddy i can feel it can you see it down here here here and here once the makes a shift it pushes on his computer sees it says hey i'm happy goes to the next one pushes on this sees it makes i'm happy so that's how that basically works it's crazy it's like it was washing itself as this clean fluid was going through the thing yeah i mean it makes a big difference on how you clean these uh the fluid or the dirt gets into the pores of the metal and stuff like that you can see just by touching it you know rubbing it and you see the gray come off of it and that's if you don't get that off there when you put it back together it's coming off with new fluid all right you can just tell the valve body's really dirty still going here look and see if they did anything to this valve right here see they didn't do anything to this valve right here it's still pulse width modulating uh we'll go in here and block this valve right here where it doesn't work at all and make it feel like a shift that's the best thing you can do to this training is blocking this valve uh from the early model to the very latest ones that they make we block every one of these and it just makes converter life uh 10 times longer so we need to do a video on this we're going to show you how to do it here pretty soon probably after the filter video and show you how to do this that way you don't have to spend the money doing that if you overhaul it yourself so i got all your check balls here screwdriver must be a little bit magnetic uh they do have the right gasket on it they've got a round hose square hole gasket and we talked about that before if you put a round hole round hole gasket you've caused a problem in your lockup system right here uh we had a customer or not a customer but a a gentleman get a hold of me on youtube and asked me that question if uh he put the wrong gaskets on it would it cause a lockup issue uh and yes it will uh it's right over that your lock up system right here and you put the wrong gaskets on so and once it throws the code uh it goes into hard shifting because it raises line pressure so just try not to put the wrong gaskets on yes just remember that round nose square hole and it's hard to make a mistake now if you get into some of the later versions you really want to match you know the 2016 stuff like that now we replaced all these pistons and stuff like that um it doesn't look like to me it looks like probably just a factory pistol i'll show you what ours looks like let's see if it's any different so it is an upgraded piston it's got more than two thousand or two months under a month or whatever but uh it is an upgraded piston but we will go in here and uh modify this and make this a piston stroke half the stroke of this piston instead of it going all the way to the bottom we will make it only go about halfway that way your second gear shift is so much shorter makes it really nice and it looks like they might have put a new o-ring on it but uh they didn't even seal it very good it kind of just fell out it had a little bit of condensation in here looks like a little bit of oil uh that could cause some issues too so we're going to put a whole new wiring harness and stuff in there that way we don't have any issues with it right off the bat because we like to put them in and not have to worry about them what the heck did they do here never seen that before that's really stuck on there good almost like it had a little bit of water in it maybe or something that guys get to stick that hard to that to the case i've never seen it but i was about to say did they glue it on there yeah i yeah that's good uh no modification was done to the 3-4 accumulator they just stuck in piston in there doesn't seem to be wore out but we'll block this anyway we'll throw the spring away where we don't use it yeah it's crazy thirteen kind of work they did here that does look like it has new rings you don't very seldom see a scarf cut ring on this uh stator for the reverse drum normally it's a solid ring so i really don't know where they got that or maybe it's a shift kit or something i haven't seen any signs of a shift kit yet we just have to look so that looks possibly like a new bushing the uh factory bushing is like a babbit looking bushing kind of like the tail housing bushing i was showing you a minute ago same way here uh that's an aftermarket bushing it's brass the original ones are babbitt they will look like your tail house is fishing it'll be like look like that for that bushing and that bushing there so that's how i can tell that these have been replaced stator looks good a little bit of staining nowhere there does have a 13 vane pump not new uh that's more than uh a few weeks away or there you can actually feel the lip oh yeah right there where if you get a a new one see they're just pretty black all the way or if you look at this one you can really see the where difference in them yeah that's more than a month yeah that's funny yeah let's put in there already had that wear [Music] now these are just steel rings here the rings we're going back with are stainless they're more of a higher rpm ring they just a lot stouter all the way around so now see this pump slide right here uh it is a dual spring early style but if you look at this pump slide they let me wipe this off you can really see the wear start from here to about right here you see that you can there's a lip right here there's a lip right here it's kind of crazy it won't wear the pump but it'll wear this state this slide right here so we put a new one in in the kit that we use uh also you can get in here and you can see where the blueing is starting to wear off this slide already can you see that keep turning [Music] you can see where the paddles are actually starting to get hot oh yep in the very very center of it huh so also you want to look here make sure there's nowhere on this pin and actually there's some pretty good wear on this pen right here can you see that right there that lip yeah you can actually i'm gonna see the lip in the camera well that right there that where right there will let this slide set crooked that's what maintains the stability of it right there so you always got to check that replace that slide also gets you a little slide spring a lot of people don't know it's there they turn it over and it falls out it sits in there just like that when it sits down in there so pump looks really good nowhere just staining what about that bushing let's see actually no no this actually didn't put a new pump bushing in it um you can see here where the motors war now the crankshaft's sitting low you can see how the brass is showing from here to about right here you can see and then the rest of bushing uh doesn't look like it's ever been touched this is the top of the bushing so when you turn this around that tells me that the crankshaft is setting low in the motor so it needs bearings and stuff putting the motor to this crankshaft backed up we'll put the crank back in the hub back in the center so that we just uh had one here the other day we got another bushing in there on my desk uh the same way we were showing the customer it almost spit it out yeah didn't it it'll grab them after a while grab this bushing uh once it gets all the coating off like it has because this coating right here is real slippery it's a real slimy feeling where this right here is real bitter it's kind of it'll grab your finger and once the converter gets good it grabs it it doesn't spin the pump bushing out start leaking up the front nice info you want to get this band anchor out of here right so that way you can just pull all this whole assembly out so you stayed with thrush washer now you can see here it just has a stock band in it uh it is an aftermarket band [Music] i don't can't tell if it's been as a reline or whatever but it is a new band all right we'll go back with a band uh twice the size of it same material uh but this band really works twice the size what's the size so and also to get in here uh you need to check the flatness from here to here where this band runs if it's bowed inward at all you need to replace this drum uh you can take a flat edge actually i got one here i'll show you almost looks like they buffed it with a buffing yeah it looks like they but you can take this like this and play the flagship flat edge on there and there you go let me show you a flashlight here and shine under it see that right there that's how bold that that drum is right there that drum will not work it's got to be flat all the way across so you need to be checking it it's amazing that that band will try to squeeze that drum yeah these trainings you put boots out and stuff like that that's why we'd like to get a full wide band on there that covers the whole drum that way it's physically squeezing heavy out here too instead of just you don't even touching here come out here it gives it more uh area to grab instead of just bowing it in the middle like that so the drum is coast it does have a big hole drum you want to watch for that they do make a small hole drum too you do not want to put a small hole drum in here remember that he might get money for this rebuild and it's only got like four weeks on it so now this is the reverse clutch uh you can tell that's pretty much an original clutch you can see here what a new clutch looks like a reverse clutch even if i dip this in oil i'll show you it don't look that old you can tell here what a new one looks like even two months away now you can notice here this should show you something while we soak our clutches so you'll see the fluid being absorbed in by on the clutch you can see all these air bubbles around it it's absorbing the fluid in there so we soak all of our clutches and bands before we install them in our units uh that way the works just like it did when it uh like it's been running for 20 30 000 miles i mean the train don't know no different if you put them in dry non-soaked uh it's going to slip bang to all kinds of crazy stuff and you're going to wish you never did it so that's cool it was sitting there bubbling soaking that in it'll suck them in there if i set that clutch over there come back five minutes later it'll be dry because i just flopped it in here for just a minute well we're gonna go back over here there shortly we'll see what she looks like let that work yep now if you notice here too where this reverse clutch starts heating up this forward drum [Music] so you can see it so we'll have to go out here and get a drum uh because there's no way to fix this except to replace the drum once that starts happening uh the clutch this reverse clutch gets on there and it starts doing this so instead of staying steady and spinning perfectly it starts getting wear in there and it starts doing this stuff and and this will get really bad and then the clutch starts getting locked and then you put in reverse the clutch won't slide up and down because it's stuck in this groove right so i always want to check your rings here put new ones on be careful not to cut them you cut them you'll lose third gear you lose forward and you can lose your engine brake clutch uh we had a customer or not a customer but a youtube gentleman called me built his training he lost third gear and uh he cut this ring right here so it's real easy to mistake to make it is so be really careful it is now this tray just has uh your standard clutches and stuff like that in it i will get them all out here it does have the load springs in it uh but they'll just plumb more out i mean these springs ought to stand out about that tall so just because you have a low spring say i got a low spring let's put it in there you better check the depth or the length of these springs because they need to be long because they wear out real easy from heat uh usually this train has been built before so these this three four clutch packs been burned up before so these springs have been hot so these springs are collapsed they put it back together with these used springs uh and here we go again so this is the three four clutch uh it has already burned up again and you can smell it uh you can tell here um they put this back in there as a a worn out piece to start with against this clutch these steels uh they weren't any better we will go back with a z pack right here with our 14 clutch again that we put in there this is a single-sided set uh these are the best things on the market to use let me tell you i don't care if your grandmother's car your daily driver your race car whatever people say i don't put them in your daily driver let me tell you what we put them in every day daily driver these things will last so you just got to make sure you build your right along with them to make it last so and that's what we do here pretty sure you just had a guy come in with like three hundred thousand miles on the 4060 see what the forward plex looks like here now i want to always uh stress myself on this bearing right here uh always check it because uh these are bad about going out and causing wine in park and neutral and you're thinking it's the pump and it's not it's just one little bearing right here so you better check it and it does come apart you can take it apart and check it stuff but it's best check it find another one if you think it's bad you can't damage it too if you don't know what you're doing this bearing right here is my little favorite bearing it never goes out i mean this little bearing right here that will last a lifetime nine years and so many else's i think but uh it never goes out but always check it now this is your forward clutch and uh your engine braking clutch here now i really can't tell if these are new or not these this is a little bit different brand clutch than we use here and i know these here are used so this is this much new that's that clutch and you're sucked in oil and you can see it sucking it up really big come through the air bubbles again yep just sucking that fluid up awesome but uh all these steels need to be replaced i mean it's pretty much uh all this stuff right through here in this beer place yeah you got your forward private family here yeah now they make a good and a bad one of these uh i like the one with this uh gear or ring gear played where you want to call this right here is flush this one still will work fine and last but i do like for the high horsepower ones instead of we'll put the little bit later version in there and get the one that's applied i gave you a general idea what i'm talking about so this is a flush one this is a stepped one the flush ones are a lot better so now this does have an aftermarket sprag in it uh can i tell if it's new i really can't tell um but uh let me get this off here you always want to look for chatter marks and stuff on this inner race just a little bit of staining no no no lips no fields or nothing like that actually it looks really good i'm impressed look here too on this outer race for any type of chattering anything like that looks really good we scotch bright both of these up a new sprag in it grab a good cover and put on there and then you got a really nice system oh i'll just guess this is your sun gear your forward sun gear uh you want to look on both sides of the gear because you have an on and off gas uh you'll get wear on both sides of the gear so on the other yep right there i don't know i put it in backwards probably i wanted to squeeze it real wide and just bend it but right yeah there you go see how they put it on yeah so we have your standard fork uh gear planet here your forward planet i want to just make sure these gears don't wobble check your uh load washers on the end of each gear you want to come in and check right here too this has got some wear right through here this axe have to be replaced these are pretty good ruts right here this bushing right here started wearing so i didn't now anytime we uh get a union here especially a little truck like this that he's gonna be playing with got some stuff done to it we're going to upgrade our uh forward clutch hub right here so what we do is uh we put a roller bearing right here where there used to be a thrush washer right here like that we're putting a roller bearing just like that so even though these things show to be good uh let me see here now that i noticed that the washer style seems to be a little bit stronger should i get this out of here without poking me come on let's danger i hate to do it but i'll put the old spectacles on so i can see this stuff a little bit better sometimes yeah i was looking for your little pocket screwdriver because that definitely looks dangerous don't try this at home with a pick yeah definitely don't try to get it with a little pocket screwdriver normally what but just what we had on hand there we go hey no fingers poked good to go but what you want to do anyway you want to take this out [Music] even if you don't have wear here or you don't have wear here you want to come in here and look here see how this thing's almost stripped yeah so we see this all the time people think oh this feels good this looks good this is good but if you don't know to take this apart it's fixing the strip out right there so we upgrade to this to the roller bearing style uh really big upgrade yeah when they did this style they added a tow haul button to the shifter and that's where you just come from sweet more upgrades yes now this is just a stock shell it's not a hardened shell uh this is probably the original shell that come in the unit because it does have wear on the splines and stuff this nub is bad about breaking off right through here uh we'll put a hardened shell on here with this whole end's been hardened and it just eliminates the wear and stuff on this shell so poor old tranny's been down the road and now the same way this uh lower sun gear you want to look on both sides make sure there's no pitting or anything like that now can you see this right here yeah they have this snap this anti-clutch spring right here how they have that snappering in in between here and here that is where that is supposed to be so when you build this training back you make dang sure you put that right there okay if you put this snap ring over the side of it the snap ring will blow out so you want to make sure that that's not like that yes sir y'all guys write that down just make sure you do it now remember this is was built by another shop here in town too long ago and uh the customer said it's never worked right and he was fixing it quite a town and not even scared to take it so that's why we're going through this for him to make sure he's going to make it and by the looks of it he wasn't going to make it so now here's the low reverse clutch right here that's in the back of the uh this is the way it looks to me is a used clutch too uh the new clutch if you soak it has a totally different color to it so to me that's a used clutch too so i really didn't see much of anything new in here uh it does have the wide sprag in it uh we'll put another one in here you can see how that roller is hanging right there so you just gotta make sure you remember this lip uh if you have to replace this piece always getting one with the same uh depth on that lip right there so look at your planet now this is an aftermarket planet uh gm did not come with this ring on here um so you want to really check these right here i bought like 12 of these aftermarket planets one time and like 10 of them come back and luckily i caught them on my 3 000 mile services i was able to go back in and replace them but the company would not warrant him so you got to be really careful here's your anti-clock spring now if you get in here look they did make a bat at case bushing gm did but it's really hard to tell if that was replaced it's beat up so bad it doesn't look like to me it looks like the original bushing too i'm gonna say with it wasn't so this guy got really chef really bad um we know the shop that does it we've known their work and stuff like that and we do a lot of redos from them and stuff like that so it's just a sad day when people get ripped off and stuff but if you look over here we do have our new clutches uh new pump rotor kit stuff like that seals bushings uh epc cylinder z-pack uh our trans gold boost valve we're gonna be putting in it um our new forward sprag our new low reverse brag uh cumulative pistons stuff like that so uh it's going to be a really nice unit when we get it together excited it soaked up really good it did it almost drowned that one side in places some of them don't soak up as much some of them will soak for 15-20 minutes so that little one starts soaking instantly yeah they do man look at that 727 unit you got built there too looks good we did get our transparent 727 unit built too uh it's got the 48re uh direct drum six clutch we put the steel planted in it and stuff uh transbrake valve body trans brake wire there uh put the 48 red pan in it for him uh we're excited for him it's going to work really nice so we're going to get back to this one get this thing together for him he needs it really bad he's tired of walking i believe uh and getting his truck back so if you don't hit anything give us hard precision transmissions you all have a wonderful this is uh richard back at you today we're working on a 2007 uh chevrolet pickup uh he brought it in for a service and the pan and the fluid is just really black it's got 200 something thousand miles on it so he decided just to go ahead and go through it while he had it in our shop so before we tear this down though you gotta go scribe on our youtube channel before i tear it down one two three i'm just kidding let's get our tour down but he is serious go subscribe yeah it's just got the stock torque converter tmbx you can identify it right here we'll be putting the exact same one right back in it so that is how to identify the gm converters fluid's pretty brown for sure it does real it's kind of like looks real thin like water crazy look in there but this is a 4l65 this is a pretty late version right here i'm telling you i fought it getting it out the was stuck really hard to the motor oh everywhere it was hard some of these things are really hard to get off the back of the motor they just pin so tight to the dowel pins and stuff that you almost break the case now this has just got your standard servo in it we don't see you to expect to see anything unusual in this here it just stepped a lot of wear until it's been hot before it seemed like yeah make sure you get that flush because you ever have to chisel one of these boats out of trouble [Music] bingo baby there it is i like it when gm did this because you can just put so many different belt houses on these things that makes it so universal got your seal retainer look at that retain that ceiling they're really good then i took it over my hand but like i say that's why we always glue these on these do work really good if you glue them on um but just physically set in there then they're kinda we woke up to about two inches of ice and snow this morning just covering the ground i'm really shocked the pan looks really clean this thing must be running really hot to turn the fluid that color could be starting to lose lock up starting to slip it a lot but that's just really really dirty the filter is really dirty too uh just probably lacking some maintenance no got your parking retainer here i turn that thing down call you back call you back this here is uh that was my son actually calling me uh now here's your input speed center that's why they call these the 65s and the 70s too they added a speed sensor down through here and this is the connector you'll notice it'll be the three wire plug over to the right almost smacked him in the face of my elbow gotta get what he gave me one day no i'm just kidding get this off here really quick i turned my phone down and it still was loud that's kind of crazy get that little clip out there this is your pwm solenoid right here a lot of times these little filters fall out see how that turned mm-hmm you just kind of look at them some of them will fall out they fall out just thrown away if you blow them out there or anything like that just get you another one then you got your main lock-up solenoid here ready to clean these up make sure they rattle i always run codes on these before you take them apart uh if you've got a coat for the solenoid to go and replace it if you don't then just clean it make sure it rides because these really don't have a high failure rate huh [Music] so they still got a cover on these on the top but they still get so much trash in here it's hard to believe the switch even works with that much trash but it does you'd think it'd be like self-cleaning where just keep cleaning and cleaning cleaning and never make trash as much pressure goes through this or at least circulate to the bottom yeah to the pan but it doesn't now this here will not have the lock-up valve blocked or anything like that it'd just be a two-piece valve in here with a spring now we will go ahead and block this whether it's a 65 or 70 no matter what we block every one of them and believe me it works so much better i'll make sure all your shift valves and stuff are free especially this one right here this is your one-two accumulator valve there's actually two accumulators for your one-two shift and this is one of them so and this is your second one so this valve actually has to open before it gets fluid to this one so that's how that works got your accumulator here too for your forward engagement you want two shifts solenoids let me show you this here pull that valve out of there like that grab this plastic piston pull it out if it's plastic get rid of it now you can go back to the early ones and get the aluminum piston out of there and put in here i don't know why gm went to a plastic one but you can go get the early design and put it in there retrofit right in there so pretty neat now you notice this thing here doesn't even probably don't have a spring in it it might have a small one in the bottom just to keep the piston from bottoming out see it has that little tiny one in there and what we do is we'll take it still even though this is like that i will go find other springs and put in here and stack this piston to the top they make spacers we can put on this deal to stack this up just even lift the spring up some of your shift kits even make it so you still want to get this piston all the way to the top and touch seal off there i have springs everywhere around here that i can use but you see that we want to get that piston all the way to the top that way it starts applying that band instantly right when it starts touching that piston now if you notice here we got this bonded gasket stuff going on again right here if you notice the gasket's made to the plate it's glued to it don't come off and it's got the screens embedded into the plate so right here they actually added one right here on this one you can see it here you got this one here and this one here here early design you know it's a add-on filter like like these right here they'll pop in here then you have another excuse me that'll i get you took a bath almost then another one will pop in here a different size that's in your kit but these you leave in here we will not grind this gasket off we'll put this gasket right back on some of them have an indention you kind of feel and kind of lock it back in place but these gaskets are so hard that even being tightened down before it didn't indent it i mean it's just really almost as flat like it's never been implied wow so don't try to grind it off and put a gasket on it they do have gaskets that'll come in your kit but you'll end up destroying the plate and then you'll be looking for a plate so same way with this one here we're going to block it all the way to the top again use this piston just get to another and chunk the old spring away and then stack it up like i showed you guys in their other videos you have one check ball right here and then there's no other check balls here actually in this training here there's only one check ball you have to physically put in so it's pretty hard to make a mistake on the check balls but if you left them all out it'd just shift firm or something like that but if you leave that one out in the trough right here if you leave this one out you're in trouble you can leave every one of these balls out but this one yeah if you leave that one out you're in big trouble [Music] that ball there keeps it from going into forward and reverse at the same time so that's what that ball does now you notice you got your hard ring right here for your pump instead of your rubber o-ring somebody's really tough to get out i'm telling you it's so hard all the some of them are hard to get out i just have to work on it a little bit but you can see your sensor right here it goes in the side now we replace every one of these just because even if it doesn't have a code for it you better replace it because if you don't you can have a problem with it and then you're pulling the back apart so one thing i don't like about this they kind of destroyed like i said if i'm building this or if i got it in car i'm gonna put a shift kit in it or something like that this covers the boost valve hole i cannot change the boost valve while it's in the car where all your other versions i can but once they added this they covered it see there it is to take that out to put a 500 boost valve in there you can't do it in the vehicle because this physically covers it now terrible idea but that's what they did to us and that's what we have so there's nothing we can do about it but that just tells you you can't do it unless it's in the vehicle or out of the vehicle pump looks really nice even though this is a brand new a new version and all that type stuff you still want to silicone your silicone right through here that way you don't have no fluid getting into the vent circuit from your pressure side of the pump and here it is right here right through here this is your pressure this is your vent circuit so you want to make sure you put some silicone there and seal it when you put the pump back together and here they went to the single spring looks like a cone on each end instead of square that's how you can identify it i don't know if you could put the dual spring in here and it'd be the same i've never tried or never asked any text or anything like that to see so i just always put it back original pump slide look for a little spring look for your pin anywhere on this because you got anywhere here your slide will run crooked so you want to make sure it's centered with a good pin look for anywhere here starting to see some wear in the bushing area you can see it's starting to shine up right through there a little bit oh yeah crank sitting down sitting down a little bit you don't see it much on these motors it's kind of war all the way around definitely want to check the flywheel and stuff like that too when we get in there we look at the rear main seal cause we check all that stuff before we take them apart wait to see how those stock bands has been really sliding on that drum right there see that's probably where our heat's coming from yeah just after time i mean it just but these are the best bands with the material on from gm but i said we go back with a wide band that just makes it so much superior and you can see here where their band don't cover a quarter of it here a quarter of it here where our band covers the whole distance actually i got one right here i'll just kind of show you give you an idea how much bigger that band is and total cover at all but it's a nine-day difference reverse clutch looks good always make sure your your inner part of your bevel goes towards the steel like that don't put it like that it goes physically like that i get them in here like this and that's not the right way because this is designed to smash once it smashes it plugs this hole right here and pressures up it doesn't have a check ball in this hole they physically use the clutch to come down and flatten this and plug that hole instead of a check ball so if you put it in upside down i don't know if it'll work the same i've never done it but if you look at it it would rub on here say and that's where you'd probably start having problems with your little feed hole right here start smashing or something doing something crazy so it does go like that that's your big hole [Music] now you can see your reluctor right here on your input shaft that your sensor reads in your pump now we did have some of these units come in uh that had this drum in and pump in it with a blank plug in the sensor hole so that tells you they were slowly getting ready to change over they start adding the parts but they haven't changed over yet so that's why we see a few of them coming in here that way but once gm gets going they start switching it all up quick this is going to be a nice training to take apart build because it just hasn't been touched by any delicate hands out there that's a good way of putting it i guess oh three four clutch is just about totally gone that's probably where a lot of our heat's coming from too so this old tranny's got a lot of miles on it the load springs are still kind of tall we'll check them and see if they're as tall as the new ones you got your engine brake clutch your forward clutch now you can start seeing some clutch teeth wear here uh where they've been backing up throwing in drive and coming before they come to stop it'll start knocking these teeth out let me start you can start feeling it actually their teeth are almost half the size of them yeah i don't have them soaking in have to go get some but you can start seeing the wear on the teeth we're starting to come off look at this brac now this is uh the that's crazy they still use this brass brag but they do they they went to a plastic body though for a while and got rid of the the metal body but you notice this is a dual cage like the metal one that we put in there well this is a gm dual cage sprag so gm did start getting a little smarter and started putting them in there and the later versions and helping but they stayed with this brass washer i don't understand why because this outer brass washer always wears like crazy and when it does it don't affect this hub up that much but it wipes out the washer this thing got a big old lip on it right there it'll just lock right in there yep see it locks it in there and this one here just flies perfect nope i think there's no wear on this looks brand new now they're more plumb out wow so the new swag we put in has got metal uh thrust rings on it so it'll be a lot better actually it looked really good here too just some some staining nothing uh nowhere no lips or anything like that if you notice this bag here was turning on both races a lot of them you don't see that a lot of times the spraggle just settle on this one and only spin on this but this one here has actually been spinning here and here you can see where it's been done a lot of times this bag looks brand new like it's never been used or the race i mean so pretty crazy get that thing out there yet dang i still can't get it yet come on now i can't get that out of there you got to get it out before you put it in the washer though you'll never get it out so we do have our roller bearing hub here get my shell out real quick just a stock shell i almost look like jim i'd start heating some of these up a little bit more those look a little bit different color it'd be smart yeah you've got your sun gear here rubs on here we just have that single bushing right there that rubs on here really hard but they hardened this so much you don't see any wear here anymore we used to see tons of wear but you can see now look how much wear we have in there i'm gonna strip it let me get that out to show you i don't know why they didn't harden the whole thing but they hardened this end and not this end where the earlier versions we didn't have no problems with this end it was the other end so it's kind of like how wore out that is if they had to harden that just like they did this we wouldn't have no wearing this piece at all that's why we have to replace every one of these five five six a week i mean every one and we do we have to put whatever because we upgrade uh all of our units to the from the thrust washer styles of this one on every one we do whether it's the 700 4060 or any of the e models so we do hit them all same way the sun gear you need to check for any type of wear on the both sides of the teeth because it when you let on and off the gas it applies at this side this side so you just want to look on both sides of that can you see in here trent see how they have this snap ring right here and this anti-clunk spring right here no they didn't even get it on there from factory yeah it's actually rotting just barely in there see that that needs to be all the way in there by the way it gets past this piece here too it didn't come out because i didn't have it all wrong wrong but they didn't have it in there where i put it of course you got your your band strut right here you don't want to lose so if it don't fall out it's usually stuck in the case right here so but you always want to go get it last thing in there is going to be that little piece right there some of them hang in the case some of them will fall right out so if you leave that out you're just going to hear clunking in the this thing rocking back and forth in the case from park to reverse and it's annoying as heck so don't forget it pop pop pop pop type sound got a nice wide sprag in it now gm did upgrade their sprague assemblies to the big brass ones they were big but they did go with the brass uh cage and stuff like that on their later versions race looks good you want scotch brought that up really good put a new sprag in it i get that in there but i am going to show you something too once i get this apart updated now this is your lower sprag right here low reverse price is what we call it's a manual low clutch and a reverse clutch so that's what that looks like but i wanted to show you man i don't have let me go out here to the trailer and grab a retainer really real quick kind of show you something [Music] since i got you on the tube i just want to show you some other stuff here now this is a real early 700 hub for your lower planet and ring gear this is the later version you see how they cut this off right here that's to guide more oil off the edge right here and get it to that planet gear okay when gm went to the 65s and the 70s and their five pinion planets they went to this one right here you see how that smooth real smooth compared to these that's to get that fluid to that planet every bit of it that's why gm did that it even looks different in the back now all your five pinions will have this this is really the first four pinion unit that i've seen come in here with this here without a five pinion planet so i don't have a i already took it out to the trailer but trash but i had a five pinion in here yes that had a slinger on it uh oh yeah and what they did is if it has that slinger on it these pins are hollow and when they're hollow that slinger's got uh designed to guide oil through that pinhole to get oil onto these right here as fast as they can as much as they can because that was the problem with these is not getting enough oil so they really want to flood it and that's how they did it they just did some technology did it that way so if you can find one of those it will upgrade all the way back so it and it definitely it is a lot better a piece to put in your so this is going to be an enjoyable one to put together not a lot of carnage or anything like that so we'll get this thing put back together you all have a great day
