It’s a Build video

we are back at precision transmissions uh we're gonna be putting this uh 350 back together uh with some pretty uh intel uh information so um watch stay tuned what we got is uh anytime we put a case bushing in the 350 you really want to never use the original driver you always want to come in with something a little bit bigger and go on top of it and put it down in there like that that way the bushing doesn't get put in crooked it's the bushy's not very wide so it's easy to put it in crooked once you put it in with your flush driver like this then you can come in here with your other driver and put the depth in it that way the bushing is straight now what i mean by depth is the bearing that sits on there has a chamfer on it right here you have to put that bearing lower than that chamfer if you don't you're fixing to make a lot of metal and mess up a lot of stuff so let me show you another little thing now we talked about in place setting in play a minute ago uh on the other video and getting the uh ring uh away from the end of the drum which we talked about right here getting that with this sets on there if you shim it too much here that ring gets out on that ledge now we talked about how to shim this thing different ways like right through here on top of this planetary you can put a sham put that in there like that and now you just shimmed it forward and you could take the shim some shim out of here well they also make another way to do it you can buy these if you can find them uh it goes on top of this bearing here like this and this bearing sits down in here like this which moves everything to the top same principle well we don't have a lot of these when we you know we have to buy them and they're hard to get right now so we can shim them multiple different ways so put a little bit of oil on your bearing set it down in there and here like this now this is a roller bearing uh ring gear right here for your uh rear planet they make a three tab washer style too this is a really good style i can race cars roundy round cars or anything like that and also we talked about this bushing right here this is the plastic piece that sits in there normally uh if you take the training part this can fall out and you can lose it real easy so we always go back to the bushing it works a lot better but if you lose that you just all the lube oil is going to fall out right here and this planetary's going to burn up so you have to put something in there so this is our rear planet you want to check all these gears for wobble right here all the way around for wobble look for any pitting anything like that put a new bushing in it make sure your thrush washer good stuff like that we'll go over here and dip it in a little bit of oil get these nice and lubed up now remember this was already put together once and i took it apart to do this video like that now this is where your parking paw when you put it apart that parking paw grabs right here in here and locks this shaft down that goes to your drive shaft but the roller bearing spins so much nicer just put this down in there excuse me let me back up a little bit because we're going to go into really detail on this thing we need to uh know how to check uh clutch clearance in the bottom down here since we upgraded this to the the wide sprag assembly the 4l60 east brag and and support back here the clearance could be a little bit different if you just put the 350 clutches back in new with steels so we're going to set these down in here like this and we're going to check some things like that so we're going to set this clutch down in there but i'm going to show you something when i put this together i used all 350 clutches put it back together my my in play was wrong it was way off so there was no way to physically set it so what we do as builders we've i've been doing 40 years been doing it for a long time we can take and shave these clutches off the back like this put them together because they're already locked together anyway and what i did is i add the thickness of that steel right there to my clearance and that's all i needed so now i can set this down in here like this put this down in here like that i can come in here and reach under my fingers and i can check my end play you can check it down through here and you get it to with air by watching the travel of the piston or you could check it here with your fingers and feel it that way too so [Music] that's how you can do it by like that so we'll put our planetary assembly back down in here these clutches have already been soaked but i'm going to dip them again you always want to soak your clutches for 15-20 minutes and they will just suck the oil right into them that way the it's been working all the time the clutches doesn't know any different all these steels were really good shape all we did was have to buff the gloss off of them and put them back in it saves the customer money and uh all the way around you see how that's set in there like that those two clutches that i buffed are locked together there's no way they're going to move identical okay now we're going to come in here and put our anti-clock spring in that keeps that support from rattling when you go from park to drive or drive to reverse it sets down in here just like this just like that now this support if you notice it's got a wide spot right here if you look down in here you have a wide spot right here in this case but when you stick this in this tail on this rattle spring right here has to set down in here right so if you take this and put that in the wide spot you'll notice right there how that's hitting that ramp on that spring see that so now i'm gonna take it set it down in there i'm gonna push it now look where it's at you're gonna take this race lock it down in the planet now you're going to take your snap ring and put it in the case but it goes in a special manner if you look right here i'm putting it in between that anti-clump if you put that snap ring over that anti-clump like that it's going to pop out you put it in reverse you have to put that inside here just like this take that screwdriver just like that without any spring or that spring is just like that that is why it's not setting over it now we're going to go here with our thrust washer that goes against the shell they do make them in plastic and brass depending what we do if it's a race car or you know whatever it is it depends on what we put in there this is our shell you want to look at all the gears make sure there's no pity you want to put your new bushings in put that down in there the same way with the the forward planet you want to check all your gears and make sure they don't wobble and make sure the thrust washer is not knocked out of it and make sure where your bushing is going to ride is in good shape too dip in a little bit of oil spin it around now we're going to set it down on here bend it a little bit come on a little tighter take a little hammer knock it down not a metal hammer either and now you're going to take your snap ring and you can take a screwdriver and put that right in there just like that just like that now since we didn't put the shim at the bottom on that bottom bearing we're going to put a shim up here under this washer here like this fits in there perfect set it down in there just like that we have a new bushing the bushing has been put in this way where it's flush make sure you buff it a little bit just like that and you have another washer that goes right here now we're going to put our we already got our piston stuff in our forward drum you want to make sure these surfaces are good here on this shaft here that runs in this bushing you want to make sure this surface here is also good that runs on this washer 350s are bad about this area right through here you need to check it out really close you can buff your shaft with some sky sprite like we talk about clean it up nicely now we do have our forward clutches here they've already been soaked i'm just hitting one more time got our steels buffed we're still gonna leave our wave in uh it's not a hot stock converter so [Music] now this is just a stock forward clutch right here uh it's not a clutch that's coming on under load or anything like that you're gonna be idling when you put in gear and stuff like that so once it's on you ain't gonna flip it now when you put these clutch pads together this is how you identify um how do you set your plates up here see this right here the clutch ain't coming all the way to here see that right there but if you look at this plate it's got that step built into it well these plates have different steps 30 000 40 50 or whatever stuff you can pick this uh size plate to determine uh your thickness uh and your clearance on your clutch let me stick this in there if i get too thick of one then when i put it in my clutch will lock down and it won't turn perfect so now we're going to get over here to our direct drum we're going to put it together well uh when you take these drums apart you clean them with air and stuff this check ball right here will blow out real easy real easy uh i wanted to show you too on your forward drum you also have a check ball that blows out real easy when you take it apart if it blows out the clutch won't pressure up it'll go into gear but it'll slip so you want to make sure that check ball is there flip it over you can see it on both drums now what we're going to do we're going to convert this drum to a full piston style pressure drum that we're leaving this seal out right here now the pressure of the fluid is going to apply this whole piston instead of just this little bit right here now let me tell you a little secret if you leave this ring out in a lock up 350 you will not have lock up now what i mean by lockup is uh it brings the clutch on in the torque converter now to identify this is your standard 350 shaft this is your lock up shaft it has an o-ring right here if you have a 350 that has this type of shaft in it you cannot leave that seal off if you do you will not have lock up so the same way on a 204r if you leave that seal off 4l80e you leave that seal off you won't have locked up but 400 you leave it off there's no lock up anyway so you don't have to worry about that now we did put a five clutch piston in here we have these pistons shaped down 120 thousands if you get them in there and then we can add an extra clutch and get five clutches in third if you shave this piston down too far uh the steel can get uh caught under this land right here and uh won't even let the clutch come on so you got to make sure you cut that just enough i usually have 15 20 i'm done when i take them to my guy and he does them for me of course you do have to have some type of a press press that down now when you put this snap ring in these drums spin it real high rpm so they have these little lands in here to keep that snap room from coming out you don't want to put this right here you know in here to here is fine but you don't want to put that opening right there you could have you could cause a problem now since we're going back with five clutches we've already got the steels buffed up really nice are we using the high energy green clutches now if you look at this again here you notice this clutch you got that land right there see how far it's below it now anytime you go with more clutches you have to have more clearance so you have to go the thinner plate to give it even more clearance so you got to remember that more clutches more clearance if not you can burn the clutch back up and not even be using it all been set so we're just showing you what it looks like when we put it back together so now here we go again on this bushing now when you put these bushings in this big one like this you want to make sure you use a driver that's bigger that way when you put it in it goes flush like that then you come in here and you put your bushing in here that fits the bushing and you drop knock it down to where it needs to be because this bearing right here's got another step if you notice if you put it flush that steps gonna hit that bushing so you have to knock it down just a little bit to give you some slack right in here see that clearance just like that but i always use a bigger driver to put my bushings in that way i know they go in straight if you've tried to use the bushing driver that is like that it's harder to get them in dead straight so hey so that's my bushing driver i've had it for about five years six years now this is a 40 year experience bushing driver it's about a quarter inch shorter but this thing can tell you some stories yeah it sure did this is my son's about what ten years yeah probably ten years yeah ten years that's funny just worked itself around gonna turn that over flip it around there until you get him knocked roll down you heard it hit right there solid solid solid now you're gonna come over here you got your washer your snappering everything now you're gonna set this down on here just like that and i'm gonna grab this with these pliers i'm just heading i'm gonna work this slowly work it until you get that just set down in there there we go all the way down so now you're going to come in here and put your engine braking band in you got two ends they look different this one here locks into the case just like that sorry guys i'm trying to reposition my hands getting the cramp but we're going to add our intermediate clutches now we want to go steel cleaned up our new clutches soaked really nice now all right show you a little difference here uh this is a 350s intermediate steel this is a lock up 350 steel let me turn it where it looks right they're missing two teeth it doesn't matter i don't know why they did it but they did it so but they will interchange okay i i brought this shield out and i went and got another one just so you could uh see what the shininess looks like on these things this steel's in perfect shape nothing wrong with it but i'm going to hit it with my buffer and show you what it looks like these are transmission commands best friend i'm really good at this so you get kind of zoom in you can kind of see a little bit better how i turn this [Music] thing this takes about twice a round with that pad you can get these at harbor freight any places like that get this cleaned up now you can see the difference in what that looks like really nice that's about the side the waves going again so it doesn't matter but you can take and just put that in there just like that they can put your wave plate in here just like that now we're going to go ahead and assemble our pump now we've already put our bushing in and our front ceiling we glue them in and then we put our bushing in the same way we use a bigger driver to put the bushing in and then we come back with a 14 driver and uh drop it down where it needs to be that way we know that bushing is dead straight now your pump gears that make different thicknesses of these gears so we take our pump apart we'll mic them that way we get the right size uh and go that way so i'm gonna set this in here first just like set it in there i'm gonna take this gear stick it on the top of it like that and i'm gonna spin it just like that if your gear is too tall then it ain't gonna turn but you want to check this right here should only be about three thousands clearance in between here and here so just like that so you don't really have to flood these trains with training foot we fill them up here we fill them up in five minutes or two seconds i mean they fill up really quick we pump the flood in them you want to check your pump straighter everything looks good here here we've already put new bushings in it your new high pressure rings we've already put your intermediate piston in with seals you want to guide line it up with this two notches here to this wider plate right here some of these retainers right here have the springs made on them makes it look a lot easier and nicer to work with but some of these old style they just old style if you do all the modifications of this unit i'm showing you it'll work really nice for you now this is a multi-pattern so you just kind of got to turn it figure out where it needs to go got lucky that time set it on there what i like to do is grab this pump and just kind of move it like this if there's any hot spots on there i'm gonna knock them down that accidentally got put in there just moving it around a little bit do that a little bit line it back up put your your uh bolts in i'll put the bolts in so i get just a little bit of tension on this piston this retainer right here piston when i grab my speed handle we'll tighten it down to get just a little bit more tension everybody seen a speed handle before that's what one looks like i don't know if they exist but no that's all we use around here and we do have a band alignment tool that aligns the pump we put around here top down time down like this a little bit if i take your hammer if i move it around we'll take a screwdriver and look down in here and make sure you get it lined up because it will turn on you a little bit and get these holes where they're all lined up all the way around just like that they're smooth and then go and take your speed handle find it down and you're going to come and grab your torque wrench now you gotta remember this my favorite one is about 40 years old so no i'm just kidding we talked about about 12 13 inch pounds you got quiet did get quiet didn't what happened when you concentrate a lot of concentration going on i hope you all feel that in the video because there was a lot of concentration going on while i have a little time i do want to thank y'all he appreciates you all very much for watching like i say we are up here on our day off to do this for you guys having a good time here we enjoy it we enjoy it now you got your three rings one you leave off one two three this one leaves off this here is just a support it's not a ring so the bearing type pumps is the only one that's got that ring right there support if you have a washer pump it won't have that and you got to be careful too i've seen people do it i've seen them put this pressure ring in that ring right there and not even put a ring here and don't have third or reverse so you want to make sure you you don't have that problem we're gonna grab a torque converter real quick because we always like to make sure our pumps spin freely put them in so after we get it both together in just case we have a nick on our gear and it don't turn or something like that you want to check it so i think put your converter in here and turn it that tells you that my pump gear is turning free everything feels really nice so now we're going to put this thing in i've already got the gasket in some lubrication his finger is his line-up point he's just been doing it 40-something i'm gonna take a screwdriver kind of line them holes up really good and we've already put the new seals on these bolts and stuff so in the rebuild kit they get them correct so i love watching how it works let me tell you you just can't pick up a speed handle be able to do that here take some practice where did we torch those two same thing about 13 14 pounds okay you don't need me a lot now if you twerk them too much now uh it's not good you pull the threads out of this stuff so because in second gear the third it's always trying to push the pump out can't quit we're gonna set this up here real quick man he's still got it i promise we're gonna take a little break in play you can grab this right here and pick up on it let me get the camera you got a hole right here in the shaft you can stick a screwdriver in there and you pick up and see your input nice well i'm gonna take a break real quick give me something to drink got a little sweat going on my brow and uh we'll be back here in a minute we're back here precision transmissions on our 350 that we've been assembling uh got a little bit of sweat knocked off my head so we'll get this put uh back together so what we got here we're gonna be putting the parking assembly in uh normally you can tell these bolts will be at 9 16. some of them have a half inch head but most have a 9 16 but it's kind of a funny looking bolt but you take turn the output shaft where it locks it into park that way you can get in here and put this in with your finger like this and set it on there i want to get in this all right how are you getting my speed handle look at it my torque is about 20. and you want to check it that way it locks good now we've already replaced the teflon seal on this thing here it's a solid seal we put on uh this is your uh band uh engine breaking band servo it's got a little bitty washer under here you want to make sure you put that back on there that washer take it on there set your spring down in the hole kind of put your finger over this put it down in there now i've already sized this seal so it went down in there a lot easier than normal so you want to size it that's what this is i'll show you how you kind of do that you can take put that seal on and grab just like this set it down in there and you can kind of wob it around and pull it back out and it sizes it perfect kind of a little trick there but it works really easy that way now it says we're shift getting this thing out uh we're going to install two balls here instead of the four one here one here so we're just going to install these two right here like this and leave these two out now on the separate greater plates since we're shift getting this we're going to enlarge these two holes right here these are feed holes to your shift valves these right here so let's take this on here they think about a 20 000 sticker uh they're about 120 000 total in that well i'm saying actually going thicker with it how much bigger about 120 000 i'm not sure what the factory hole is okay i got you yes sir uh but this is your guide for your plate these two bolt holes here and then you've got your plate do now sometimes these bolts will be a little stiff if they'll try to grab inside metal against aluminum you want to put a little bit of oil on that bolt stick it back down in the hole just a little bit because sometimes they get drunk nothing dry they'll try to grab natalie's aluminum and it's not good same way about 10 12 pounds on these fine take your alignment bolts out and this is what it should look like just like that got your two balls in here leave your two balls out here now you've got this little s-shaped clip right here that's going to move your manual valve so you stick your manual valve in the valve body with a hole like that and come over here and stick that in right there when you can get it just like that they can slide your valve body down gently put it on the valve body gaskets put your guide bolt in the hole both of your guide bolts right here just like that and you can take them go ahead and tighten it down make sure everything moves make sure your s clip is still in your manual valve now if you get too much play here see that really not too bad you can take a screwdriver and bend this over just a little bit right here and get that in there a little bit deeper get out here [Music] oh actually i needed from my 13th i'm going to line your roller up with your rooster cone because this will be off just a little bit move a little bit side to side start at the middle and work your way out saying about 12 pounds [Music] you always want to go back over them and check them because there's so many of it's easy to miss one now this is the passive gear linkage that we're going to do away with since it's not going to run a cable to the carburetor and we just make this a little wire and push this uh around this bolt right here and anchor it the main thing when you do this you want to bend this you want to check the travel of this little valve right here it's a two stage you want to make sure you're not into the second stage any so yeah i'm not into that second stage it's got a slight spring there and then it gets a heavier strength for the rest of it you just do not want to go into that when you do this and there you go got a nice little brass filter i like these better over the plastic but both of them are cleanable don't forget your gasket there we go valve body on shifter all set up everything looks really good looking good now we only use cork gaskets no matter on all units that we do they just work really good uh we don't put any sealer on them or anything like that they need to go on totally dry on a chrome pan make sure you buff as much chrome off of it as you can get the gasket kind of stick to it [Music] sorry it takes a long time i bet you're still on record time on putting one of these together well [Music] now anytime we put a pan on it guys we always use the speed handle you know how you look at it we'll go around and sink it with the speed handle and it'll never leak we just don't have no issues we just come around just kind of hit it feel it feel it you can feel it stop don't stop until it stops same way the main thing was getting equal all the way around if you can feel the spin stop stop stop stop now the next time it goes around it's going to get a little tighter you can feel it slowly cinching down but it'll keep moving it keeps on moving forward it's kind of weird how they settle in see it's starting to snow down good now now tomorrow we come back in you might be able to even hit it a little bit more because it might shrink just a little bit more but that's how you do a pan gasket two or anything like that or impact so we got our one two accumulator right here this is what softens the one two shift since we left our two check balls out in the valve body it's going to firm up second gear anyway uh we left our uh wave in the second gear clutch to soften it anyway too so we're going to go ahead and put the accumulator in and then we're going to kind of stretch this o-ring a little bit and we're going to set it down in here if you notice it sits right pretty in that groove now if we put this training together and we still think it doesn't shift hard enough in second gear which it probably going to work really nice you can leave this spring out and it's going to firm it up a bunch but i like to mess with leave the spring option at my choice because if i don't like where second gear shifts i don't have to pull the pan off or put check balls back in change my holes or anything like that in the plate i can always go back to this spring and take it in or out so i'm going to put this back in if i don't like it i don't think it works shifts good enough for the power of the motor i'll take this spring back out so we'll put it in for now put a little oil on this piston you put it in at an angle just like that because it's so easy to cut that o-ring so i'm going to take that like that i'm gonna take this rubber mallet trying to smash my finger and i'm gonna tap it in there just like that and hold it with my thumb it's kind of hard to do stick that down in there push that in it just like that that thing is seated really good down so you're good to go right there so we've got the next step is going to be our vacuum modulator there's really no tricks to it just make sure the hole is clean it blows out good stuff like that put it in now the vacuum modulator we always go with an adjustable style that has a screw in the end of it right here if we wanted to shift a little later or just a little bit firmer we could screw this screw in now we can take and screw that screw and it'll take all the shifts to make take them up or down it will not separate them you can't take the third move it up or the second move it down it's going to move them both up or down to do the other thing you got to take it apart and work the valve body over to do anything like that they have here about 12 pounds would be fine as well now we already blocked his uh passenger cable off and did the modifications on the inside for it we're gonna go ahead and uh put our governor in we're gonna put a little hole on it put it in where it touches all the way just like that now these overhaul kits always come with a little black o-ring that you can put on right here i never use it because when i put it on it squirts out the top or something like that so i always take a good rtv that just put me a bead all the way around this cover just like that just take a smoothie with your finger just a little bit just like that then when you put this cover on here like this i want you to take turn it move it around just a little bit kind of move that stuff around a little bit just like that and then you're going to take and put it on it's going to pour it out no matter how you look at it what we do is come grab a little chisel or something or some type of and put that all the way on just like that now if you need to set your governor depth to back and forth moving on it like this what we do is we you can take and tap in on this cover just a little bit like this with a little hammer tap on that and come in and check it you don't want it solid you want just a little bit of movement just like that and you're fine grab your clip that holds the cover on and put it on real simple now to do the speedometer gear you always want to put a little bit oil on this shaft a little bit on the gear you want to put this tab right here in the hole just like that you want to slide this gear over it just like that the gear is going to be tight so it's not going to go on we have a little tool that we've had for 40 years we'll take it just sit there and tap that thing off just nice and pretty it's behind the little flap right here that holds the gear on it's on where it needs to be that way you don't break it these are real easy to break our tail housing we've already got our seal in and our bushing we're going to put our seal on it go square all the way around uh about 30 pounds is fine on those now we get back to the speedometer gear these things are notoriously leaking but the the depth in here you can actually get two seals in here if you do it so what we're gonna do i had an extra seal one come in the kit so we're gonna stick it down in here and we're gonna slide it down in there just like that it's nice and flush then you're going to grab the other one make sure it's pointing the right direction stick it in there just like that now you've got two seals well you got this little wire retainer that holds them seals in you can take it stick that right back in there too just like that so now when you stick the gear in you got two nice seals right here on the end and you don't have to worry about leaking because it never leaks here always here put your little oil on it slide it in there you go now this does go a certain way it's got a tab that sits on there just like that so you want to point it right when you stick it in here we got our 350 back together all performance clutches and stuff all new bushings uh going behind a 68 camaro with a big block 396 should make five or six hundred uh and this one training should hold up pretty nice we'll get it all painted up and stuff for the gentleman and get it in his car for him if you all need anything done give us a hard precision transmission we do it right come by and see us have a good day
