How to Service a Sealed Toyota Transmission

hey YouTube it's Faye and for today's video I'm gonna share with you how to service the fluid on your Toyota if you have one of those dreaded seals automatic transmissions so the subject car for the first part of this video at the drain and fill is a 2006 lexus 470 and this is the a 750 F transmission and I'm going to show you the check procedure on this 2009 Tacoma and this one has the a 750 II transmission so here goes tools you need for this job pocket screwdriver a 24 millimeter socket a shallow one preferably a 14 millimeter socket doesn't matter what size a beaker a somewhat low-profile beaker the ws fluid how many of these is gonna depend on how many flushes you want to do I normally like to get the ws from Toyota however the customer supplied this and it does they that it meets the standards for WS so that's fine however you know I recommended the Toyota and I recommend Twitter to you oh and one of these I got those from Jegs I'll link it below I could also just get a hand pump this is just so much easier for me and I don't like making a mess so this is good the first thing I do is I put an entire court in there and then I empty it back in now this only ever holds clean fluid and only clean WS I do a lot of these services so it makes sense I buy this but same for you if you're gonna be using this make sure that these should only use clean WS in it or clean it out every single time then of course what I do is I pump it back into the bottle so that whatever is left I know like that's that's my baseline I'm never gonna be able to get that back into the transmission so I'm gonna drain it out measure it dump this measure out my clean fluid put my clean fluid into here and then put that back into the transmission so here goes and on this transmission the drain plug is right here it's a 14 millimeter plug and then up above all the way up here I know it's hard to see against neke my hand yeah all the way up here is the fill plug and you always want to undo this one first and just make sure that you can actually open it anew it's really hard to see but if I you can see that it says WS on it and that's how you know that it's for the transmission and not for obviously the transfer case because that doesn't take ws fluid and also the fill plug for the transfer case you've got the drain here and the fill here for the transfer case so it only makes sense but this one up here that says WS is going to be for the transmission the other plug we have down here is the check plug this transmission has zero fluid leaks so I know that all I'm gonna do is drain out fluid and then measure it and then fill it back up with the same amount of fluid and the fill plug simple as that in order to get to the fill plug I'm gonna start by removing this little clip out of the way there we go just so that I'll have a little more access easily to my fill plug there okay first things first to make sure that I can remove this in this I can notice the fill plug has a rubber o-ring what's another way you can differentiate it and there's a better look at the WS marking on it so you really can't mess this up no matter what transmission now I've got my bucket underneath my drain plug just gonna go ahead and remove that 14 millimeter bolts let that fluid drain out [Music] you can tell the condition of the fluid is pretty poor however this service has been done before on this vehicle with regular service intervals meaning around every sixty thousand miles we can see it filling up and yeah about two and a half three quarts typically what you'll find in these for just a drain and fill when the transmission is cold and I actually have enough fluid to maybe do three or four driving fills definitely a minimum of two but the more the better and I'm not gonna replace this for adjust the flushes but at the very end when I do my last flush I'm gonna replace that gasket gonna link the part number down below okay we can see it stopped just barely underneath 2500 milliliters at that old fluid in the light look then I just poured it into a container that's not going to leak and then I can just bring it to an O'Reilly is there autozone or build chains place and recycle it like engine oil and using the clean rags I just wipe out the entire inside of this container and make sure that it is super frickin clean because I'm gonna fill this one up using what the customer provided which does does meet the Toyota WS specification but once again I do recommend getting the actual fluid from Toyota I filled this to the exact same amount a little under 25 and then of course I've already have this build for what will be left behind I poured in my pre measured out amount and this fits underneath here perfectly [Music] and then I'm gonna pump until all that fluid is in the pan and after it's all in there it's just super easy you just close that and it pinches off make sure that none gets all over this person's Drive like a little bit bounce and then just actually clicks right on the side look how often that is I'm also going to reattach this shift selector right now because I'm going to cycle the vehicle through all the gears before I drain the fluid again so that guy's not going anywhere and let's start up the truck most important are going from park to reverse to neutral to drive you don't really need to do these two I just kind of do them anyways because why not try to do like a three count for each one and I will do this about three to five times front to back okay and here's my second dream you know it looks a lot more pink it still is pretty nasty that's because the system can hold anywhere from 12 to 15 quarts of fluid so the reason why I like to cycle it through to make sure that as much of that new fluid gets into the torque converter and cycles out the old stuff as much as possible so I'm gonna do this a bunch of times and hopefully the fluid up and comes out really clean one last thing to note is depending on how long you spent cycling through the gears you just want to make sure that the transmission fluid is cold when you do this because obviously you're going to be measuring fluid like for like so if you're gonna be putting in cold fluid you need to make sure that you're emptying out cold fluid because the volume is going to change you definitely want to be sure that you're as accurate as possible well the first time they drains it out all the fluid had sort of settled in the pan this time I had run the engine and the transmission started pumping fluid all the way around so never assume the fluid level always measure it and always put in exactly what you take out so this is drain number two and then from there I'll repeat the drain and fill procedure until I'm satisfied with the color that the fluid comes out at the final flush or until of Jena a reasonable amount of times or I ran out of fluid so in this case I did that service four times for drain and fills this is my final reinstallation of this drain plug so I'm gonna replace this you can tell that it's it's flat it's sandwich but the one that I brought with me today is this copper crush washer I brought a few different sizes here's another size this one actually isn't going to work just make sure to see how there is a little shoulder right there this one isn't gonna work because you don't want it to sit on the shoulder there it's not gonna seat properly this one here is copper crush washer is a great choice because it fits nicely over past the shoulder and it's new and it'll crush really well and if you want to get all sorts of fancy here is the actual and yes I did get two because the same one is used for the check plug and the drain plug and they both get torqued to 15 foot-pounds like I said you don't have to replace the crush washer in between every single drain and fill but definitely replace that at the end of the service that you don't have any leaks so the next step would be to check the fluid level now for some of you if your transmission has zero leaks like the Lexus and you know that the fluid was at a safe level prior to you servicing it just following the steps in the first part of this video may be enough for you however if you have a leak in your system or if it has been serviced before and you haven't had a chance to test drive the car so you cannot verify that the fluid level is good then you'll want to perform a check tools that you will need for this job first of all a clean drain pan to catch whatever falls out of that check plug if you happen to you overfill or if you overfill on purpose at the end of your service just that you can perform an accurate check a lot of people like to do that and I think that's a great idea a shop chicken is always helpful for catching any bugs that are underneath the vehicle that you're working on so they don't end up in your hair and then a five millimeter allen key socket I do like using the sockets that I'll be able to put it on the end of a ratchet because people love to over tighten the heck out of everything and you never really know lastly we're gonna need to have our tech stream plugged into the OBD port of our vehicle here and yes I also have this thermal gun just because I see a lot of people using this instead of tech stream or an equivalent software that can communicate with the transmission so I'm just gonna give sort of a side-by-side comparison for what tech stream reads versus what this reads now if you have one of these thermal guns and you know the level of accuracy already or you have something else that you can corroborate it with and you feel comfortable with that that's fine just notice that there is a difference between reading the actual sensor from text stream and then reading the outside of the metal transmission pan with a thermal gun so here goes so we will begin by turning the vehicle on but not starting the engine just yet and then on tech stream we will connect to the vehicle and that will take a second right now you can see that it's recognized okay Toyota Tacoma 2009 there's our engines also going to ask you for any options there's going to be a whole series of options here for this one particular circumstance though for checking transmission fluid it doesn't matter you can pick whatever if you have a question about traction control or if you have a question about smart key and you don't know don't worry pick whatever you want in this instance great and from here we're gonna go to the engine and ect section and we're gonna choose data list and then here you can see we have so many different options for all the readings that are available I'm gonna scroll over until I find what I'm looking for and here we have a couple readings at the very end you can see here automatic transmission oil temperature one and two and you can see that they're both the same and they both are measured in Fahrenheit so this is what I'm gonna be using when I take my reading ok so right now as you can see before we have a transmission temperature reading of seventy nine point two degrees Fahrenheit now let's say you wanted to read Celsius you could absolutely change the text room over to Celsius that's a different tutorial for a different day right now we're just gonna take readings in Fahrenheit so obviously seventy nine point two is not in the range where you want to take the reading the reading should be taken between ninety seven degrees Fahrenheit and 115 degrees Fahrenheit so in order to achieve that I'm gonna have to heat up the transmission by running the vehicle for a little bit I'm gonna start the truck and let it idle until I see the range that I want to see and then I'll also verify that will corroborate with our thermal gun to sort of compare and contrast now one thing also to make note of is that before you do this make sure that your vehicle is parked on a level surface it's easy for me with the truck because literally I can just stick a level in the bed this surface is a little bit uneven so I had to do a little bit of trial and error to get it in a safe spot but I'm at a safe spot now we're a little bubble in my level is right between the lines you don't have to get that scientific I'm just a perfectionist about everything so we're gonna go ahead and start the truck as the transmission temperature rises and come back in a second would you look at bat now we are within specification so let's go underneath the vehicle and see a couple things first of all let's see what we've read down here with this guy and that's not too far off you can see how close I am to the transmission so looks like it's just a few degrees low just to give you a fuller picture of what you should expect the speed I went ahead and added about a half a quart more of fluids this you'll be able to see it flowing out from being too full and then the drips that it should look like when it is at the perfect level so here goes we're trying to do it where I can actually be doing it and show you at the same time so hitter check for okay and here you can see this is what to full looks like so I'm just going to keep an eye on it until it gets to a trickle bzz okay and that's about good so there are some people that believe that once you drain all of it out and there's no more trickle at all close it up and then add a little bit more fluid some people say a quarter to a third of a quart I don't really subscribe to that method of what I do is I wait until it trickles so it makes that noise in your drain pan and then I put the plug back in torque it to specification and then I'm done so I hope that you enjoyed this video and found it useful I hope that it helps you in performing a service on your own sealed automatic Toyota transmission and I hope you don't forget to buy the actual toy to WS fluid no I am NOT a Toyota snob rather than some imposter so I'll see you in my next video [Music] [Music] another interesting thing to note is that on this transmission for the two-wheel drive you can see that the fill plug is right here on the tail shaft so a two real drivers a spore wheel drive of this transmission is a little different [Music] [Music]
