you may use the wrong

fluid

, you may change it incorrectly, and you may not even want to change it now. The first thing I want to do is dispel the myth that modern automatic

transmission

fluids never need to be changed be

cause

they are lifetime fluids, load a bunk if you ask a modern engineer they will tell you oh you have lifetime fluid, the fluid It's good for the entire life of the transmission, but let's say your transmission the warranty is 60,000 miles if it breaks after that they don't care they will sell you another car or another transmission take my old celica it has like 240,000 miles per hour I change the fluid every 60,000 miles it still runs fine if it would have broken at 60,000 miles it would have strangled someone but let's say you're a bad boy or girl you never changed the fluid you have 180,000 miles on it now if you change the fluid and the filter at that mileage and it has never been like that.

Touched too many times, the transmission will start to slip or not work at all, so do it regularly if it is too far along, pray it lasts as long as possible. Now this particular vehicle is a 2015 Toyota Sienna. I advise you to change it. every 60 thousand miles or so and as you can see it has 77,000 miles and has never changed it but it's a toyota it's fine, it's not going to hurt anything so we'll start with the obvious, let's look carefully for the dipstick it has a dipstick oil, but t

here

is no transmission dipstick on this toyota.

They followed all the other fools who got rid of the dipstick. Mazda did it years ago. It's a stupid design, but that's what it is, so you have to deal with what you have. They are fantastic vehicles, a bit flawed design, this is how you make the fluid yourself, first you lift the vehicle in the air, you want a jacket so the wheel stays in the air, they get a big old jack stand, this is Changing fluids is generally a dirty job. putting on these work gloves they are fantastic they go all the way up to your neck so you don't really get dirty at all now to see what you're doing it's a lot easier to remove the tire well I guess the second time over and over again and around it goes t

here

now once you get underneath here's the drain plug right there the drain pan underneath this is the six millimeter hex head so we're going to put it on the end of a ratchet they're pretty tight , so you have to pull it pretty hard but eventually it comes loose now we can do it with our fingers and drain it in the pan and there it goes if you notice that there is only a little bit here because there is a trick and voila, you get a length of six millimeters.

Hex, put your hand inside and there's a piece here that we have to take out. Now you can see why I'm wearing gloves. We continue screwing it. You can see it's starting to come out and once we get it out you'll see what happens. that's where most of the liquid comes out, I'm going to take this piece out, you won't get much liquid out, but realize that even when you take this out, only a small percentage of the liquid comes out, so it's a good idea to change it. do it every 40 50 000 miles because you want to remove most of the dirt and if you keep

changing

it to keep it clean it still has a lot of old fluid in it but it's a pretty good fluid now.

I never recommend washing them. things could have all kinds of problems, so it's a good idea every 40 or 50,000 miles or so to change the fluid you're changing, maybe a third of the fluid that's in there, but it's a very good, highly refined fluid that, If you do that, we're going to get most of the dirt out and of course the bolts at the bottom, all the mud that's in here is going to come out now, it's never going to stop dripping completely, so when it's almost done like this, screw this in flush. and you realize it's a piece of plastic, you don't want to break it, so once you feel it bottom out like that, just give it a little bit that's good enough, you can reuse the gasket as long as it's clean, they last a long time. you want to do it with your fingers and finish it with the ratchet so it doesn't drip, but since there's no dipstick, how do you put it back in?

You have to remove this crap, that's why we removed the wheel. I have to take this plastic thing off. This one comes off a little rusty. I've been sitting there for a while. Oh yes, things are tight there. I still can't even turn it under my fingers. Are you there. I'm getting weaker. Now they are those stupid ones. plastic stuff, you push it in, you hear it click and then I wait for it to come out, at least in theory I did, and there's the filler cap, which turns out to be 24 millimeters now, can often be a bad smell take them out, so I have a long little extension. bar here I have it loose now the next question is what type of fluid do you use, you can always go get one from the dealer, you know they will have the right one for it, but in this case, if you look for it, it says you need toyota ws well, I have been using valvoline for a while when you look at the back and as you can see here it says toyota lexus blah blah blah blah ws so this works for the ws now since it doesn't have a dipstick how do you do it?

I know how much to put back in, well this is easy because it's my son's car, it's never been touched, it has the right amount of fluid to begin with, but first you have to look at the transmission, you can see this baby is completely dry, no it has leaks. If it has leaked, then it will be a real job trying to figure out how much to put in, so if you think your transmission is low on fluid, you'll want to pay a mechanic to do this job. I have special tools to measure the temperature of the transmission.

The transmission goes through a whole host of pointless things to make sure it's filled correctly, but if the transmission is dry, especially if you're the original owner, all you have to do is this, This is what came out of the broadcast, I'm not sure it's a bother and I. I also long for the old days when you can have a dipstick to measure it, but that's what everyone has been through, so you get a bottle, make it in a bucket, so if you spill a little it won't make a mess and see how much comes out.

Let's check it to see if it's starting to fill, it's 700 milliliters, so we'll pour this in there and measure the rest because I know it won't spill because there's less than a quarter left and we measure the rest, 650 milliliters, so that's it. 350 milliliters now the bottle is 946, so we'll put a whole bottle in and use this great handy pump, we just put one end here, it fits nice and hot that goes in there and the other end of the pump goes in here. and we'll pump it all out, yeah, as you can see, it starts to flow and when this one is empty, we'll just pour 404 milliliters back in here to fill it up, that's how these clear bottles come in handy, you can pour the right amount.

My advice is don't fill one and guess empty part of the full one, take it out until it's set to the right amount you need so when you pump it you just pump until it's empty and don't guess and accidentally put it in. too much, yes, we will pump again here. These are useful little pumps, they don't cost much and work very well. I got this one at Autozone which works perfectly fine. Now you notice that some of the liquid is dripping. That's another way of I'll show you it's full when it starts to leak. It's full, so we measure it correctly and paste it here first.

We will tighten it with our fingers. You already have the meeting. You can use it on top. It is an aluminum joint. They basically last forever and then they wear off. your big old bar, stick it on, but once you finally get it on, the nice tight soap won't come off, don't worry about taking it off next time because with this giant bar it will always break, put this plastic thing back on and stick it on What you do is you push them back out now they are ready to go in so you can line them up, you go into a hole when you twist them and then when you push them in it snaps into place, same as with the bottom. one sometimes you have to turn it a little to get them in a hole because they are old and brittle, there we go and then you push it to lock it and put it in, of course this has to be tightened with a wrench once you tighten it with your fingers and then it doesn't Don't forget to put the wheel back on, one is always missing, it always happens like this and now we're going to tighten them with this, but you don't want to use the impact wrench to put it together, just use it to grab it. aside you need a torque wrench to do it right now you're pulling out a jack and we get our torque wrench in this case it weighs about 75 pounds so we're going to go to 470 one two three four five and we're going to leave it down and now we're going to finish the job properly so that the wheels are in the right position, just keep turning it until it clicks, there's one, you go opposite sides, two, three, four, always double check your work there and that's it, now realize this 2015 sienna has a six . speed automatic transmission a conventional automatic transmission many cars today have cvt transmissions and those constantly variable transmissions it is even more important to have the fluid changed regularly if i had one but i don't but if i did i would change the fluid every 30,000 miles, you can see, is not a difficult job to do.

I would rather spend time doing it every 30,000 miles than have the transmission die. Take a Nissan Jackal automatic transmission, those are horrible if you don't shift them. They will fall apart faster and probably break anyway, but at least you will have a longer life if you change the fluid in them, so now you know the truth about changing automatic transmission fluid so you can take care of your car and make it last. the more possible. as long as possible and believe me, do it yourself. I've known people who paid shops to do it and they did it wrong or didn't even change the fluid, do it yourself, do it right, so if you don't want to miss another one of my new car repair videos remember to ring that bell
