Changing Transmission Fluid and Filter on Cavalier 3T40/ TH125

How to change the transmission fluid and filter on a General Motors 3T40/ TH125 transmission. The trans is in a 2001 Chevy Cavalier 2.2

Thanks for the video man, surprised how much of a difference it made in the car emidietly

Interesting how your magnet was in a different place than mine was. Maybe it doesn't matter too much, as long as its not squeezed between the pan and the filter. GM probably made about ten million of these transmissions, across a couple decades of vehicles, so there is likely some differences. One clever trick is to carefully pour your old fluid into a bucket or a pail, and then fill an identical bucket or pail with new fluid so that way you'll be adding exactly the same amount that you drained out. This assumes of course that not too much spilled on the ground.

[@AlexandroBenelli]

Great but the manual says 3.7 L of fluid total if you are g to replace the filter

Mi cavalier es 4cil motor 2.2 pero no tare la valloneta allí para el aceite de la transmisión y no se la encuentro

[@ricks.8522]

have you ever thought about getting into one of the trans cooler lines and flushing all of it out? I have done it many times .... works great. Another trick I have found is to use some Auto-RX in it ... I have a 96 Dodge van that had a somewhat hard shift from 2nd to 3rd ... now it seems to be working much better after only about 150 miles .... I will drive it for abut 2,500 miles and then do a total fluid change ( pushing all the fluid out of one of the cooler lines ) .... there is a guy named Don Smith who has a lot of videos on this process ... it is pretty simple, really .... here is one of his latest videos showing how he does it ........ kzbin.info/www/bejne/b3axp4iPipaSerc

Considering the old fluid still looked pretty good I think just dropping the pan was good enough. Whatever old fluid got left behind is still probably okay. Also I put a new radiator in this car a couple years ago so it's got a new trans cooler. My girlfriend daily drives this car and she says it's shifting smoother since I changed the fluid and filter. It shifted good before but the 1st to 2nd upshift was a little bit hard.

Dude , that was a good video. He really cleans out all of the fluid, im wondering if it works the same on these old cavaliers.

Great video. I'm thinking about buying one of these & am doing research. I know this one doesn't have a drain hole so it's messy but if you can get a big enough thing to catch the fluid you can get a rough measure of how much to refill. I use a bucket with my truck, add a jug of new fluid, refill the jug and see how much used is left in the bucket. Vice Grip Garage also has me in the habit of writing the date & mileage on the pan so whoever is under there next will know when it was changed.

Looks like a messy job lol

[@thomasbardwell4151]

I changed mine because it won’t shift,didn’t fix it...

[@justinw523]

Did you ever figure out what the problem to yours was?

thomas bardwell I just bought a 89 Beretta GTU that I thought the TCC was bad and it’s doing the same thing not wanting to shift from 1st I have felt it shift all the gears but it they was late shifts at about 3,500 to 4k rpm’s. I’m hoping that the fluid and filter fixes it cause it has 98k original miles and I don’t think it’s been changed since the car was bought new
