Help Identifying Trans Seal

Post by benpineapple » Mon Nov 14, 2016 8:09 am

Good morning!

Pulled my motor this past weekend to address a trans that went from leaking ~1/4qt per week, to leaking ~1qt per week. I replaced DS output shaft seal, trans pump seal (behind torque converter), and the RMS. Hit a snag though, it appears the leak all along was coming from one of the seals between the angle gear and the transmission, and there are 2 seals I cannot identify after hours scouring diagrams and part numbers.

The protruding steel collar is what slides into the angle gear, connecting the trans to the angle gear. I'm pretty sure seal 1 is the culprit behind the leak.

Let me know if you have more questions.

There are a total of three (3) seals in the angle gear area.
Stick to Corteco.

It is a hard one to find on the drawings on Vida. I don't have access to my computer with Vida on it until later on. If you don't get an answer by then I'll find it for you. I had the angle gear re-built with new shaft and seals so I should have the parts listing somewhere. Difference is mine has a 5 speed auto, but I'll confirm what the 4 speed is.

Hey thanks for chiming in cn90 and scot850. Went to the dealership last night, pretty sure we got it figured out. Looks like seal #1 (outer seal) is part number: 9496129 for the aw50-42 transmission. I was sold the wrong seals to begin with, because my VIN # showed a different transmission on the car. The transmission was replaced by a PO at some point.

I'll be reinstalling everything on Thursday. Also going to take apart the angle gear to get access to the angle gear collar seal (collar on angle-gear side that inserts into the angle gear sleeve).

Side question: I've seen a few mentions that when reinstalling the angle gear, people have thoroughly cleaned the angle gear sleeve, and put loctite on the inside? This a good or bad idea? I have anaerobic sealant I'll be using on the outside, but loctite on the inside sounded odd to me.

I have not heard Loctite but have seen people using grease inside the sleeve to prevent future rust.

This design (sleeve) is not very good engineering, there is no warranty the new sleeve won't be stripped again, especially under load such as wheels slipping in the snow then cacthes on dry pavement again.
For that reason, I left the sleeve alone in my 2005 XC90 2.5T AWD, which is a FWD now.

Like cn90 not heard of the Loctite suggestion.

Glad you got the part issue sorted out. Sorry got busy last night and didn't get a chance to look into it. Wouldn't help that it is not the original trans as I would have got it wrong also. Dealer has done a good job if they managed to sort it out for you. Good luck!
