Default tranny leak (updated with pics)...

Well it seems like my transmission developed a leak.

I see this on the ground today and lift her up to take a look:


raise her up and looks like the whole rail bolted to the tranny is covered in oil.


I look further and there is oil very slowly (like a few drops a day) coming out somewhere around the shift turret or where the driveshaft connects to tranny.




Now at this time I cant figure out where exactly its coming from, but it really looks like its near the shifter. I had the rubber thingy on the shifter replaced a few weeks ago, as well as that really small rubber that plugs up the transmission around the shifter with brand new ones, so I know it cant be from there.
Are the seals around the driveshaft prone to starting to leak? can it be somewhere around the shifter other than the rubber piece held on by the 3 bolts covering the shifter hole?
any suggestions?

I will investigate this furter tomorrow.
any input or suggestions is welcome.
-Vlad

18psi, I also have a tranny leak somewhere, but it is collecting on the drain bolt. Could be leaking through the rear seal?

well Its either that or somewhere around the turret. I'm really just hoping someone had something similar and diagnosed it so I can get some input before I have at it tomorrow.

how bad is yours leaking? I would say mine is about 10 little drops a day ( a whole day standing)

mine definitely isn't leaking 10 drops a day, at most maybe 1 drop every few days to a week. It is obvious the bottom of the transmission is covered in the stuff, it just isn't to the point of dripping constantly, simply coating the tranny.

It's probably the rear seal, since the only thing that'd come from the turret would be leaking from the drain hole. But the turret sits further back than the end of the tail shaft.

Looks like the rear seal to me. I doubt that much oil would come from the turret.

Rear seal is PN: M507-17-335A

The title of this thread sounds gross.

so how hard will it be to replace the seal? do I have to pull the tranny? or is it simply taking the driveshaft off and replacing the seal?

Edit due to not paying attention to what seal was being referenced.

Isolate the problem. IE-clean that transmission spotless and drive it a bit and figure out where the leak is actually coming from. No sense in pulling the transmission if it's the turret leaking. Check. They could have overfilled it or something.

It is not engine oil. it is transmission oil thats leaking. So my guess is that its the seal where the driveshaft goes into the tranny. and yes, I will hit up the whole thing with cleaner tomorrow and wipe it down, so I can see exactly where its coming from. The transmission oil is not overfilled, I changed that a couple months ago and did everything by the book.

The rear seal is easy to replace. Just remove the driveshaft. Pry the old seal out and slowly work the new seal in. The new one will press right into the rear of the transmission. I think Pat has a good idea though. Clean it up really good, and watch it for a few days. It could just look like that rear seal.

Ok, so today I bought 4 cans of that engine degreaser/cleaner stuff and just went nuts on the engine/tranny/underside of the car:

came out pretty clean and though no pics of the underneath, it is pretty darn clean under there. now I just wait and see if the leak reappears and where.

to say more... where are 18psi of boost you fake!


anyways... its probably rear seal... if you replace it, dont forget to replace that bushing that goes with it or your seal will start leaking within a week or so.
