Transmission oil leak in the tunnel

[kavadarci]

Hi,while I’m waiting for my Stomski coupler I removed the old in the tunnel and found some green oil (I use swepco for my transmission).

Does anyone know where is this coming from and how can I stop it?
Thank you.

Leaky shift rod seal. Some guys have been successful R&Ring it with the trans in place.

One option is to check periodically. A little leak you could put up with for a long long time.

The schemes people have given for doing this in situ generally involve drilling a couple of small holes in the steel outer part of the seal (not much room for an ordinary drill) and screwing in some self tapping screws, which you can grab and use to pry the old seal out. I've not done it, but seems feasible.

Do a search for the procedure. This leak is very common - think how old the seal probably is.

Thank you
I’m installing rennline cover so I should be able to see how much oil I get in there.

As others have stated, shift shaft seal. Not that hard to do if car in in the air on a lift. Have done a few.

Cheers

What am I missing here I don't see any oil in the photo?

I wondered about that, too. Looks like a bit of red oil on the shaft. The rubber boot looks awfully shiny for an old boot. But since he said he found green, I assumed it was on the shaft, or that he had pulled the boot and found oil in the boot (which is the first place you would find it if the boot was good).

Maybe he pulled the boot, and cleaned it, which is why it looks so nice?

Which is why, if it hasn't gotten beyond the boot, and the oil level in the transmission is at the right height, it might not be an immediate worry.

+1, replace the seal it's simple.

[kavadarci]

Yes,
It was inside the seal and pooped a little bit. Photo is after I cleaned it.
If it’s not that hard to remove it with the engine in the car I’ll do it.

Someone did a great write up about taking it out with a small screwdriver between the shaft and the seal. Going to have to do mine too. Had oil under the rubber flooring.

I'm doing this.
is this the right seal:

The trick is to not tap it in too far. The shaft starts to taper on the inside of the gearbox. If you drive it in too far, it will leak. To be honest I've always had a heck of a time avoiding leads with that seal.
