I noticed this:

 

 

while under the car today.

 

I've been browsing RockAuto for the proper seal, but can't seem to figure it out. Output shaft seal? Extension seal?

That could be anything. The joint in the gearbox you can see has no seal, just maybe a smear of gasket "goo".

I wouldn't be too concerned about it, that just looks like 20+ years of build up. If it was really leaking bad enough to worry about, there'd be a lot more dust clinging to the oil on a lot more parts.

I wouldn't concern yourself with it, that's actually amazingly clean. This is the old tired trans I pulled out of my GL.

 

 

 

The blue paint can cap is just a plug to keep it from pissing all the oil out when I pulled it.

Well alright, I'll just ignore that then.

 

Thanks fellas!

 

Damn, look at that thing! How many miles were on it?

I dunno, a bazillion? I doubt anybody really knows for sure. It did make terrible bearing noises and ground into every gear, though!
