Transmission not happy.

Today I did the clutch in my 92 5 speed XJ. Drove it all day no problem, later that night it started getting hard to shift, so I crawled under to take a gander and then entire transmission crossmember is covered in gear oil. All of the transmission mount and everything.

Anyone know where it could be leaking from?

from the slave?

If you're sure you put the fill plug back in, and it's gear oil and not hydraulic fluid, might be leaking from what's called the rear adapter seal http://www.just4jeep.com/catalog/product6067.html in between the tranny and transfer case. Happens sometimes if the tranny is overfull, but if you have a lot of gear oil dripping off the trans mount, then it's probably a blown seal.

When you replaced the internal slave cylinder/throwout bearing, did you leave the transfer case and trans as one unit, or take them apart?

We never took them apart, we never even drained the tranny...

Yes it is gear oil and not brake fluid that is leaking.

Clean the area off and look for a crack or a leak from gasket or speedo gear, etc...

Or did you damage the rear seal by accident?

I just remembered that I had never put the vent tube back ont othe transmission. Could this possibly be where it's leaking out of?
