flinchy,

I'm not familiar with the GC 231 TC vent, but you might want to check to see if the TC vent is plugged. Follow the vent tube off the TC to the vent (probably in the engine bay near the transmission dip stick tube).

I know XJ's, starting in '97, had a strange vent that would easily plug up.

Over serviced TC's and TC's with plugged vents may cause leaking past seals.

Here's a pic of the XJ vent hose and vent that I mentioned, and a close-up of the vent itself.

You might also want to check the "O" ring on the speed sensor.

Are you sure its the Xfer-case leaking? A rear seal on the trans could bathe the Xfer-case in Dex-III
