I've got a bit of a leak myself, on a TH400. Thought it was the pan, but nope. I'm pretty sure it's my shift linkage seal, but haven't tried putting that in yet. Watching to hear what the transmission masters say!

a bad bushing in the pump would. I had my TH400 out and cleaned the heck out of it and resealed. I just pulled my pump and took it in to a local shop. They disassembled and inspected the pump, pressed out the bushing and seal, cleaned it in the parts washer, then put a new bushing and seal in before putting the pump back together.... all in for $20 and about 20 minutes of time. I've been running it for a few weeks now and no leaks so far.

Now I understand, I was thinking torque converter when you typed tc, not transfer case. The little rubber grommet for dipstick tube is easy enough to replace.
