Got a new to me 1991 Jeep Cherokee 4.0L 4WD. Tranny leak problems
I got a 1991 Jeep Cherokee while my 91 camaro undergoes a LSx swap. So, it seems to have a transmission leak as I put UV detector in the tranny and it's on the floor. Anyway, where are the most common places I need to replace seals? I already got the transmission out, I just need to replace some seals. I already replaced the front shaft seal and need to do both pinion seals. Any recommendations as to what other seals I need to replace? Is there a seal between the bellhousing and transmission?

the rear seal where then driveshaft goes into the tranny, unless it is 4x4 then separate the tranny and the transfer-case and replace both input and output seals on both tranny and t-case

There is a sleeve in the front pump where the torque converter goes thru, it can wear out. I had a 94 do that and it leaked like a sieve, if that is the case you will have to replace the front pump.

It can still be a slow leak, my AW4 leaked slow at first. When I finally found where it was leaking, I took the pump out. Figuring it was just a sleeve I took it to a couple transmission shops to see if it could be changed, they said no. I bought a new pump and converter from DACCO, they were the least expensive. Or at least the least expensive I could find, and they supply the local parts stores.
