leaking atf

i having some issue with diagnosing my 97 wrangler 2.5 auto leaking ATF. i have replaced both seals in the housing where it was originally leaking from. however it is still leaking. if the jeep runs in the driveway nothing. it only seems to leak when i drive the jeep. any ideas on how to seal this. the bearing for the shaft was also replaced while i was in there. not sure why it would only leak when being driven.

I had a difficult to diagnose ATF leak once that turned out to be caused by a cut o-ring on the speedometer gear housing that seals it to the transfer case.

Sounds like the transmission's output shaft seal is simply still leaking... perhaps from not having been properly installed or the wrong seal was used.

you think a new seal and some RTV will stop it?

update on this issue. the seal at the back of the transmision was leaking due to a short input shaft on the transfer case. issue has been solved by useing the teraflex extension seal.

So your automatic was added later or your t-case was replaced by one set up for a manual transmission? Those are the only reasons that would have happened... which would have been good to know since I would have suggested the extended output shaft seal from Tera right away. I had to install one into my previous TJ after I converted it from its OE 5-speed to an automatic for the same reason yours was leaking... the input shaft from the t-case was too short to seal the automatic transmission's output shaft.
