Heres an update from Jasper engines And Transmissions web site about what fluid to use in Jeep T5 transmission.
"TO PREVENT HEAD SET BURN UP WE SUGGEST USING A MULTI-GRADE CE RATED EN
GINE OIL INSTEAD OF A.T.F. "
Just thought I'd spread the word !

Yeah, I don't know about that one. I used 90 weight gear oil in my T5, that's what I planned on usind, and what everyone told me to use. Try it and tell us how long your T5 lasts. As for me, I'll stick to my 90 weight![addsig]
borg warner suggests ANY of their new or rebuilt manual transmissions to be broken in for the first 10,000 miles with ATF... then synchromesh fluid there after[addsig]
look for it at autozone, pennzoil makes a version of it, yellow bottle... some say driving a vehicle with synchromesh fluid in the transmission is better than sex[addsig]
