Mea Culpa.

I took my '97 TJ to the Jeep dealer to get an erratic oil pressure issue
fixed. They replaced the sender, but I haven't driven it long enough to
know if it solved my problem there.

While it was in, I had them change the automatic transmission fluid. I am
driving 1,200 miles to Moab soon for some 'wheeling and I wanted the tranny
in good shape. They put in ATF+4. The manual calls for ATF+2. ATF+4 is a
synthetic while earlier versions were mineral oil based. I read somewhere
that ATF+4 can degrade seals in older tranmissions. Does anyone have real-
life experience with ATF+4 in a pre-99 TJ automatic?

'97 TJ
'93 XJ
'79CJ7

 

Wrong ATF+4 is fully synthetic and there is a TSB out that ATF+4 basically
replaces ATF+1,2,&3
