We took the Jeep to Orange County Transmission. After a test drive, the problem was deemed internal, with the shift rail the prime suspect. The company doesn’t like aftermarket rebuild kits, as they are often missing parts or don’t quite fit right. We got a genuine factory rebuild kit thanks to a good parts guy at our dealership who tracked down the elusive PN R0035503AA Mopar rebuild kit. It includes all the internal wear items as well as seals. Armed with that part number you should have no problem finding a rebuild kit of your own.
