One what year is the jeep? Two, on the tranny, there is a tranny speed sensor. This sensor on chrysler made trannys are notorious for going out, my 99 Dakota (which uses the same tranny the XJ's and GC's use, and I think the auto TJ's as well) had it go out last year. It wouldnt up or downshift automatically. The sensor was 50$ and took me ten minutes and an adjustable wrench to change. If I remember correctly it was on the passenger side of the transmission, but I might be wrong... JMTC
