Hello all, I recently picked up a 1999 jeep XJ with 203K on it. Have done all the basic tune up procedures and fixed any leaks that were present. Running great. Recently however, I took the jeep on a 2000 mile road trip to Yellowstone out of Portland Oregon. I noticed on this trip that when climbing hills and when strong head winds were present, the transmission would shifting between gears rather quickly a few times until it eventually decided on a gear. Cruise control also doesn’t seem to work anymore, but I’m not sure if this is related. Recently replaced TPS so I don’t think that could be causing it. Jeep shifts and accelerates find in street driving and has never slipped in any scenario. It is also worth noting that the highways on the trip were mostly 80mph which I’m not positive the transmission is happy with when it comes to picking a cruising gear. Lastly, my transmission fluid is clean DEX/MERC and is to the proper level (maybe a hair over the max mark on the dipstick). Any thoughts?
