 I purchased this jeep because i was told it needed a transmission, these are the symptoms, when you first start the truck and you put it in reverse, the engine kills. you start the truck up again and put it in reverse, it vibrates and the engine wants to die but the computer tries to increase the rpm to prevent it from dying, you then have to apply the brakes hard, when you put it in neutral, the rpms are at about 2000 and then they come down. when you try driving the car forward it has a vibration and when you are coming to a stop, it does not want to stop, its as the computer is reving the engine like it does in reverse. i have had the transmission rebuilt and it did the same thing, they have taken this transmission out 4 times, changed everything in it 3 times, got another transmission and put all the new parts in that one and still the same problem. i replaced the tcm from a same year grand cherokke, had the dealer flash the computer and still the same, had the try to diagnose it and they thougt it was the map sensor, because of the rpm problem, i changed it and still the same problem. after all these changes, the truck now runs fine for a few minutes, but when it warms up, the same problem occurs, im not sure if thats because the wheather is cooler now. i have so much money tied up in this truck and besides this problem, the truck is in great condition and runs great, can somebody please help me.

 My jeep grand cherokee is 2-wheel drive and is not taken off-road nor otherwise driven abusively. despite this i have had four (4) engine mount failures since i purchased the vehicle. some of the failing mounts were mounts that were previously replaced. in addition, the failed engine mounts have caused other damage to the transmission mounts and other engine parts which i have had to replace. the maintenance tech at lithia jeep informed me that the engine mount failures were a common problem but wwere not addressed in any recall or internal chrysler communication to the customers. i would like to have my replacement costs associated with the engine mounts and related repairs returned and would like to have improved engine mounts installed.

 Beginning spring of 98 vehicle began to stumble-ever so slightly. by late spring it was cutting out. this was at about 50k. i had it tuned up. the problem continuted until it began to actually stall, especially at high rates of speed. it would always restart-in park-right away. this progressed to stalling at any speed and taking longer and longer to restart. on one particular trip this spring, we ran down the battery trying to get it started and were sold a dealer battery, to fix the problem. two blocks from the shop it stalled again. it has been in one shop for a week, and another on 3 separate occassions. the last visit was for battery cable clamps and a fuel filter. well the next day i drove my usual 371/2 miles to work, 12 hours later i went out started it and drove about 6 miles, parked. half hour later, it would not start. after 1 3/4 hours later it started, 5 mi later stopped for a light and it stalled, in the middle of the stree for 1/2 hour. it started and i had no problems the remainder of the miles home at 70mph. there is so set speed with these stalls or warnings. recently it restarted itself, as i was coasting to a safe shoulder area. now it's parked again, i'm very afraid to drive it anymore. please help me find the problem. thanks pat m. *ak

 Wow, it's very amazing to me that there are so many v6 grand jeep cherokee's hat have cracked exhaust manifolds. we love our jeep's, we are the owners of our second one. this is under the jeep where the exhaust and emissions heats and and cools. the jeep sounds like a hot, hot rod. (i'm not in that age bracket anymore). this manifold is so common now that your local pep boy's, david early tire etc. (small shops) are stocking them?they use to be a factor order item.*ak
