Thanks for the info and I totally agree with your comment about being mistreated by Customer Care at Jeep--at one point, the service agent just snapped at me on the phone, saying "What are you even expecting? What do you want?" when I kept pushing for some kind of a response. I will check into the link you sent about grounding the battery better, but it is frustrating that this should even be done, especially because the Jeep already has two grounds that the dealership assured me were in perfect working order. I will continue to post if I find out anything new; best of luck to you.

Did that end up fixing the problem for you? Can you tell me that after the hard shift and the noise, did it ever trigger the check engine light to come on? I think I'm having a very similiar issue with my 2006 Grand Cherokee, and I've had it in the shop twice now without any luck. Two differnet transmission sensors have been replaced and the check engine light just came back on. The dealership has offiicially had the car more than I have in the past three weeks.

My 2011 Grand Cherokee Limited with V6 also has the lurching forward while in park problem. It is intermittent and I have been unable to reproduce it at the dealer.

My 2012 hemi GC overland is doing the shudder thing when trying to accelerate also. This motor should easily pull up a hill in 6th or 5th but when I give it a little gas it feels like it shudders and won't accelerate unless I really give it gas. At highway speeds when I try to over-take another vehicle, very little gas should be necessary but I have to move the accelerator a lot and it shudders before it goes. There is no throttle response at all. This is not acceptable for a vehicle with this much torque. Dealer reflashed on first trip there last Friday. Took it back today, 9/4 and their test equipment can't find anything. Service manager will not acknowledge the problem but I am supposed to get a callback tomorrow. Tested another 5.7 and it does not feel like this.

Hey David, I have a 2004 Overland Limited edition with the same problem. It will drive fine and then randomly the RPM will go high then catch itself and of course turn on the check engine light. I went to one place and they said my computer is going bad and I need to replace it. Thats about the only thing I can think to do. But I saw your post about the ground wire from the case to the battery. Exactly how would I do that. If that works great, if not looks like im ganna "try" buying a new PCM and see if that will fix it and get the dang check engine light to turn off.
 
Oh and btw mine is not the hemi, its the V8 4.7

#1017 of 1066 Transmission stuck in cold weather by sophia8

Sep 24, 2012 (1:16 pm)

I have a 96 Jeep Grand Cherokee. Whenever it's cold out the transmission usually gets stuck whether going up hill when stopped then rolls back until you rev the gas up to catch. I have the same problem every winter. Even backing out when it's cold out it will get stuck until you rev the gas up hard. I've had the RPM reset as it used to want to stall out on me last year and I believe the teansmission fluid was changed last year to no avail. Can someone pls shed some light. Thank you

A few weeks ago I was driving down the highway at around 70mph, and the car shuddered. I actually thought I’d run over something in the road, but there was nothing there. A few minutes later, it happened again, coming out of a speed zone. In the next speed zone, while slowing down, I noticed the car slowing down more quickly than normal, as if I were in a lower gear. I then realized the engine rpm was about 1k higher than normal. Pushing the Overdrive button had no effect on anything. I pulled over and shifted into Park and then back to Drive. When starting out, it felt like I had no power, almost as if the transmission were slipping, but the engine wasn’t revving high like it should when slipping. I parked the car upon arrival at our destination, and then test drove it a bit later, and it was fine, and pressing the OD button had a normal effect on the engine/tranny. On the drive home, it shuddered again, twice, in quick succession, but drove fine the rest of the way home, just at higher rpm (3200rpm at 70mph, or 2700 at 60). Over the course of the following few weeks, it happened intermittently, and nothing environmental seems to affect it. It happens when it is cool, when it is hot, when it is dry, and when it is wet. Sometimes it will happen when I’m driving down the road, and sometimes it will happen from a dead start, without the shuddering. It seems as though I’ve lost the highest gear or two. Sometimes it will only shudder once, and the engine rpm is then higher, but not as high as when it shudders twice. I have found that when it happens, I can pull over immediately, shift to park, turn the car off, start it again immediately, and it is fine. This seems to indicate to me that it is something electronic that is not allowing the transmission to shift properly, or causes it to lose its ability to remain in the highest gear or two. Of course, I’ve checked the fluid and it is fine, not burnt smelling, and filled to the proper level.
 
Any suggestions? I’ve already talked to one shop, and they didn’t seem to know exactly what it could be, but immediately went to the option of replacing the tranny…something I’d like to avoid if this can be fixed by replacing a part. I’ve done a little reading, and one possibility seems to be the Governor Pressure Sensor. Another possibility might be the TCM?

By no means am I a expert, and HATE going to body shoppes because they LOVE to tell you to put in a new Trany, and good bye $$$. I went to Good year and paid for them to do a inspection (which cost $30-70) depending on specials etc. They went over the whole car (TRYING) to find what was wrong so they could have a reason for me to do business with them. At the end they found nothing wrong with the engine. (so they didnt charge me) so I was able to rule that out. My next step was to go and have the computer codes checked. Turned out my PCM (which depending on model is where the TCM is) was going out which was why my transmission hated me. . They tried resetting it, but would error out again. So my end result (for my issues with transmission) was to order a new PCM. Find a good retailer that backs their work and can get it done for around $200. and you can install it yourself.
 
Again I am no expert, but going both of those routes helps identify the problem to know where to start without having to go to the dealership and take out a loan to get it fixed
