#1028 of 1101 1996 Jeep Grand Cherokee Trans shifting problem
Oct 18, 2012 (7:15 am)
I have a 1996 Grand Cherokee Limited with the 5.2 V8 and 4 speed automatic transmission. This vehicle has been great for me and trouble free, until this past Monday.
I live in PA and had to drive up a road which included a 3 mile drive up a mountain, and down the other side. i noticed while climbing the mountain the rpms were at 3 grand and the trans did not shift up out of 2nd gear. i had reached 55 mph and it should have shifted to 3rd gear or Drive. i disengaged the overdrive and let off the gas then it shifted. I thought i must be low on fluid. so i was careful coming down the other side of the mountain highway and checked the fluid. it appeared low as i did not see fluid on the dipstick. i added fluid and continued on my way to Allentown where my daughter was going for surgery. i noticed that every time i came a stop the transmission would again not shift out of 2nd gear unless i let off the gas, or shifted to neutral then back to drive. if i pulled out very slowly from a stop it would shift some of the time.
when we reached the hospital my son -n-law and i checked the fluid again and it again appeared low. the fluid is clean and not brown, and there is no burnt smell. we again added fluid. and left it at that. when my daughter was out of surgery and okay i decided to head home, and her husband would stay with her until her discharge the next day. ( They had followed me in their own car). Again at first the trans shifted normally. then the same symptom started again. i made it home by repeatedly shifting to neutral then back to drive and the trans would shift in to higher gear, until i came to a stop again.
when i got home, i again checked the fluid, and again it appeared low. so stupid me, i again added fluid. I did not run the jeep again this day, but noticed a few hours later that i had a nice leak of trans fluid that appears to be coming from between the trans tail shaft, and the transfer case. the fluid is clean and un-burnt. i checked the fluid level and found it was way over filled. since i have an external cooler i was able to drain away the extra fluid. with the fluid level showing normal, with the trans hot in neutral. the leak appears to have stopped as i had wiped off the area where it had been dripping and placed cardboard underneath, and only a few residual drops were there. i test drove the jeep again. and again the same symptom of not shifting to high gear appeared.
I was checking forums here and some are saying it is a problem with the throttle position sensor, i have a new one ordered and will replace it. i am hoping this is the problem. I need and would greatly appreciate any and all input from you jeep guys and gals, as although i have mechanic experience, i am not up to speed on these newer systems of sensors and relays controlling transmissions. i am retired / disabled with spine problems so i am on a fixed income, and i can only do minor work myself. Please post if any of you can offer any advice or help. God Bless and Thank You!!

This is an update to my prior post. today 10/18/12, i went to get gas and to try a bottle of K&W Trans X. i drove the six miles to the NAPA store and the shifting problem seemed to have gone away.
They were out of the small bottles of Trans X and not wanting another episode of over filling, i decided to return home. By now the jeep was fully warmed up. and sure enough it started again, only this time i no longer had second or drive.
When i pulled over to the shoulder and put it in park for a minute or two, i could again go with first second and drive, with drive fading out and it beginning to slip until i manually shifted into second.
I noted that the problem was at worst when the overdrive was engaged. so i kept the overdrive off. this helped a little but i ended up making it back home using only first gear.
I again checked the fluid. it is right at the full mark and a pretty pinkish purple. no smell of burned fluid, no brown fluid. I am totally lost at this point. ANY HELP WOULD BE GREATLY APPRECIATED!!!

I have had a similar problem with my Jeep Laredo CDR 2003 since March 2012 and to date have not been able to fix it. Since March the vehicle has been back to Jeep 4 time with the same problem of going into limp mode. Each time they have fiddled with it and all is OK for about 4 - 6 weeks. At this time it is still at jeep and they inform me that it requires: Valve body & TCM all up including labour $7,276.05. They say that the codes come back as supply voltage to the TCM so I don't understand why tehy need to replace these parts.
Do you think that I may also have a grounding problem?
Hope you can help.

That price is insane. The TCM, if I'm not mistaken, can be had for $100.00 or so. The entire transmission can be had for less than 1/2 that price. I'd take it to a good transmission shop.

My 2012 Overland with the 5.7 Hemi is shuddering at Highway speeds every time i come to an incline. I have tryed to see if cruise control changes anything, but no luck. The only way around it is to go back into manual mode and raise the RPMS. Just yesterday I went and complained to my dealership for the second time. The first time they ran the diagnostic , and told me no issues were found. So this time I insisted on taking the service manager out on a drive. On the drive he did his best to educate on how the vehicle is designed save me money.... switching to 4 cylinder mode whenever possible. I myself continued to educate him that for the money I payed, this was not acceptable. With the service manager driving, we approached an incline, the vehicle hesitated right on cue. Back at the dealership we scheduled yet another diagnostic appointment.
#1035 of 1101 Jeep Grand Cherokee poor performance in snow and rain
Nov 07, 2012 (4:34 pm)
I have a 2001 Jeep Grand Cherokee Laredo that I've been driving for about 4 years, all year-round. Up until the end of last winter, I had no problems driving in most weather conditions, from heavy snow to ice; for the most part I only needed to use the four wheel drive in the worst conditions. However, mid-winter last year, my check engine light came on, and I brought it to the local garage. I found out that I had to get my torque converter replaced, which I did. From around that time, I've noticed that the jeep seems to have a lot more trouble "gaining momentum" from a complete stop, and driving smoothly through relatively docile conditions. Many times, I've come to a stop sign, and tried to slowly start moving again, which always worked in the past, but it still seems to have trouble getting traction (or something; I really don't know much about cars). This includes instances where there is much less than a quarter of an inch of snow, and little or no ice, and cases where it is raining. To my embarrassment, there have been a few times where other cars go by me with ease as I try to get through conditions that I believe I easily could have gotten through in the past. FYI the tires have all been replaced and are of good quality, so I've been assured that it's not likely to be due to worn out tires. I'm planning on asking a local mechanic about this problem soon, but I'd appreciate some second opinions. There have not been any major snow storms since I got the torque converter replaced, but I am worried that the jeep might get stuck even with four wheel drive on, if anything more than a mild storm comes through (and this is new england, so it's expected, although last year we had a VERY mild winter).
P.S. I'm sure this is related in some way, although not directly, but since the torque converter was replaced, the jeep seems to have some problems switching gears. Instead of shifting from exactly 1 to 2 or 3, the rpms indicator seems to hang a little bit lower or higher, and shifts at weird times. Also, most frighteningly, a few times when I've tried to accelerate quickly, as in going onto the highway, the jeep went straight into the red area of the indicator and stopped accelerating. I've been trying to save up money to get this looked at and maybe maintenanced again.

Hi there, I know this was quite a while back, but did you ever find out why your jeep was having trouble moving from a stop? I seem to be having similar problems in snow/rain conditions, although I don't have any of the problems you had with four wheel drive.

":2. After coming out of a stop, or even putting my foot on the pedal after slowing down, it has a hard time grabbing the gear and getting out of first and the engine strain is very audible. Once it shifts out of first, I have no problems.
Hey there. Did you ever figure out for sure what was causing this? Any feedback would be appreciated!
