  • is it possiable to just have a something wrong where it won't hold fluid, i pushed it back and noticed fluid on the ground, where it was parked. so if its not holding fluided could that cause my problem

    yep !..automatic transmissions burn up REAL QUICK when they'r run low-or out of fluid..that's why they put a DIPSTICK on them !..
  • 2000 GC Limited, 4.7L. When sitting at a traffic light, my transmission will bump so hard that it feels like I've been rear ended. Also notice delays when shifting to R or D, and occasionally it seems to be hung up in 2nd gear when pulling away from idle. I need help fast, it seems to be getting worse. Fluid levels look fine, clean (light pink). I've read enough here to hope that it may be the TPS, solenoids or a cable. Really hoping to avoid the high price of a rebuild. Not afraid to get dirty, but I need direction. Any clues? How do I check the TPS? What am I looking for?

    how long a go that you changed oil could be filter part pluged
  • 2300 miles ago. I'm close enough to 3k that I'll go ahead and change it if that's even remotely a possibility. Change the transmission fluid/filter too?

    My car stops for no reason when I decelerate to turn corners, enter an on-ramp to get on the highway. I bought it with 46K miles and it now has 68K. What do you think this could be? Goodyear couldn't find anything when I took it to them twice after it stopped. When it starts up again, it runs fine until it stops without warning...The steering wheel just locks and I know what's about to happen.

    What do you think is happening?

    do you mean that the steering gets hard to turn?

    or does the steering wheel lock and not be able to turn?
  • Is it possible to change a 249J transfer box to a 242J on a 1994 Grand Cherokee Limited?

    If so, are there any modifications needed on the new box?

    If you have 4x4 I suggest you evaluate the transfer case to make sure it is not causing or contributing to the problem. If you've never dropped the pan and changed filter, you can try that first.

    Suggest you evaluate engine (compression test) and then decide on transmission. Remanufactured trans is less risky than rebuild but I don't know the costs. I had a trans rebuilt by a Dodge dealer, but it was their car and their extended warranty.

    your trans has no cables all controled by computer

    in engine compartment on the left side when you look from the front way to the back right beside what looks like a thermouse bottle you see a large bunch of wires hooked into a box have found that the conection will get loose and allow water from the acculmater to enter and crode the conection (i unhooked the battery and took the conection apart and pluged and unpluged a few times then coated with dilectric greese put back together took care of my rough shifting on my 2000 jeep gr cher
  • light pink transmission fluid means it's contaminated with water. you should stop driving the truck and see if you can't flush out the water from the system. transmission fluid should look a clear red even as bad as a dark red with addative. black means it's burnt, but pink is water, and most likely a transmission rebuild. I'm stuck in the same situation, but mkine is older and won't shift out of second. hopefully i helped. bring it to a tranny shop and let the pro's deal with it.
  • Just had a Complete Transmission Flush ( $380) at a Chrysler dealer
    and when driving home the transmission makes a Thud/Clunk noise when coming to a stop. It will not do it when I put it in netural- and if I stop when going less than 30 MPH. Any suggestions.
  • '93 Jeep Grand Cherokee Laredo. Tranny pan seal was leaking, had it replaced and tranny flushed. Still leaks! I was driving and lost all power to the wheels. Has plenty of fluid. Transmission Control Module bad?
  • loosenutloosenut Posts: 165
    first,$380 is a high price for a trans flush/fill-i called aamco,and their regular price-for my gcl,was $120..with the synthetic fluid,
    --so,-take it back to them,and see what they screwed up..
    --then again,sometimes things break when you fix other things..could be totally unrelated,but because they happened just after you had something fixed-maybe the other parts got jealous?(lol)

  • ***UPDATE***

    After reading all of your suggestions, I figured it'd be worth it to drop the pan, change the filters and fluid and test the solenoids. I didn't have to go that far. When I crawled under the Jeep to get started, I found the cable that runs from the driver's side of the transmission to the gear selector in the cabin loose. I don't know the precise name of the parts, but this cable moves a lever on the side of the transmission when you select P,R,N,D,1 OR 2. It wasn't connected at all, but was simply laying next to it's connection. It's just a rubber boot on the end of the cable that pushes over a ball pin type of connection. I pushed it back on, had my wife turn the key on (but not the engine!) and go through the gears while I watched from beneath. Everything looked fine, so I test drove it and am happy to report that so far so good!!! No more delay when putting it in gear, no more rough downshifts at traffic lights. I'm curious to know how the thing was moving at all without that cable connected, but I'm assuming the computer can recognize the position of the gear selector and was doing it's best to handle the shifts accordingly?

    In any event it works! Thanks for all of your suggestions and tips.
  • Your problem sounds similar to mine. Check out message #415. I found a shift cable on the driver's side of the transmission that wasn't connected on mine. Pushed it back and so far I haven't had anymore issues.
  • I have a 99JGCL and lately while I'm driving it seems that the transmission uncouples for a quick second then re-engages making my car jolt. Sometimes it does this 2 or 3 times in a row. The engine is still running and nothing seems to be nothing wrong with it. It is like I'm switching from D to N and then back in D really quick. Today is did it really bad, about 3 times successively and more pronounced then before and during one of the jolts the "Check Engine" light came on. I made it home without any other problems, shut the engine off but when I restarted it a minute later the "Check Engine" light was still on. I cannot correlate this to temperature, distance, time of travel, or anything else, it's never consistent.

    I don't need to drive the car for another day so if anyone has any suggestions in the mean time please let me know. Most of my driving is on highway and this is worrisome. Another thing, (I've had this problem for some time) from time to time it seems there is a lag in the gears shifting. For example I'm coming to a full stop and anywhere from 1 to 3 seconds after I'm at a full stop the transmission shifts into the low gear. No problems shifting while accelerating or slowing down, this happens only when I come to a stop, i.e. red light. Are these 2 problems related?

    seems to be a reocuring problem with that series of drand cherokee laredo-those german designed-american components and workers..my-98 has been pretty good so far(knock wood)..
    --check some of the previous posts about tranz troubles..
    --seems the connector that controls the shifting-cause it's all eletronic-to shift from drive to park..
    --aparently, one cure is -find the eletrical plug that goes to th trans..unplog it,and look at the contacts..-break out out your trusty swiss army knife-scrape the contacts clean, put a glob of dielectric grease in there-to keep them from corroding yor contacts again--put it back together again,and give it a shot?
