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.

2001 T & C Transmission problem thud when it down shifts by hunterbaye

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?

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.

transmission jolts and "check engine" light came on by 99jgcl3

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?

Make sure your shift level cable is not out of adjustment. Over time I think it stretches. If cable is out of adjustment, you think it's in drive, but it's actually 1/2 way between neutral and drive. I suggest you ask your mechanic. I thought it was hard to do without a lift, but it's not impossible.
 
The transmission interacts with the engine (controls, sensors, etc.). Look for problems here. Their repair cost is low compared to transmission repair. Check the fluid level HOT. Low fluid can cause all kinds of symptoms. I made this mistake once. Good Luck
