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? | |

Replying to: cbshark (Oct 22, 2009 6:50 am) 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. |

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?

Replying to: 99jgcl3 (Oct 27, 2009 7:52 pm) --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? -- |

Replying to: 99jgcl3 (Oct 27, 2009 7:52 pm) 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
