#909 of 1066 transmission not shifting by boydscove

Jan 05, 2012 (8:50 am)

Hi, I don't know if anyone has had this happen before so here goes. I own a 2002 Jeep Grand Cherokee Laredo with 176,000 kms. Lost the reverse and just before that when you stopped at an intersection and than tried to accelerate, the tranmission was not dropping back into first and is trying to start off in third gear. Took the vehicle to a transmission shop, had the reverse replaced and than he took a look at the shifting problem. Governor sensor was replaced twice, wiring harness has been replaced. They said it was the computer, took the vehicle to the dealer and had another computer programed and put into it. Codes still show that the governor sensor is the problem. Advised to return vehicle back to transmission shop to be fixed. Still have the same problem. Is there anything else that can be done?

#910 of 1066 jgc transmission "thumping" by 7657

my 2005 jgc with 80K miles makes a thumping noise when automatically switching between gears. once up and running at 60 mph on the freeway with no gear changes runs fine.

Have 2002 jgc, 4.7L, in the last year or so, when engine starts up cold, it revs high, 2 to 3 grand, up and down, and slowly drops rpm down;
if put into drive when engine revving high, then engine stalls;
if let engine idle and warm up; then engine still revs around 1 to 2 grand at idle; but car can be driven without stall;
  
cleaned control valve body, no difference;
took it to a mechanic, he checked with his alldata, says, the throttle control valve is bad; quoted $150 for part and labor;
after new throttle control valve, no difference;
 
mechanics says, the tps, throttle position sensor, is also bad, another $150;
now engine runs and idles smooth as silk; idling under one grand, no more high revving after start up, and no more stalling when put into gear;

Hi my 2004 Grand Cherokee Jeep has an intermittent fault, every week or so the Transmission sticks in first gear. I have to stop and then the fault is fine. It happens maybe twice in a journey, but only happens every 4 or 5th journey. I have had the fluid and filter change. it has 70k on the clock. Any advice.

I am SOOOO disappointed in Chrysler with this problem. This shuttering occurs at exactly 17 MPH in my 2011 GC Limited. They have rebuilt the entire valve body in the transmission, replaced the drive train control module and updated the software as well and I also have lost about 3 MPG!
 
I have spoken with Chrysler customer service a couple of times and they have told me that they have left my file open on this problem (supposedly that means that they are working on a fix), but nothing yet. The dealer said that they have this with all the Limited models and offered me to drive others (I really don't care if the trucks in their lot shake, rattle and roll --- I just want mine fixed) to feel it for myself and they told me that the cause is that the torque converter is engaging at that speed and this is the cause -- If this is the cause it can be fixed and I think I am being told a load of crap so that they don't have to have a recall and replace all the transmissions in this model (which is something that they have done with overseas models)
 
As an aside, if you change the drive control between the seats to SPORT vs AUTO, this will cause the shift pattern to change a little and it won't be as noticeable, but that damn vibration is still there ...
 
LET'S GO CHRYSLER, these are $35 - $50,000 vehicles that you make a ton of money on --- If you cannot afford to get this done right, have FIAT give you the money to fix this problem correctly NOW!

Make sure there are no fluid leaks. It affects the pressure. Pay special attention to transmission cooler lines. They should be bone dry.
 
Next, check all electrical connections between engine and transmisssion. Make sure no wiring or connectors are contaminated with oil. Sometimes the engine leaks oil and it blows back over the transmission.
 
If you don't find anything, then I think you have an electrical-mechanical component like a solenoid inside the transmission with an intermittent fault. Unless somebody can diagnose the problem, you will have to do a rebuild.
 
If your transmission has a computer, check with the dealer about any Tech Service Bulletins or firmware upgrades.
 
Transmission problems are the worst.
 
Once you fix the problem, please update the post

Hi Iam having the same problem only worse it is now stuck in crawl and wont advance through the gears. have you made any progress in diagnosing the cause as where i live it is going to cost a fortune to get it to a garage that can diagnose the exact problem. the OBD codes that show up are P0700 and P1652

Try Dr. Tranny's Shudder Fixx. It is awesome. I buy it inexpensively off eBay and put it in all my vehicles. I have a 2003 Ford Windstar company van - that model of which is known for transmission torque converter issues. Dr. Tranny's has stopped the issues with my Ford and both my Jeep GC and Commander rough shifting. The company responds quickly and thoroughly to any question you have about their extensive and unique product line. Dr. Tranny is perhaps the best kept automotive secret. I learned about it from a transmission expert.
