#175 of 1066 2002 Jeep Grand Cherokee and Transmission Problems
May 06, 2008 (10:15 pm)
Hello! I have a 2002 Jeep Grand Cherokee (67,000 miles) and for the last 2 weeks or so the following things have been happening:
1. When I brake to stop, say at a stop light/sign, just as I come to a complete stop, the entire car jerks forward a bit even with my foot on the brake. This happens EVERY time I stop. The jerking/lurching action can even occur when I have been at a complete stop.
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.
I took it to the dealer on Friday and they told me that it was not an electrical problem, might be internal and recommended a transmission flush, etc. I took the car to a mechanic friend on Saturday and he did the flush, cleaning, whatever it is for $125. He told me the fluid was so dirty it looked like motor oil. However, now I hear something like a fan squealing while I am slowing down to stop. This is very annoying!
The car did improve slightly that day, but the problems are back today. Does this sound like the entire tranny needs to come out? I am a single mom and the $1500 isn't growing on the money tree in the back yard today. HELP!
Thank you for any advice you can offer.

My problem is that my trans is stuck in safe mode. I have been running it and was curious if the 4x4 still works. I took it off road and that 4w lo works fine but, it now won't come out of 4w lo. how do I get it out of 4w lo? I know I need trans work but 4x4 did work before it went into safe mode.

According to the Haynes repair manual the code is (No distributor reference signal detected during engine cranking. Check the circuit between the distributer and the PCM.)You'll need a meter to do this. Some places do free scanning and can verify the problem.

I have a 2005 GC with 5.7, your issues sound very similar to mine. The dealership has gone back and forth to whether it is an engine or transmission, although like yours they did replace the torque converter once but that did not help.
Have you had any luck getting this issue resolved?

Bought a used 98 Cherokee a couple of months ago. It is now leaking a small amount of oil out of the transfer case. Before I take it to our mechanic, Is this usual with this model year? Thanks.

OMG!! What was the out come of this problem you had?? My Jeep GCL (05, 44k) is doing the same thing...the clicking in the steering, and the gear thing...but it hasn't started stallling on me yet.

I bought my 91 Grand Cherokee Laredo 6cyl last year, it took off in 3rd gear from a dead stop pretty randomly from the time I bought it. It's gotten more consistent over the year and jerks forward at long stops, so I talked to a transmission guy, who said it needed a $250 valve replacement. When he got into it he found much metal and a snap ring so he rebuilt it, which was $1400. It took 4 days of me driving my normal 8 miles to work before it was taking off in 3rd gear again and jumping forward at a red light like it's shifting down (not shifting down to take off in first gear of course) it is probably worse than it was.
I tried the trick of turning the key off an on three times to have a code revealed to me, which only gave me the word 'done' on the odometer. The O/D light didn't flash at all. Now I'm searching the web for a solution before I start replacing sensors, racking up more money. Ideas?

I continue to have rough idle and vibration. I have verified the engine is not running correctly. First, I plan to verify the engine should be operating within tolerance. Then, I will look at possibility of transmission knocking it off blanace.
My situation is a bit different (year 97, 4x2) unless you put 130K on yours. I'm fixing it for my kid. I would consider a transmission rebuild if I get engine running OK. Otherwise, no $ for dealer or repair shop.
See below for details and Good Luck.
The engine has rough idle when stopped. Putting transmission in Neutral reduces vibration, but it is still way too much. I have no Check Engine Light. There are no codes (you can get them via the odometer). Otherwise, acceleration, ride, and steering are still very good. A/C great, but I'm on my 3rd radio.
Haynes makes a great manual about OBD II. It has a lot of useful info about what to do before buying a scan tool.
I purchased a vacuum gauge. It looks OK. I purchased a fuel pressure test gauge. Mine is suppose to be about 45 psi. At idle, my pressure vibrates between 35 and 42. I open the throttle and it locks steady at 42. Then the engine sounds great.
I was surprised to learn there is a cable between the transmission and the throttle. So far I have found little info about how the details of their interaction. I have the Haynes and the big Chrysler shop manual.
Below is a list of servicing I have done. I believe all of them have helped.
(1) Change transmission fluid and filter. Adjust forward band.
(2) New distributor cap, wires, spark plugs, coil and air filter.
(3) Pulled fuel rail. Injectors pass electrical test
(4) Intake manifold vacuum test OK
(5) Removed & cleaned throttle until it looks new. Replace idle air control valve.
(6) Problems detected with fuel pressure test as explained above.
Note: Fuel pump module looks like it is connected directly to battery voltage and is gated on/off by the fuel pump relay. So why isn't it the fuel pressure the same all the time?

Thanks for the info. I caved and brought it to the dealer again. The dealer said I have a new kind of transmission. Its electric or something. The transmission is designed to "lock" between gears to "save fuel". I don't know a thing about cars but that sounds like a crock. I was figuring it was some kind of injection problem. They did a computer update and it drives a little smoother. Weird. I still will not settle until I find a better answer. Thank you for your answer. I am going to run it by another private party mechanic.
