    The tranny worked great for about 6000 miles and now is starting to shudder again and the surging in the engine is back also - - Talked to a woman who had an identical 05 JGC as mine and was told that she hadn't had any surging problems with this jeep but this was their 6th jeep and some of the other did have that problem. Jeep knows that they have a problem but will not admit to it seeing as other units also have the problem . Well , Chrysler will be out of business before long and then we'll all be screwed . . . :sick:

    if you had the rebuild done on 10/15/08, you should still be covered under warranty for the transmission. did you have the work done at a dealer? most places give you a 12 month/12K mile warranty with stuff like that. good luck.
  • My husband and i checked our brake fluid the other day and it was black as all get up. i have been having problems with the brakes not engaging untill the pedal is almost to the floor. i have an 88 jeep cherokee. i don't know when it had a fluid flush last i have only owned it for 5 months. if i have been driving a while the brakes start to get mushy and start to studer, but other wise the are just slow to react. i had them inspected 2 months ago and they where fine. i am not leaking around the master cylinder or anywhere else. i had one tech tell me that it sounds like i have an air leak in the line, but at the same time i had another tell me that changing the fluid will fix it. PLEASE HELP!!!!! just the flush is fine, but if i need a new master or booster i am screwed because i have a baby and i have to take my husband to and from work.
    thanks--paganmomma :confuse:

  • My 1999 Jeep Grand Cherokee does nothing. The engine doesn't even turn over. The odometer comes up with the word "done".

    The last time the engine started, it ran for about 2-3 mins, made a muffled thud noise and just stopped. It hasn't started since. Does anyone have a clue as to what is going on? Did my engine blow up or something? What does "done" mean? I'm at a loss.
  • My jeep burns up the coils in about a day. I have replaced the plugwires and the plugs. Rotor button and dist cap. I have also replace the ground wire to the block.
  • what's the mileage on it? i also have a 99. it's never been flooded...has it? how long have you had it?

    My 2000 Grand Cherokee rear rotor was frozen in place. I could not get it off due to limited work space around dust/splash shield. I did google search & found a site with pictures and how to break free which I wanted to share for all diyer's, Patience needed but this simple method worked for me. Another good reference site for JEEP info is

  • Just bought an 03 2.7 crd, heated seats and all that flash ,But here in north ireland its still a bit nippy this time of year ,so it would be nice if the heater worked as well .The AC works ,the blower works on every level ,but blows cold air ,jeep temp is normal ,I would be most grateful if someone could point me in the right direction as my kids love it ,but my wife wont warm to it .no pun intended.

    I had the same thing happen to my 2000 JGC and the problem was I need a new battery

    Before you invest in a new battery---disconnect the negative cable first the positive cable secondly---clean the batt posts and the inside of the cable ends till they are bright. R econnect the pos--then the negative to the batt. Get in the vehicle--put foot on brake and hold--Turn the ignition switch on-off, on-off, on-off. release the brake and start engine.This has worked for me on a 99--4.0 L engine.

    did you ever figure out the problem with the intermittent stalling ?
    I have a 1997 jeep grand cherokee limited, and I am having the same problem..
    Any suggestions ???

    I have replaced the battery, the Distributor Cap, rotor and the pick-up coil. It ran fine for 1 weeks, not one single problem. Then one night about 5 miles from home pulled up to stop light and the jeep just died. Ever since then the problem has gotten worse to now we can't drive it at all.

    Any suggestions ???

    Try the coil pack and spark plugs? is the engine souding ok? does it miss fire? my problem with the jeep was to do with a switch on the driver side window. Once this was fixed, the car worked fine. Do you have other problems?

    I have a 2003 4.7 jepp grand Cherokee with a 601 error. The Jeep runs fine. I replaced the ecu and the new one, after being reset, started one time then develope the same 601 error. After all resets it last only one start. The jeep has has been running fine, with this error, for a year. It acts like there is a virous that keeps reinfecting the ECU.
