 I have a 2000 gmc jimmy 4wd. it has a hd towing package. at 84,300 miles my 4le60 transmission went out. the sun gear went bad. the sun gear is the main gear in the transmission. i have never raced the truck, or towed a trailer, or went 4-wheeling with it. i paid 1,400 dollars to have it rebuilt. by looking online it seems that this is a common failure to this transmission. what recourse do i have? *jb

 First the transmission went out and i had to have it rebuilt...then, i had to replace a ball joint...now the other one has to be replaced. the mechanic says it is too dangerous to drive. these repairs are not cheap and premature! prior to having the transmission rebuilt i had it put on the machine and it sent out several different codes that had to be corrected...nevertheless, we still had to replace the transmission...also, the four wheel drive gets stuck periodically. *nm

 I purchased a 2000 gmc jimmy with 34000 miles on it and at 38000 miles the transmission failed. the sun shell granaded as the service people at gmc dealership put it. now with 83000 miles the transmission did the same thing. is there something wrong with the sun shells? is anyone else having this problem. all of my miles are highway miles and i have all my maintanence records to prove that i do scheduled maintanence on my vehicle. i also do not abuse my vehicle and do not tow anything. i'll go broke if the vehicle requires a new transmission every 40000 miles. each time it cost approx. $4,000.00 to fix. can anyone help? thank you
 The dome override button when pushed four times within 6 seconds disables the automatic exterior lights, including the headlights!. the option was was not listed in the users manual. we were driving at night when i found it by accident while trying to turn on the dome light. general motors admits that this was overlooked and not included in the 2000 manual. it almost got us in an accident or possibly worse. if i found it by accident, sooner or later someone else will too. the next time, it might get someone killed. people who own these 2000 models need to made aware of this option. i suspect that this omitted option is not just limited to the 2000 jimmy and fear that it may involve many, if not all of the 2000 gmc vehicles which have this dome override button. dt

 At first we noticed the passenger side floorboards were very wet. we proceeded to look under the vehicle, since it had been raining recently. then we saw transmission fluid from the front of the transmission. to the rear drive axle. immediately the vehicle was taken back to the dealership. where the transmission pan gasket was replaced. then the transmission pump and o-ring.a passenger side door gasket was ordered that was determined to be leaking. while waiting for the door gasket to come in, it had not rained in two weeks, but the floor continued to stay wet.since it is very hot here we notified the dealer when it was taken in for the door gasket replacement. the air conditioning drain lines were blown out to correct this problem. *ak

 Many problems with this 2000 jimmy. bought it used from carmax at 18k miles on jan 2003, got ext. warranty, but soon after, front brakes need to be replaced, replaced by carmax for free, but 6 mos later brakes needed replaced. was advised that rear rotors and brakes were almost at end of life. 9 mos later, replaced rear brakes and rotors, not covered under warranty due to wear and tear, spent $450 as well as replacing serpentine belt and flushing break fluid, total cost $650. problems with sunroof started in apr 2003, it finally stopped working and was replaced at 43k miles under ext warranty, had to get new battery, noise in under carriage on drivers side, determined to be problems with hub bearings and idle arm, inner tie rod, all replaced under ext warranty, total cost would have been $750. *nm

 While on mycarstats.com i noticed other complaints in regards to my 2000 gmc jimmy jumping into 4 low. one person was told by the dealership this could not happen at a stop sign but it happens with mine a lot. the odd thing is we have noticed it happens the most frequently when the humidity is very high. if you are lucky enough to hear it switching you can try to continue moving and pushing the 2wd button frantically. if you aren't lucky enough to catch it, the vehicle has to be stopped completely, put in reverse and push the 2wd button continuously. other times vehicle has to be shut completely off?? i too agree there is a safety issue with this when you can't go any faster than 5 mph or need to put your car in reverse at a stop sign!!*jb

 While driving down the highway vehicle all of a sudden went into 4wd low, could not get vehicle out of 4 low, had towed to dealer, was found had a faulty 4x4 switch and module, had replaced three times, cause is water intrusion, i feel this is a safety issue when vehicle slows all of a sudden. *jb

 Vehicle goes into 4-wheel low drive when it is raining. owner took the vehicle back to the dealer, who did a diagnostic, and told the owner that there was nothing they could do. this defect would have to occur while plugged into the diagnostic machine which was impossible. *ak took vehicle to another dealership on 03/05/2005, they plugged in and no code found in the computer. they also said vehicle would not go into 4 wheel low pulling up to a stop sign. *bf *nm
