2001 Silverado. . . . . My only problem with my truck is the service 4wd light. The problem is the electronic transfer case shift motor. The part runs a little over $100. I can't afford the part right now, but it doesn't affect my daily driving, just when I need 4x4 which isn't often living in oklahoma. Still runs and drives like a brand new truck.
Consumer purchased a brand new Chevrolet siverado. After about 1500 miles vehicle developed a popping noise in the transfer case. Consumer took the vehicle back to the dealer, and was informed that vehicle had a history of this problem ranging from the 1998 to 2004 models. However, this vehicle was out of warranty, and dealer and manufacturer were not willing to assist consumer with this defect.
Theconsumer noticed fluid leaking underneath the vehicle. The vehicle was taken to the dealer. The dealer informed the consumer that the problem was a crack in the transfer case and it was not covered under a recall.
The vehicle's transfer case failed. Upon further inspection the dealer located a hole in the aluminum case. The hole allowed fluid to be discharged which meant the transfer case could not be rebuilt.
I have 2001 Chevrolet 2500 hd 4x4 crew cab short box, with a 5 speed allison automatic with push button 4 wheel drive on the dash. At 117,000 miles my transfer case went out leaving me stranded luckily only 30 miles from home. Now at 279,000 miles my transfer case goes out again this time leaving me stranded on the wv turnpike. I realize the vechile has high miles on it mostly from towing campers and mostly all highway miles. The total 4 wheel drive miles can't be over 200 miles. I have a friend in indiana who has a 3500 with about 175,000 miles on his and he just replaced transfer case this past week. My question is are we the only two to have transfer case problems? no where can I find any bulletins or anything relating to gm on transfer case problems. Maybe you could let me know if there are any.
2001 Chevrolet Silverado 2500 hd 4 wheel drive. The truck makes a loud banging noise when shifting into 4 wheel drive (on the fly). This happens almost every time when going into 4 wheel drive.
4 wheel drive makes a grinding/growling noise and binds the vehicle to a stop with only a slight turn of the wheel. This did not happen until 17,000 miles on the vehicle and continues to worsen as time goes by. Chev 2001 Silverado 1500 4wd.
Transmission seemed to be in neutral after stopping and applying brake then accelerating. Dealer picked up with wrecker. When wrecker arrived, condition could not be duplicated. Dealer has valve body ordered to replace in transmission. Second problem: rear leaf springs shift causeing a knock when going up uneven grades or speed bumps. Third problem: looseness in transfer case and rear axle cause a clunk when downshifting to stop and sometimes when transmission shifts. Dealer claims normal. Large aluminum driveshaft transfer sound. Just excuse for poor quality product. This clunk or knock also sounds when rear axle moves on uneven grade with axle shifting and driveshaft stationary.
