Consumer has multiple problems with vehicle. Bearings in the drivetrain are defective/ alignment/brakes repaired/rear end replaced, and other problems developed due to the bearing. An authorized gmc repairman told consumer that's the way gmc makes vehicles. Consuemr insisted that has had nothing but bad expriences with the vehicle, and manufacturer.
Transmission hard shifts from 1-2nd after driving for several miles. I can turn off the ignition and this will solve the problem for about 10 miles. Then it will start shifting hard again. Engine light is on. Dealer couldn't diagnose the problem.
Bumps into gear, engine check light, transmission overflow drips, power steering pump needs replacing

Vehicle stalled while driving. Had coasted to side of road. Restarted & vehicle shut off. The differential seal was leaking oil. The vehicle was making noises in the universal joint. Taking vehicle to mechanic. Also, leaf spring on passenger's sid efailed/replaced/smelled oil due to pcv valve failure, an dtransmission would not shift into drive or reverse.
When gears are shifted from first to second vehicle jerks, as if being rear ended. Dealer says there is a bad valve body in transmission. Dealer has seen vehicle 3 times. No solution found.
I purchased this truck in january 1998. 2 weeks later it was in the shop. This pattern continued each time. The complaint was concerning transmission. But each time they would replace something else instead. The truck was in the shop for over 50 days in a years time. On october 4, 1999 I was on my way to work when the truck going down the highway, jammed in 1st gear. The truck was towed. It took the dealer 10 days to make a decision on repairing the truck. They were well aware of this problem, and it is still a major hassle to get it repaired. Contacted gm and had to have them intervene. Had they of fixed the truck the prior 5 times it was in for repair this wouldn't have happened. They continually denied problems existed with the transmission. This is a vortex truck I don't know if there are other existing problems with this year of truck and transmission problems. But I had problems within the first week after purchase and each and every time they would repair something else instead of fixing the transmission. The tranny was in pieces when it arrived to the dealer from the tow truck. They still did not want to take responsibility. They were trying to force me to pay a part of this repair. They were very ruid and incooperative about the whole deal. A total of 16 days they had the truck this time. In october of 98 they had the truck for 19 days and still could not find out what the problem was. Each time I would get the truck back they would show some repair for anything other than my complaints concerning the transmission. Each report reflected complaints about the truck no shifting into gear from 1st to 2nd. They gave me a blow off memo from gm. Stating the whnining noise from this transmission was normal. However, they failed to realize their memo relfected problems from park to gear and from n to reverse. My truck would fail to shift from 1st to 2nd and it would whine. And it would clunk and still they didn't fix it.
Trans started shifting very hard. Once in high gear operated well. Dealer would not look at it under warranty even though 1yr 10 mos. Old due to over 36000 miles by less than 2000.
Automatic transmission/ overdrive malfunctioned, causing an abrupt forward jump from 1st to 2nd gear which may cause a crash. Please provide further information.
Rear differential is leaking.
Transmission does not shift correctly, causing loud noise and possibly resulting in total failure. Dealer cannot fix defect.
While driving the vehicle experienced sudden acceleration at a high speed without prior warning which almost resulted in an accident. Was able to stop the vehicle with the brakes. Also, dealer replaced the transmission.
Transmission failed.
Vehicle makes a thumping noise due to defective rear differential locking unit.
