While towing trailer with 2 quads (4 wheelers) on expressway with a group of CO-workers, I was attempting to pass another vehicle when my truck would not shift into passing gear. It made a loud "reving" noise and began rapidly decreasing in speed. I pulled off the expressway bringing the vehicle to a complete stop. I then gradually accelerated and shifted manually, but was only able to acheive 1st gear. I had to have the vehicle towed 150 miles to my house where it still sits three months later with only reverse and 1st gear operable at this time.

Problems with shifting on 2004 GMC Sierra. The consumer noticed some shifting problems and noises. The consumer was advised that the transmission must be taken out. The consumer found that the vehicle should have been not sold until repaired. Recall# 04019.

The center hub of the wheels constantly falls off. The plastic screws that hold the hub on the wheel are not securing the hub properly. The consumer has lost six of these hubs since owning the vehicle. The vehicle would buck when put into 4low and shifting into park or neutral from reverse or drive. The vehicle made a thumping noise when making left turns and the consumer could feel it in the steering wheel.

Heard a whining noise and wouldn't shift properly. It would only move very slowly forward and would not go into reverse.

Transmission will slip every so often, also it will make a loud noise when shifting from 2nd to 3rd. This happens alot but not every time. The four wheel drive makes a grinding noise as you start moving and continues for a good distance (4 high).

Transmission shifts with jerk from 1st to 2nd gear with a clunk noise. All other shifting appear to be smooth without the jerk or clunk.

Transmission has "clunking" noise when vehicle shifts from second to third gear when starting and down shifting when stopping. The noise started at approximately 4000 miles and continues to progressively get louder as the vehicle continues to be driven. The transmission has not failed to operate at this time but expect it to fail sometime in the near future.

Consumer complains of premature stalling at idle. The vehicle lacks sufficient power, it surges and at times refuses to accelerate. The transmission doesn't shift down properly out of 4th gear and the air conditioning unit does not cool properly and makes whistling noises.

Engine uses to much oil, knocks, smokes body- truck bed sides are rippeling because the metal is to thin,& can not handel the weight of a lumber rack, front bumper is dented on both sides but in differant places, was like this at delivery, all the trucks were like this but all of them in differant places. Manufacture defect exhaust- loose parts inside of muffler, exhaust rattels from mounting hardware, muffler retains water and leaks at the seams. Paint-rust on the top of cab seatbelt- driver side belt will not recoil,broken seat belt bracket. (this is a safty issue) tires-below 1/32 tread left at 23,000 miles(this is also a safty issue) transmission-makes a cluncking noise at low speeds,takes a long time to shift when running the a/c also makes a howling noise,transmission slips.

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.
