While driving on the hwy. Towing my 28 ft 5th wheel trailer on level ground we experienced a loud bang and the feeling like something in the driveline had broken. No engine malfunction indicators were displayed on the console. No further incidents have happened yet, but it is constantly on my mind.

I own a 2001 gmc sierra. I noticed that when I put my truck in 4 low on my 4x4 (manual shift),and I put the truck in reverse, you can feel the torque. When I go and put the truck into park it starts to grind while engaging in the park position. I brought it to a gmc dealership and they told me that it is normal for the transfer case to do this. If you ask me, if there is grinding noises on moving parts, something is not right or "normal".

The consumer heard a clunking noise and a pulsating sensation in the steering column while making turns. *nm the consumer was told that the wrong lubricant was used at the factory for the steering column shaft. The shaft was unable to be lubricated because the lubricant would not penetrate between the first and second sleeve. The intermediate steering shaft was replaced and the problem got worse. Four wheel drive warning light came on.

We have a 2001 gmc crew cab that we have had for 26 months. Be bought it brand new so we would be less likely to have problems. We have had 3 new transmissions (not including the factory one). It is in the repair shop again because when you put the truck in reverse it dies. Not every time but it happens quite often. It was in the shop before for the same exact problem which resulted in 1 of the 3 new transmissions. Lets hope it doesn't need another one. This is getting old!!!!!!!!!!!

The transmission violently shifts into gear upon acceleration from a stop or slow speed. This problem has occurred as many as ten times since the original date of purchase. On may 4th it occured so violently that the passenger in the rear hit his head on the rear window. In this incident the shift was so hard the rear wheels left the ground(all 4) and then the truck lurched forward. This is a serious defect that could caused harm to those inside the truck and could harm other drivers or pedestrians. The truck seems to go to a neutral operation even though you are in drive then when the RPM"s icrease to above 2,000 it suddenly shifts. I have taken the truck to the dealer 5 times and recently completed arbitration to take the truck back. The gmc represenitive claimed that this was normal for a "heavy duty" transmission such as the allison. The best discription of the problem is it feels as if you have been hit from the rear by another vehicle at 15-20 MPH.
