I have had four (4) transmissions fail in 77,000 miles. They all have failed due to the cooling system becoming clogged, causing the transmission to overheat. The original transmission failed at 35,000 miles. Three others have failed since that time. The first three failed while traveling at normal highway speeds and not towing anything. The most recent failure ocurred while pulling a small travel trailer on flat interstate highway in southern Arizona. Chevrolet continues to put in new transmissions and clear the cooling system. However, the transmissions continue to burn up. Chevrolet has told me the transmission failures are not related and has refused to provide me with a final lasting fix to the problem.

Transmission reverse clutcehes went out at 52,000 miles. Dealer was unwilling to negotiate.. item#2 windshiled wipers would stop working. I would jiggle wiper module and they would start. I took the truck to showcase Chevrolet and told them there was a bulletin was out and they tolfd me my truck was not covered. Iwas charged 90 plus dollars for the part and labor. I think this is a safety issue and should have been covered by the dealer.

Vehicle would overheat and blow oil onto the vehicles behind it. Also, transmission would go out. This has happened 4 times. Dealer can't find a solution.

After we had the truck for 2 years, I started hearing a clunking noise from the rear, when I accelerated, and when I slowed. After a few months, if I was traveling up a grade, the truck would hesitate, then make the clunking noise and lunge forward. I took it to one Chevy dealer, who told me it was up to specs, then to another Chevy dealer, who informed me of tsb #564401A, which is my exact problem, and provided me w/ a copy of the tsb. Although it says that the performance of the truck is not hindered, it's wrong. The clunk is becoming more frequent and louder. The truck won't go up hills without hesitating and lunging forward. The tsb says that dealers are discouraged from trying to fix the "driveline clunk" which is ridiculous. I've written GM two times, and copied the dealer from which I bought the truck, and no one has contacted me. I'm concerned, because the website "alldata" indicates that tsb #564401A (driveline clunk) was the subject of a recall. Is this true" the tsb says that the clunking sound is the result of "built-up freeplay". what's that mean? what does built-up freeplay result in after years of operation" the truck goes down the road making a clunking sound, through no fault of my own, yet GM refuses to even attempt to fix it.
