2004 Chevrolet Silverado. At about 20,000 miles the truck started to hesitate whenever I would take off from a red light, it would do this about once a month or so. At 30,000 miles or so, it would kind of jump into gear when first taking off or jump into reverse. Dealer would say they test drive at each oil change but could not find nothing, I was sure they wouldn't because it didn't happen every time. Now it's occurring every other week or so. Finally at 76,000 miles it wouldn't get pass second gear, dealer finally found a problem and now it's $2800 to replace parts. No heavy city driving, I only live 5 minutes from work. I put the truck on the highway once a month to travel about 300 miles round trip. The only time the dealer wrote anything down, I discovered, was after the warranty expired. I talked with another 2007 Silverado owner and they have 17,000 miles and the transmission is jumping into gear.
Failure of the neutral position safety switch, 2004 chev Silverado diesel with allison transmission. The safety switch shorts out and fails due to wet driving conditions. This failure results in the transmission going into a "fail safe" condition that does not allow the transmission to shift, stranding the vehicle. Chevrolet has redesigned the part now 3 times, but will not warranty or stand behind their product. This switch has failed on me twice during snow conditions.
When vehicle has been driven for less than 2-3 miles and when transmission is cold the following occurs: when the vehicle operator stops at an intersection, stop sign, or street corner - the engine and transmission continues to propel the vehicle forward while the brakes are applied. The result is that the brakes are fighting against the engine. The vehicle operator must put the vehicle in neutral to stop the vehicle. In many cases, the vehicle travels well into the intersection or well past the normal stopping point before it finally comes to a halt. The result has been several near colliisions with cross traffic. The dealer has been consulted, but the response has been: "unable to duplicate the problem - all systems operating correctly" "this is not true!! this vehicle has only 16,000 miles and is 18 mos old - but this has occurred nearly 10 times. The most recent is 12/2/05.
