Noises During Shifting problems of the 2005 Chevrolet Silverado 2500

1. I bought a used "certified" 2500 hd silverado with 33000 miles on it. I have owned it abut three months. On three separate occasions I have noticed the transmission slip or "hesitate" when accelerating from a stop. The engine will rev but the car does not move. When I let off the gas I can feel it shift suddenly and the car will move. 2. I noticed a whining sound in the transmission when it is in gear. Chevrolet service department tells me it is common on my truck and there is nothing they can do about it, it is the plenary. The sound is louder and continues throughout the entire driving range. It began at about 35000 miles. The service rep stated they had a service announcement on it, but I have not seen that yet. 3. About three weeks after I bought the truck, I noticed a clicking and grinding sound when the brakes were applied lightly. First time in the dealer could not find anything. Second time in they found the left rear axle seal leaking and replaced that. The third time in they adjusted the brakes so that it was almost impossible to apply light break pressure. After a couple of days of use the brakes loosened up some and now the clicking and grinding noise is back and it is more noticeable with even a little heavier pressure on the brakes. I will be scheduling a return trip for this and the whining sound in the transmission, but gm seems to take the approach that if it is "functioning" don't repair it.

The contact owns a 2005 Chevrolet Silverado 2500. While driving 80 mph, the vehicle automatically downshifted to second gear. The contact was unable to shift gears. He took the vehicle to the dealer and they stated that there was nothing wrong. The vehicle downshifted again while driving and the dealer repeated that nothing was wrong with the vehicle. Another dealer stated that the transmission was burned. In April of 2007, they replaced the transmission at 26,102 miles. After the replacement, the failure recurred accompanied by a severe grinding and slamming noise. The vehicle then shifted into third gear. Since the transmission was replaced, the vehicle has been to the dealer at least ten times. As a result of the transmission failure, the contact accidentally struck a deer. A police report was filed. General motors developed a case file on November 13, 2007. They called the contact the following day and stated that the initial representative working on the case was unavailable. The contact has yet to hear back from general motors. The failure mileage was 20,000 and current mileage was 34,700.
