I backed of the garage and heard a loud noise. As I pulled forward the truck moved very slowly for how far the gas pedal was pushed. I went to go in reverse again but the truck would not go into reverse and could hear a loud whining from the motor. I this just happened to day but I figure it's the transmission. Also, when I bought the truck I had problems with the temp. Sensor and the air conditioning the dealer took care of the problem with the air but the outside temp. Sensor is still broke. I don't know which is worse the failure of the transmission or, seeing all the like complaints on this site with no action.

Transmission failed. Diagnosis was reverse sun shell failure (just like all the other complaints listed on this site)! Gm refuses to offer any cost assistance with the repair or acknowledge that there is an obvious defect that should be recalled!!!
Morning of incident, would here a "clunking" noise after engaging the accelerator. That afternoon, while driving in fast lane of interstate at 65 miles per hour, upon engaging the accelerator, the vehicle was going to have to down shift, and instead, heard a loud "whirring" noise, and vehicle slowed down. Upon evaluation, the vehicle will not go into reverse, and has trouble shifting. Repair shopped diagnosed that the transmission has gone out.
Loud clanking noise coming from the rear to center of the vehicle when shifting from park to forward or reverse, ieee when lack of or direction is changed. 36,000 miles, very poor quality vehicle as I have had several other issues. Good thing I have extended warranty, however I am very displeased with chevrolet and will aviod purchasing any cheverolet products in the future.
Transmission coolant pipes: on the afternoon of november 12, I was driving on a local freeway I began experiencing difficulties maintaining speed. While the engine had full power, I had to pull over as my vehicle effectively lost power to the wheels. At this time, I had the vehicle towed to the local chevrolet dealer where I have the vehicle serviced. The vehicle has always been regularly services at gm dealers. The following monday, my suspicion of a transmission failure was confirmed. Several days later, the old transmission was replaced. At that time, the transmission coolant pipe was discovered to have been rusted through and this was identified as the likely cause of my transmission failing. I ultimately had to have the transmission and that coolant pipe replaced at the cost of several thousand dollars. I believe a strong case exists for calling attention to a need to inspect and perhaps replace critical underbody fluid pipes on similar vehicles due to the likelihood of rust-through and other failures that could cause substantial damage to vehicles.

My transmission went in january of 2005. It is now july and the same thing happened again. I had to fight with the dealership then because I only had the vehicle for 4 months and I am fighting with them again. It is the same problem. It won't shif out of 1st and it won't go in reverse and the loud noise is horrible.
