I started the trailblazer and shifted it into reverse to back out of the parking stall and I heard a loud pop sound and when I tried to give the vehicle gas it didn't do anything but rev the motor. It won't move in reverse gear. The vehicle in front of me moved and I was able to shift into drive gear and it would move but it wouldn't shift from first gear.

Driving my son home from football practice and heard a weird sound and noticed the gears would not shift in the transmission. I tried to put the vehicle into reverse and it would not work. I had no warnings about this and just about got hit due to having to try to pull off the road quickly. This is the first time it has happened and we are going to try to buy a new transmission.

I bought the 2002 trailblazer on february 2008 drove it for about a month and a half total the rest of the time it has been back to the dealership for repairs. Everything including the motor needed to be replaced, the transmission needs to be replaced just accelerated onto the gas heard a loud crack and the truck shook like an earthquake had hit, lost acceleration would not go any faster than 30-35 miles an hour and car would not disengage from neutral at first and the would not go into reverse., brakes have made a pulsation feeling and they were done days before I bought the vehicle and replaced again including rotors a month after I bought the vehicle, there have been too many crackling and metallic tinging noises that don't go away, the 4 wheel drive engages and disengages on it's own when driving 65-70 miles an hour. The steering wheel had a constant rubbing noise and dealer told me all of my complaints were nothing detrimental and basically blew me off. The truck jerks alot on it's own doesn't matter if I am in motion or if I put it into gear or park it jerks. I don't feel safe in this vehicle, it seems to be possessed. I am scared to death to drive it, so I have stopped driving it. I don't know what to do. My first car was a chevy and now this one, I will never own another chevy product. I don't know what to do, I don't want this. I fear my own and everyone else's life!!

I purchased a 2002 chevy trailblazer the transmission went out at 15053 miles with previous owner 2-3 shift solenoid in transmission replaced. The transmission went out with me at 33431 miles, still under factory warranty. Dealership found shell stripped out reaction carrier teeth broke replaced all clutches replaced 2/4 band. At 83029 miles transmission went out with me again. Vehicle is now out of warranty. Dealership found reaction sun gear stripped inside reaction sun shell. Replaced sun gear and shell & o/h transmission. I called gm customer service and asked them to replace the entire transmission because I felt something was causing these parts to keep going bad and this is the 3rd time. I felt there could be one part that came from the factory in this transmission as a defect. Gm agreed to pay parts if I paid labor to replace parts not replace complete transmission. This cost me $840.00. Now it is 119000 miles and transmission gone again. I called gm to explain to them that this is the 4th time and I requested a new transmission and a refund of my $840.00 from last time because for some reason this transmission has a pattern of going out at approximately every 30 to 40000 miles. Gm would not assist me with any assistance. The diagnostic this time shows would not shift out of 1st but to determine what parts were bad it would have to be broken down. I was hoping gm would assist me in this matter but I seem to get no where. I hope you can help!

Pulling onto the highway, when transmission popped and began to whine. Reverse gear lost and stuck in 1st gear. Took to dealer where diagnosis was failed (stripped) reaction sun shell. Fortunately vehicle was traveling at low speed. Concerned that failure could have occurred on the highway at greater speed. This vehicle was never used for towing or subjected to any abuse whatsoever. This is a common failure in the 2002 models built during a certain time period. Dealer gave some cost concession on transmission replacement, but unwilling to admit component weakness. Called gm customer assistance line with no additional support.

Went to get gas for my 2002 chevy trailblazer and we I finished and I started my car I put it in reverse and heard a loud clunk noise and then the truck would not go into reverse. Then I put it in drive and heard a lot of grinding. I called gmc and they know the trailblazer has a defective transmission and now that I call them with my problem they tell me that I just need to get a gm diagnostics test. Done and it just another way for them to get money out of people.
