One problem related to transmission not engage has been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
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!!.
