This vehicle is 4 months old and just rolled over to 7000 miles. It is in the shop currently for the sixth time and has now been out of commission for over 30 days. It has had multiple transmission problems; valve body twice, torque converter, shift solenoid, btsi solenoid, floor shifter (with console) all had to be replaced. It is in the shop now for the 4 wheel drive for the second time; 1st time to repair problem I was having and repaired per service bulletin.

My chevrolet trailblazer ext, that I purchased 4 1/2 years ago and it has 44,000 miles on it, has a transmission problem. The chevrolet dealership tells me that it is a 2000 fix. I am angry and disappointed that a vehicle with relatively few miles on it is having such a major problem.
