When did the transmission go out on my Trailblazer?
Reopened for updates. The transmission went out on my 02 Trailblazer last night for the second time. The initial failure occurred 1 year ago almost to the day, the vehicle was 18 months old and had 32,000 miles. In drive it suddenly started slipping and making a loud whine. It would not shift, but sometimes would “catch” enough to move forward.
Why is my Chevy Trailblazer not getting any power?
This problem is very intermittent, and occurs usually on a cold start. When I start the car it revs extremely loud and fast, and even if I allow the car to warm up for over one minute, the revving goes on higher than normal. Then, when I put the vehicle in drive, it bogs down in a higher gear than first, and I can’t get any power.
What are the signs of a transmission problem?
