We had an issue with our Trailblazer this past Sunday. While driving to the store it locked up all of a sudden nearly sending us thru the windshield. Was able to drive it into a parking lot and it was bucking and the cel came on. It wouldn’t go into reverse and noticed that the R was blinking. Had it towed to the dealership and on Tuesday afternoon the service department told me that the transmission needed to be replaced. The trailblazer only has 17,800 miles on it. Long story short, we had enough and traded it on a new 2025 Chevrolet Equinox LT AWD and took our new Equinox home the same night.
