problem #2

Sep 172008

Trailblazer LT 4.2L V6

  • Automatic transmission
  • 85,621 miles


Had to have the tranny replaced. Their is no reason that GM should have this many transmission failures at such low mileage.Especially in one model. It's just poor design from the engineers. I think these college educated engineers and top brass try to do this so people will have to spend money to fix them. All it does is upset people with GM and they will go buy another brand or foreign brand of some kind. Come on GM get with the program. You can do better then this.
