2009 hummer h3 wont go forward but go in reverse. What will be the problem? Thank u
Good question, could be anything from a faulty gear selector switch to a total transmission rebuild. Just too many things that can happen, and without the right diagnostic equipment you just won't know. I suggest that you have it towed to a good tranny shop, they can plug in and run stand alone test to determine if it's electronic or the tranny has indeed went bye bye.
