Nice attention grabber title I know... I am serving as a ********** in ************ but fortunately get to come home for christmas to spend time with the wife and kids... About six months ago, my wife was driving our '04 Suburban LS 2WD on the highway at about 60 MPH... she threw it into reverse by "accident" and the tranny grinded the Burb to a halt on the shoulder and the motor cut out. 5 minutes later she was able to start the thing up and continue driving. Since then she has towed our trailer with it, driven all up and down the west coast, and the only problems she describes are the fact the tranny down-shifts or changes gears too much, even at a constant speed... and the speedo bounces all over the place as a result of what happened six months ago. My questions are as follows: Is there an easy fix to the tranny issue? Probably not... What about the speedo? Is there a speed sensor on the tranny casing that could have been damaged? Can I maybe just swap out the cluster for another one? Any help would be greatly appreciated. Cheers!!
