I have a 2000 Chevy Silverado, 5.3L, 4L60 Tranny.
Original Transmission would not shift out of 1st or 2nd gear in higher gears. Bought and installed a rebuilt transmission and have the same problem.
What gives?
Local Chevy garage tells me it needs to be programmed! If that is the case why did the original tranny do the same thing. Can someone give me directions on where to start to fix this problem. All help appreciated...
