I have the same problem and it's driving me nuts because I do not want to drive the Truck and damage the transmission. Does all the lights still work on your dash.

I'd have someone put a code reader that can read your TCM on it.

My 1994 Silverado 5.7 would not shift into overdrive. New spark plug wires solved the problem.

Knowing what your working on would be helpful to determine what transmission you have,
