Hi guys. I have some problems with my 4l80e. it has to run for a while and I have to go through all the gears before I can drive or it won't shift right. I have to do this after it has only been standing for a few minutes. After I do this, it shifts perfectly. It has new oil and filter.is this normal? Kind of annoying to have to do this every time. Thanks :) Its a 1991 Suburban 6,2D

Could be a solenoid problem. It's a computer controlled transmission and diagnostics would have to be run to determine the cause.
