I have a 2000 GMC sierra 1500 with a 4l60e transmission. I just replaced the transmission and now the motor will not turn over. Also the gear display on the dash does not highlight which gear I am in nor do the reverse lights come on when put into reverse. Could the PNP switch on the tranny be the problem or could it be something else?
