my mitsubishi 3000gt 57,000 mile auto tran just lost all foward gears rev is OK

I am not mechanical but I am curious ... what do you mean by "the correct bulb?"

I only ever seen this one time but it was on a Mitsubishi it had a brake light bulb in the reverse bulb socket it thru off the computer thinking the car was in rerverse always.Probabley not the case with you but dont overlook it.

sounds strang ... I'll check Thanks
