Hi, I've got a 1992 Ram 150 5.2L 2wd with about 210k. I haven't had overdrive for quite some time now, and I'm finally getting around to trying to fix it -- truck shifts well other than that. I'm hoping its just a wiring problem, computer has the overdrive solenoid code and the o/d on/off button on the dash will not light. I want to hook the solenoid directly to power to test it but I don't know where the wiring for it is. The Haynes manual doesn't mention it at all. I thought that it was the orange/blue wire on the tail housing, but that turned out to be the speed sensor. The only other plug I can find is a three prong that I believe is just neutral safety and reverse lights. Does anyone know where the wiring for the o/d solenoid inputs into the transmission?
Thanks
