I have a 97 dodge 1500b ram van. It will not go into overdrive. I have replaced both solenoids and still will not go into od. I have checked all fuses. Please if anyone has any suggestions it would be much appreciated. Thanks
You tap into the connector at the tranny with a pair or wires and run them up to the cabin. There you connect them to a meter and then go for a drive. When the OD is supposed to kick in (35 MPH) the meter should jump up to 12 volts. If it does the problem is in the tranny, if it does not the problem is in the wiring, a connector, the PCM, or with the speed sensor.
So I have replaced the trans with a rebuilt trans that my father in law had in his old van. The trans was working perfectly in his van. I have it in my van now and it still will not shift into od and is locking it out. I checked the speed sensor while driving and the PCM only sends out 7 DCV. Is it possible to swap PCM's or does it have to be programmed by a dealer?
