    The tranny would not shift when in the car, with no electrics hooked up. When we originally hooked up the battery cables the car started up, as per a previous topic. I have dropped the tranny out of the car and decided to put the 3 speed back in. I just need everyone's input before I have the tranny serviced. If it's something I can do at home all the better. At $90/hour things get expensive in a hurry.
    I'm not a mechanic, but a good friend helps me out. He too is totally in the dark with this overdrive. So any help that people can come up with would be appreciated. Thank you.

    I had the same problem when I had my 64 Champ truck. The contacts in the governor would stick periodically causing the same no reverse problem. One time the trans got stuck in overdrive and I had to remove the solenoid from the transmission to get the overdrive to disengage. I finally replaced the contacts in the governor to solve the problem. Bud

    The overdrives are built so that they will not go into reverse while engaged in overdrive. If yours is not going into reverse, your transmission is not disengaging from overdrive as you slow to a stop. If this is happening, you should also notice less power when releasing the clutch to start off in first gear. I have had this problem with my '48 coupe from time to time. Mine is inconsistent when I have the problem. While stopped, you should be able to pull the manual cable out to disengage the overdrive and then it should shift into reverse. When you are operating the car in automatic overdrive (with your cable control pushed in) the governor grounds the circuit at about 25mph and enables the transmission to shift into overdrive. When you slow to about 15mph, the governor opens the circuit and the solenoid should disengage the overdrive. I think that in your case (and sometimes on my car) the governor is not opening the circuit and this causes the car to remain in overdrive when it should not. (If this don't properly 'splain it...somebody else chime in and let's bicker about it!)

    So is the problem that the shift lever on the column will not move into the reverse position?

    Is this true with the OD handle both "in" and "out"?

    I couldn't get the gear to go into reverse by hand using the leaver attached to the tranny case.

    I had the same thing happen before. I seem to remember that the governor wasn't 'releasing', causing the OD solenoid to stay engaged. Check to make sure that nothing is grounding out anywhere.

    But will the transmission go into reverse (with the shift rod removed)?
