Jim Yergin Posted August 9, 2008 Report Posted August 9, 2008 I have a '53 O/D transmission in my '41 Plymouth. In my second attempt at a test drive a couple of weeks ago, after about 100 yards the car refused to move in any gear. Once I pushed it back into the garage, I discovered that the gear selector rod was broken. I replaced the rod. I have the car up on jack stands and today I started it up to see what would happen with the car in gear. Again, the drive shaft was not turning. I then tried it with the manual lock-out pulled out. Now the drive shaft was turning and was driving the rear wheels. Finally I pushed the manual lock-out back in and now the transmission is driving the rear wheels. Does anyone have any idea as to what is going on with my car? Thanks. Jim Yergin Quote
James_Douglas Posted August 9, 2008 Report Posted August 9, 2008 Jim, Sounds like something got hung up, possibly in the cage-roller-cam section of the OD. Have you ever since putting it back in had it in OD for any length of time? James Quote
Jim Yergin Posted August 10, 2008 Author Report Posted August 10, 2008 James, I have never driven the car in O/D. I have yet to install a fuse in the relay and in my two very short and aborted drives I never got out of first gear. My plan right now is to leave the car up on the jack stands and "drive" it while stationary in the garage and see what happens. Jim Yergin Quote
James_Douglas Posted August 11, 2008 Report Posted August 11, 2008 Jim, Because of the way the OD works, using friction at the balking ring and torque reversal, I am not sure if the car will shift into OD on jack stands. It may or it may not, I am not sure... James Quote
James_Douglas Posted August 11, 2008 Report Posted August 11, 2008 To test the thing, just run a wire from the SOL to a toggle switch and on to the battery. Use #8 wire. Drive down the street and have someone hit the toggle switch. just DO NOT allow the thing to go backwards at any time with the switch on. That by passes all controls and tells you if the unit is working. They you can start putting in the control systems. James Quote
Jim Yergin Posted August 11, 2008 Author Report Posted August 11, 2008 Thanks James. I will just be testing the car in regular drive to make sure it stays in gear. If so then I will road test it and work on the O/D set-up as you suggest. Jim Yergin Quote
