The OD in my 1953 Ford Courier is not working. It’s identified as the Ford 3-speed with R10 OD, but I have no history on this car and can’t confirm that it is the original/correct unit. I believe the culprit to be the solenoid. I say that as all other mechanical and electrical components perform or test properly on the bench or installed:
- 3 speed works great – recently rebuilt; upshifts, downshifts, no noises, oil was free of debris…just as you’d want
- OD cable properly adjusted – easy to operate; when coasting there is engine braking with cable out (“locked out”) and no engine braking with cable in (“in-gaged”)
- Governor bench tests properly and grounding surfaces clean
- Relay can be heard to click with ignition on and governor wire grounded; voltage checks at solenoid feed wire
- Kickdown switch properly goes from NO/NC to vice versa at WOT.
The solenoid bench tests fine – great sound and action when hooked straight to battery. But no sound or action is detected when the solenoid is installed and “bench” tested (now in car) with same battery, wires, and connection points. Solenoid assembles to the trans as it should: insert, twist ~90 deg to align bolt holes, check to insure you cannot pull it back out. This under-car bench test has been tried with cable in and out – no difference.
Should I be hearing/feeling the plunger action when activated in the car? I note comments that say there is a unique solenoid for wagons. Couriers also? How to identify? What’s different? Mis-built OD in trans? Other? Thanks to all of you, especially Mac. I have read numerous posts and they are very helpful.
