I just went thru the same thing. The problem was mainly corroded
connections. The OD solenoid draws about .85 amp at 12 volts, so a few
ohms resistance can cause the solenoid to disengage. My car is a '69,
so the OD switch is on the steering column, I guess yours is on the
knob. ? Anyhoo, there are several connections in the car's and the
gearbox's wiring harness. Start by cleaning each and every one of them
and make sure they're tight. report back. (G) BTW, I run 20-50 in my
gearbox, no probs.
