My '64 Spitfire has a single rail transmission and associated overdrive. It has been misbehaving lately. It stopped working once and I replaced the fuse. Problem solved, I thought.
Recently, it stopped working and the fuse appears to be good. Driving home from an event, I turned it on expecting that it might have somehow fixed itself, at least for a while - this has happened previously - no such luck. Later I noticed while shifting into third gear, the car sounded as if the overdrive was engaged, (drove like it, too.) but as far as I could tell there should have been no current to the solenoid - the switch was off. So I drove home in top gear, seeming to be just a bit faster than idle.
Can the overdrive engage without power? I wonder too if transmission oil level could have an effect. Though as I recall, when oil gets too low it stops working.
I need to solve this so I can put this car of the road, so I can repair my wife's Spitfire shift lever.
