  • Transmission / Overdrive: Lock out overdrive wires

    Same problem with the overdrive lockout switch I can’t tell which wire goes on which. Any advice? Thank you in advance

    Doesn't matter. It's just a pass through switch. Goes open circuit when the plunger is depressed. It was eliminated in the 1955 model year.

        Where is that switch on which Studebakers? I've never heard of a 'lockout switch'. I thought the cable locked it out. Thanks.
        I really would like to know more about that switch.

          I recently noticed my lockout dangling down in my 54 sedan. The switch body broke off. Ordered one from SI, installed and test drove the car. The car wouldn’t kick down into OD- tried to test the solenoid using the wire at the relay- it was dead and wouldn’t actuate. Yesterday, I pulled it, wiped off 69 years of accumulated stuff, then tested directly on the battery- it worked. I then reinstalled it and went in a test drive. All is well now, and it worked like a champ- er- Commander! I’m a happy camper now!!

            Howard the Switch is not called the "Lockout Switch", it is the "REVERSE Lockout Switch".

            Not too many people drive 32 MPH in reverse, so it was eliminated !

            It only locked out the Overdrive when shifted into Reverse. It was wired in line in the Solenoid Circuit to open it and prevent a Overdrive engagement.

            Used on Postwar Cars '47-'54.
