  • 12 Volt Overdrive Components

    Where can one find 12 Volt electrical overdrive components? I'm assuming that would consist of the OD relay in the engine compartment, and the OD solenoid and governor attached to the OD unit itself. Anyone know sources for these in 12v configuration? Maybe even non-Stude vendors?

    Not sure if they will fit, but have a T-86 out of a Ford laying
    here in the shop, 57-59 vintage.
    The solenoid looks the same as a stude, but I haven't messed with a OD transmission for twenty years.
    Hope this helps

      Yes, thanks, that does help. I didn't know Ford used that transmission. If they are interchangeable, that opens up a world of parts.

        Late overdrives did not use a relay, but had a different solinoid. What year are you working on ? BTW, Studebaker stuff is not rare or expensive.

          JDP, I'm working on a 55 truck. Previous owner converted some things to 12v already, and disconnected the kickdown switch, opting to wire in a toggle switch on the dash, instead.

          I want to convert all OD components to 12v versions, and bring the kickdown switch back into the system. Basically, make it stock in operation, but with parts necessary for a 12v system. You could say I want a truck that looks like a '55 on the outside, but under the hood looks more like a '56 (the year they went to 12v).

          I honestly don't remember if the 6v OD relay is still there. I do have a copy of the Borg Warner OD operation manual, with its many illustrations and explanations (couldn't do without that).

            If the setup you end up using needs a relay, you can use a regular old Bosch or Hella fused relay, like you'd use for a set of fog lights, rather than track down an original unit. I think they come in 20A and 30A versions, either of which should be sufficient.

              I know I have a 12volt solenoid here. I may have a relay as well. I'll look.

                Thanks for the interchange info, Nate. And Biggsy, hold that 12v solenoid for me, if you have a spare one to sell. I'm in the parts-gathering stage right now. I still haven't had the rebuilt motor shipped here yet (and with its new doubled horsepower due to the hopped up rebuild by G.P.O. Automotive, maybe I'll never need overdrive again ).

                I read on some website just now that the governor should not need to be changed for this 6v to 12v conversion, as it's just a switch. Does that sound right?

                  Since we are on the topic of 12v parts in an original 6v truck:

                  I bought this gas gauge for 1956 and later C-Cabs, to replace the one in my 55, which was not even wired by previous owner:
                  http://cgi.ebay.com/ebaymotors/ws/eB...tem=4604741471

                  Maybe he knew it would not read correctly after he wired the truck for 12v? Anyway, the parts books show a different part number (the one I bought) for 2E-8E C-Cabs compared to the gauge used in the 6v 54 & 55 C-Cabs.

                    I agree that the governor is just a switch; and voltage probably isn't important. Maybe a 6V has heavier contacts. There are 1 & 2 wire governors. The 1 wire provides a ground above 20 something mph. The 2 wire provides continuity above 20 something.
                    Voltage is important, for the solenoid. Also, there are 2 and 3 wire solenoids. The 3 wire brings both ends of the control winding out to terminals. The 2 wire has one end of the winding grounded internally. Both have one terminal that is grounded when in OD. It's wired through the kickdown switch; to ground the ignition points momentarily so od can shift out. It won't shift, under load.
                    If you understand how the different electrical components work, you can do some mixing and matching.

                      Studebaker used a relay in the OD system thru the 1957 model cars and thru the '59 model trucks. After those years, the relay disappeared and basically, it's function was incorporated into the newer style solenoid.
                      The early solenoids (6V & 12V) have only two terminals on them whereas the later type solenoids (later 12V, that is) have three terminals on the solenoid.

                      Yes Dillo, I have a solenoid for you. I'll have to look and see if I can find a 12 volt relay as well. If not, one can easily be made using parts from Radio Shack.

                        Thanks, Biggsy, and everyone else. Seems I recall seeing an article about how to rebuild an overdrive relay somewhere - oh yeah, here it is, although it is for a 6v OD relay:

                            That's good to know, Bill. However, it won't work in Dillo's truck.[:I]
