  • transmission change

    My T86E-1E tranny has had it so i was hopeing that the T86E-1A i have would work in its place? Dose anyone know if i can just put it in and drive? I have a 62'Lark with the 259 V8. Thanks for any info you got. well i guess i can just try it and see. Stanley47

    Same transmission and O/D unit I believe, but different tailshafts. However, I am not technically "up" to know whether you could steal the need parts from one to make the other work or not.

    StudeRich (& other folks) is (are) usually pretty good at this sort of thing...?

      Stanley, check the input shaft to see that it's the same and check the output shaft to see that it matches. If they do, it ought to work fine.

        The Borg-Warner numbers you gave are usually transmission case casting numbers. They don't always indicate enough detail to determine the OEM application. Here's some general info and approximate change dates to look for:

        1. Are you sure it is a Studebaker T86? Are the bolt patterns to the bell housing the same? Stude used two different ones, approx pre and post-'58. Yours should be the long rectangle, not the square one.
        2. Are the input shafts the same length and diameter?
        3. Is the tailshaft length the same? I think most pre-'58 cars and all T86 trucks use the short tailshaft. Yours and most post-'57 cars have a long tailshaft.
        4. Is the output yoke the same? Most pre-'58 cars and all trucks used a bolt-on yoke. Yours and most post-'57 cars used a slip yoke.
        5. Have you checked your potential replacement to determine if it is good-to-go? More than once an orphan transmission is sitting in the corner because it has a problem.
        6. Where are you located? I have a good used '64 T86 from a 259" Daytona.

        Bottom line, if everything looks the same between the two, then the swap will most likely work. I'd double-check to see if the solenoid is 6v. or 12v. Take nothing for granted on Studes. These parts have migrated around from where they were first installed, just as the trans swap you are considering.

        Thnx, jack vines

              The tranny out of a pickup will have straight-cut gears in it, and different ratios for first and second gear. If the entire transmission will bolt in to replace your existing one, you could use it. but your shift points won't be the same, and it will be noisier in lower gears.

              You cannot mix and match any of the gear-set parts between the two.

              If the truck OD tranny is a good one, I'd recommend that you sell it or swap it for a good car tranny. The truck OD trannys are in demand by the truck guys, while Lark-style OD transmissions are fairly easy to come by.

                Thanks for the info. I have a lot of studebaker parts mostly for M5's. I looked today in my bone pile and found another T86e-1A with OD in Good shape. I have a lot of Overdrive stuff. I will see if someone wants to trade or if I can buy one for the lark. Thakns again Stan
