  • Transmission Fluid Recommendation?

    What transmission fluid do you guys recommend for my '51 Commander (automatic transmission)? I think I had seen someone post Dexron or Type F?

    Eman, either one will serve you well. Some folks claim the Type F will give you a bit firmer shifts. Frankly, I don't think the difference is dramatic. I used the DexronIII all the time.

    I would recommend that you drain the tranny completely and this means also draining the torque convertor which has a drain plug in one spot near the starter ring gear. If you've got a shop manual, it'll have directions on how to service the tranny. Your car has what we call a DG-200 transmission. It's a really nice tranny with a clutch built into the torque convertor and other features that the later Studebaker automatics didn't have.

    Miscreant at large.

      a full real synthetic, not a "cracked hydrocarbon" imatation synthetic, read the labels well, real synthetics use a PAO base.

        That's a damn fine transmission! Pumps at both ends. You can be running in reverse and throw it in to drive, or running in drive and throw to reverse. It just slows down and starts going the other direction. 225 pounds of air cooled wonder. Shifts in to third at 72 mph.

          Oldcarfart, I'd be awfully leary of what those synthetics would do to those old rubber seal! Dexron III or Type F would be safer, IMHO.[:I]

            Mr. Biggs,
            I agree with your assessment of the Type F. I've been using it in my '59 Lark VI transmission and the shifts are firmer. For me that's reassuring. Haven't even considered synthetics as yet.
