  • transmission interchange

    I have a chance to buy a good (fliteomatic?) that is coupled to a 60's 289. The guy is willing to sell me the transmission as he wants to use the engine in one of his projects. I don't know the exact year of the engine and transmission, but I believe the engine is full flow, sorry I have no idea when they started doing that. I think it is safe to say it was made some time between 60 and 64. What I would like to know is this: Will it drop right in to my 58 Commander with a 259 and a blown fliteomatic? thanks in advance for any help.

    short answer, yes, all 58-up V-8 FOMs will interchange with any other 58-up V-8 FOM. if it is original to a FF engine it is mid-62 up. Make sure that it is indeed a FOM not a powershift (run the shifter through the detents, FOM is PNDLR and PS is PRND21, there's an extra position) and if it is a HD unit you'll need to get a cooler, other than that not much to it.

    The only "gotcha" I can think of is the dipstick/fill tube; I can't recall when Stude ditched the in-the-car filler. You won't be able to retain that with the late FOM as the underhood fill/dipstick tube connects to the pan (there's no provision for the short fill/dipstick tube in the later cases.) If you currently have the early style in-the-car fill/dipstick, you'll have to verify that the later long tube won't hit anything; I know that it won't work in an early C-K with stock exhaust, so you may need a new (Lark? or custom?) main exhaust pipe on the passenger side.

    the good news is that Stude didn't seem to change stuff for the sake of changing stuff, so stuff bolts up that you wouldn't think would work. My '55 coupe is running an R1/4-speed but for a while I was running a 289/late FOM, my exhaust is all stock '55 with the exception of the pass. side head pipe and main exhaust pipe which are GT Hawk, this appears to clear any possible combination of engine/trans I could throw in the car and will bolt up to anything I'd want to put under the hood except for R3 style headers (for which I'd have to get new head pipes.)

    good luck

      Thankyou so much for your help, I will post a second question and see if anyone know when Studebaker discontinued the in car trans filler, The transmission is quite a ways away from me and I have not had a chance to see it yet.

        Unfortunately my shop manuals are silent on the issue - although my original '58 supplement indicates that it still had the underfloor filler. (my late shop manual is a reprint, and apparently is missing a page in the FOM section)

        going by the parts book, it appears that the underhood filler was introduced in '63? oddly enough a) it appears that different chassis used different pans and b) the same pan was used with and without the underhood fill tube (I guess the drain plug threaded into the same hole the fill tube used?)

        You may be worried about nothing; hopefully someone can chime in and say whether or not it will clear the exhaust pipe on a sedan/Lark type. my comment was based on my experience with a C-body.
