    decide what tranny you want. with a 6 cyl im presuming you want a powerglide or a turbo 350.

    youll need to remove your stick tranny. remove the pilot bearing in the crankshaft.

    find a transmission/torque converter/automatic flywheel
    bolt it up,
    buy/make a rear transmission mount
    have your driveshaft lengthened/shortened to compensate for the different tranny
    youll need a front driveshaft yoke for your selected transmission
    you will need a shifter and it would be easiest to take a new one out of the box and bolt it up, floor mounted.

    does that early 55 have an enclosed driveshaft? If so, you will need to put a different rear axle in.

    thats a general gist.

    If you go with a modern trans, an adapter to the 235 is needed. And that gives you a place to bolt the starter to.

    is it an swb or an lwb? It might be tough to find, but it would be easiest to find a whole pu with an OG powerglide setup--then you would have everything.

    btw, this is very basic knowledge but if the OP doesnt know, a powerglide has 2 forward gears and a th350 has 3.

    they BOTH only have one reverse though :)
