The Stovebolt Site Forums The Shop Area Engine Shop Will 57 passenger car tranny work in a 59 truck?

I have a good three speed from a 57 Belair...Will it work in my 59 long bed?

Yes. The only issues will be that you'll have to use bolts and nuts on the lower mounting holes, as the truck bellhousing isn't tapped like the passenger car and the passenger trans isn't tapped like the truck, and you may need to swap the shift arms, but otherwise, it's a bolt in.

Thanks Bill! That's great news...Now I can spend that money on something else like hubcaps. Hey, I just thought, Will the passenger car drive shaft work too?

I'm not sure on that, there may be a length issue, however, the original truck driveshaft will work fine with the car trans.
BTW, I have an overdrive version of that trans from a '55 wagon, with a few parts from a Power Pack equipped '57 convertible, in my '55 3200. Works like dream.

I used grade 8 bolts and nuts on the bottom mounting holes. Both the transmission and the bell housing holes were large enough without drilling and there was room for the nut. This is on a saginaw out of a 72 Nova and a factory V8 truck.
