I am in the process of "restoring" a 53 6400 Chevy, and needed some parts. So I found and purchased a '47 with the parts i needed with a bonus 5 speed tranny. It has a shift pattern plaque on the dash that has the words "TruckStall" on it. Does anyone know what tranny this could be. I'm thinking of swapping it in just for the cool factor of a 5 spd.
