I had a '52, a couple of 53's and a '57 olds with Hydramatics and they were a good solid
hard shifting transmission. Beefing up the valve body with stiffer springs and or shims
allowed higher rpm between shifts and even when stock you could manually shift them
almost like a stick.
I would think that they were the same trans used in the mid-50's trucks.
