[QUOTE=LILRED66;3623206]All automatics, both Powerglides & Turbo Hydra Matics, and 3-speeds on the column, came from the factory with low hump tranny covers...some removeable, some not. The removeable high hump trucks had granny-low 4-speed transmissions.[/QUOTE

we are using 2 different transmissions or are talking about 2 diffierent transmissions here. I mentioned the hydramatic and you mentioned the turbo-hydramatic. actually upon checking the hydramatic was used in trucks up to 1964 when it was replaced by the aluminum cased turbo-hydramatic, eg; turbo 350-400
the hydramatic was a cast iron cased transmission quite differently designed and built from it's later model, the turbo-hydramatic
though the year of the truck is not mentioned the frt door posts place it within the timeframe that the hydramatic was still being made and utilized.
they quite using the hydramatic ( this model was basic from from 1957) in car after 1960 when another a/case hydramatic or turbo-hydramatic was employed called the slimjim.
the hydramatic was a taller unit than it's follower
