Powerglides were passenger car only equipment, other than a few aluminum case second generation transmissions that were used in the early 1960's in short bed sporty fleetside pickups. One of my high school students inherited one of them in very good condition from his grandfather back in the early 1990's. It had a 283 engine, a Powerglide, and the fancy trim package- - - - -one of the very early "Cowboy Cadillac" types!
