Drive TrainAll Buick Specials were equipped with a new engine for 1956, along with a new dynaflow transmission that added even more power.
The rear pump was an unregulated gear pump driven from the transmission output shaft, which meant it was capable of pressurizing the transmission if the vehicle was in motion. From 1951 on, a cone clutch did the same thing when oil pressure was up, and a spring-loaded parking pawl was allowed to lock the same ring gear in the absence of oil pressure. The tilt case unit had front and rear pumps and could be push started and also could be towed in neutral with the drive shaft in, as the rear pump circulated the tranny fluid. American Cars, 1946-1959 Every Model Every Year. Note that your 1954 transmission was a 1-year Chevrolet truck transmission. Any help would be wonderful!
