The Buick Flight Pitch Dynaflow 590050

THE Buick Flight Pitch Dynaflow is unique among automatic transmissions in that it contains no gear shifts. Rather, it employs three turbines, each geared at its own speed ratio to the driven shafts.
The transmission contains a 5-element torque converter — an engine-driven pump member, three turbines, and the stator — combined with two planetary gearsets. The total transmission weighs about 200 lb, a result of the extensive use of aluminum.
The authors outline in detail the design of the unit and its functioning.
