In 1956, the General Motors Hydra-Matic (which still used a fluid coupling) was redesigned based around using two fluid couplings, to allow a "dual range" feature. This transmission was called the "Controlled Coupling Hydra-Matic", or "Jetway" transmission. The original Hydra-Matic remained in production until the mid-1960s. In 1964, General Motors released a new transmission, the Turbo Hydramatic, a three-speed transmission which used a torque convertor. The Turbo Hydramatic was among the first to have the basic gear selections (Park, Reverse, Neutral, Drive, Low) which became the standard gear selection used for several decades.
