A New Five-Speed Nissan Automatic Transmission for Passenger Cars

An electronically controlled five-speed automatic transmission has been developed for use in new 2-liter models. This high-performance gearbox is the world's first five-speed automatic transmission for passenger car use to be equipped with a torque converter. It is designed with an ultra-wide range and close ratio gearing and incorporates a host of outstanding technologies to provide excellent performance and driveability.

This paper describes the major features and performance of this new automatic transmission and some of the studies undertaken concerning multiplication of gear steps.
