A new five-speed automatic transaxle, U150E, has been developed for FWD passenger cars. The goals of the development of this transaxle are fuel economy improvement, better acceleration performance, and a smoother shift feel. U150E achieved its targets by adopting a wide gearing range and using hydraulic control system design based on various simulations. This paper describes the major features, performance of this automatic transaxle, and technical points of the development.
