AISIN AW New Six-Speed Automatic Transmission for FWD Vehicles

AISIN AW has developed a six-speed automatic transmission TF-60SN for front wheel drive (FWD) vehicles. This new TF-60SN has been developed based on the concepts of minimizing length and mass increase as compared with current five-speed automatic transmissions, and providing the world's first transverse FWD six-speed automatic transmission. This has been accomplished using a newly developed planetary gear set, and a new “squeezed” torque converter. In addition, the control system features a unique design that maintains outstanding compactness and achieves a high quality smooth shift feeling. This paper describes the construction, characteristics, and functions of this six-speed automatic transmission.
