High Energy Slipping Friction Material for Torque Converter Clutch

In recent years, several new types of automatic transmissions were developed and launched. Especially, the multi-step automatic transmission as a 6 speed can provide good shift quality and better fuel economy. Improved technology for torque converter clutches is important in order to achieve further improvement of fuel economy and efficiency. This paper describes the development of new friction material optimized for high energy and high speed slipping condition of slipping control torque converter clutch.
