Outline

Contribution to low fuel economy

•  Wide TCC range

•  Clutch/brake resistance reduction

Realized direct feel and quick shifting

•  Oil passage resistance reduction and improved clutch/brake response by optimizing clutch rigidity

•  Improved solenoid valve response

Smooth and powerful start-up

•  Torque converter characteristics when accelerating and optimized range

Smooth shifting

•  Control valve body integrated with TCM adopted

•  Direct linear solenoid valve has been adopted to improve shift accuracy
