Overview
The Tremec ACT 7 speed Dual Clutch transmission is a automatic shifting manual transmission with full manual paddle shifting option. This is a fuel efficient transmission that is capable of handling high torque applications. The internal clutch is a high efficient dual wet clutch. The planetary gyrator pump provides the system pressure and lubrication. actuation system with low leak solenoids provides the fast and precise clutch and gear control.
