ABSTRACT:
A torque converter including a damper assembly connected to a hub for the torque converter; a turbine clutch connected to a turbine and the damper assembly; and a torque converter clutch connected to a cover for the torque converter and the damper assembly. In an idle mode, the turbine clutch and the torque converter clutch are disengaged and the torque converter cover is rotationally disconnected from the hub. In a torque converter mode, the turbine clutch is engaged, the torque converter clutch is disengaged, and the turbine clutch rotationally locks the turbine and the damper assembly. In a lock-up mode, the torque converter clutch is engaged and the torque converter clutch rotationally connects the torque converter cover and the damper assembly.
