ABSTRACT:
A method for launching an automatic vehicle transmission utilizing dual clutches in place of a torque converter avoids clutch overheating, sudden launch or roll-back by placing a clutch in a slip mode only after the vehicle's brakes have been actuated and fully disengaging the clutch upon over-heating detection. When launch is initiated, a first gear engaged and the brakes are released, the associated clutch is fully engaged to avoid overheating.
