Abstract

A power train for a motor vehicle includes a drive unit, a gearbox having first and second input shafts, and a clutch having first and second multi-disk clutch arrangements assigned to respective input shafts for transferring torque between the drive unit and the gearbox. An operating fluid, especially a cooling oil, is supplied to the clutch arrangements for operation under action of the fluid. An actuator arrangement is assigned to the gearbox for engaging and disengaging gears assigned to the first and second input shafts, and a control unit controls the actuator arrangement so that at least one gear is automatically engaged when the clutch is released.
