Abstract
A shiftable gear transmission has a plurality of gear pairs with free gears that can be engaged to one of the shafts by means of shift clutches and fixed gears that are permanently locked to one of the shafts. A start-up clutch arranged at the input side of the transmission couples and uncouples the torque flow. At least one of the shift clutches is a power-shift clutch with the ability to transmit a greater amount of torque than the other shift clutches. The start-up clutch and the power-shift clutch are controlled by at least one actuator unit.
