Abstract
In a twin-clutch transmission, in a first forward gear, the drive torque is transferred by an interconnection of a first transmission part having one countershaft and a second part transmission having another countershaft by means of an intermediate stage whose gearwheels can be used multi-functionally in connection with additional forward gears of the transmission thereby providing for a relatively small transmission with a relatively large number of transmission ratios.
