Abstract
A change-speed transmission for a motor vehicle. The transmission has a first and second subtransmission, which each have a plurality of shiftable gearwheel sets associated therewith. The subtransmissions each have an input shaft and have a joint output shaft. Each of the input shafts are activated alternatingly by, respectively, a first and a second powershift clutch. A reduction gearing effectuating a transmission change is associated with one of the subtransmissions, and the subtransmissions are alternatingly connected by way of a third powershift clutch.
