Abstract
A modifiable dual clutch transmission is suggested allowing to be manufactured as two transmission variations having an interdependence of fixed wheels and loose wheels that remains at the same position for both variations while the loose wheels belonging to this interdependence are provided with different diameters for providing different transmission ratios. At least one of the loose wheels in that interdependence is correlated to a different forward gear in one transmission variation compared to the other transmission variation. In both transmission variations the loose wheels relating to the respective interdependences are correlated only to even numbered forward gears or to odd numbered forward gears, preserving the advantage of the dual clutch transmission to shift between two adjacent forward gears without interruption in the tractive power.
