Abstract
In the case of a synchronized manual transmission of a motor vehicle, the transmission gears, which consist of loose wheels and fixed wheels, can be shifted by means of the coupling of the loose wheels with their pertaining transmission shafts. The transmission gears are arranged such between an input shaft and an output shaft that they can be shifted only by the simultaneous closing of two synchronizer clutches which are assigned to them.
