Abstract
A manual transmission shifted by synchronizer clutches, in which the transmission gears situated between an input shaft and an output shaft are arranged such that, for the shifting of all forward gears, two clutches respectively are closed. A synchronizer clutch participates in the shifting of all forward gears. By bringing the sliding sleeve of the synchronizer clutch into its neutral zero position, a shifting directly into idling can take place from any shifted gear.
