ABSTRACT:
A shifting arrangement for a synchronized motor vehicle transmission with six forward gears and one reverse gear has a longitudinally displaceably and rotatably disposed shifting shaft whose shift fingers can be introduced into mutually aligned grooves of shift tongues for the preselecting of the transmission gears. The shift tongues are pivotally connected to swinging forks which are pivotally arranged in the transmission case and, via their forks, engage in a formlocking manner in sliding sleeves of synchronizer clutches. The shifting fork of the reverse gear is fastened on a shift rod situated perpendicularly to the shifting shaft on which a guide rail is constructed for the longitudinal guiding of the shift tongues.
