Abstract

A shifting arrangement for an automatic transmission has a selector lever guided in a shifting channel by which various transmission gears can be preselected. The forward gears can be shifted by hand by a manual gear selecting device. The gear selecting device is arranged on the selector lever or is constructed, for example, as a steering column switch. An electronic control unit controls the automatic as well as the manual gear selection.
