ABSTRACT:
A shifting arrangement for an automatic transmission of a motor vehicle controlled by an electronic control unit has a selector lever, the pivoting of which into a first shifting path, allows driving positions to be preselected, each driving position having various transmission gears which are to be shifted automatically. If the selector lever, by way of a transverse path, is changed over into a second shifting path which is parallel to the first shifting path, the transmission gears may be shifted manually by a pivoting in the second shifting path. In order to ensure a stable and vibration-free bearing of the shifting arrangement, the selector lever is disposed in a hollow frame which includes a pot-shaped bottom part made of a light metal casting and a cover plate screwed to the top of the bottom part.
