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.

Shifting arrangement for a motor vehicle transmission

A shifting arrangement of an automatic transmision of a motor vehicle has a selector lever which can be pivoted in two shifting paths. In the first shifting path of the selector lever, various operating positions and automatically shifting gears of the transmission may be selected via a transmitting device. The selector lever can be changed over into a second shifting path in which, by a one-time pivoting of the selector lever from a center position, an upshifting or return shifting may take place by one gear respectively. A locking device interacts with the transmitting device so that the transmitting device, from which the selector lever is separated in the second shifting path, is held in its intended position.

Shifting arrangement for an automatic transmission of a motor vehicle

A shifting arrangement for an automatic transmission of a motor vehicle controlled by an electronic control apparatus includes a shifting lever to be manually actuated. By pivoting the shifting lever in a first shifting lane, the different transmission speeds can be selected. After shifting the shifting lever by way of a cross lane into a second shifting lane, the desired forward speed can be manually engaged by means of the same.
