Abstract

A shifting arrangement for an automatic transmission of a motor vehicle controlled by an electronic control apparatus includes a selector lever to be operated manually. By displacement of the selector lever in a first shifting lane, the different transmission speeds can be selected. After shifting the shifting lever by way of a transverse lane into a second shifting lane, the desired forward speed can be manually engaged by means of the same. The shifting operation is picked up by means of a sensor which influences a shifting unit. The shifting unit effects the maintenance of an actually engaged transmission speed during a change of the shifting lane.
