Abstract: A shift device with an over-shift lock for a multi-speed transmission of a motor vehicle, in which individual gears are shifted incrementally, is provided. The shift device has a pivotable shifting element which is composed of an activation element and a driver element displaceably held thereon. Both elements have mutually aligned oblong holes which are penetrated by a shifting shaft leading to the transmission. A shifting process is limited by the striking of the shifting shaft against the end sides of the oblong holes. In this position, the alternating influencing of the shifting shaft and the contours of the oblong holes prevents a further rotation of the shifting shaft and thereby an over-shifting of the transmission.
