  • Publication number: 20080302203
    Abstract: The invention relates to a shift lever arrangement for a transmission of a motor vehicle having a shift lever for setting a selected shift stage of the transmission, with the shift lever being mounted, by means of a positioning unit, so as to be movable between a non-use position of the shift lever and a use position thereof for setting the shift stages and/or vice versa, wherein an anti-trap unit is assigned to the shift lever, in such a way that, after the activation of the positioning unit for adjusting the shift lever between the non-use position and the use position thereof and/or vice versa, the positioning force generated by the positioning unit and acting on the shift lever can be at least reduced.

  • Publication number: 20080264193
    Abstract: A shift device for a transmission of a motor vehicle has a shift lever that can be moved into different shift positions, an actuating unit that, as a function of the shift position of the shift lever, generates a shift signal for transmitting to an electric transmission control unit, and an electric transmission control unit that, as a function of the shift signal of the actuating unit, sends an electric activation signal to a shift element of the transmission in order to set the desired shift stage. The actuating unit includes a restoring element or restoring elements operating in such a way that the shift lever, after reaching the selected shift position, is always moved automatically into a predefined starting position.
