Detent dependent on driving speed for preventing inadmissible selection positions of a manually actuable selection-setting shaft of a shift device of a gear-change transmission

摘要

In an automatic shift device of a gear-change transmission, that selection position, associated with forward gears, of a manually actuable selection-setting shaft which could trigger a shift back to too low a gear in relation to the instantaneous driving speed is blocked by means of a setting piston working as a function of the driving speed.
