Abstract

Abstract A gear selector mechanism for automatic transmissions with a gear lever connected to the gearbox and movable in a selector gating for setting the correct gear position. The selector gating is connected to the gearbox in such a manner that the movements of the gearbox are transmitted uniformly to the gear lever and the gating, whereby their relative positions remain unchanged.
