An electronic device for gear selection in an automatic transmission for motor vehicles, comprising a plurality of digital sensors for determining the angular position of rotation of a gear selection shaft emerging from the automatic transmission and rotatable to engage the various gears by a stepping motor operable in both directions, the digital sensors and the stepping motor being electrically connected to a digital electronic operating and control unit which can process coded electrical signals emitted by the plurality of digital sensors as the angular position of the selection shaft varies, a pair of electrical actuators being provided to drive the stepping motor through at least one step at a time in one direction of rotation and/or the other. |
