Claim:
1. An electronic vehicular transmission comprising: a transmission case; a controllable coupling assembly including a coupling member supported for rotation within the case about a rotational axis, the coupling member having a coupling face oriented to face radially with respect to the axis and having a set of locking formations; and an electromechanical component including a locking element and a sensor, the component being mounted to and extending into the case so that both the locking element and the sensor are in close-spaced opposition to the coupling face, the locking element being movable across a gap towards the coupling face to a coupling position in response to the component receiving an electrical control signal, the locking element abuttingly engaging one of the locking formations to prevent rotation of the coupling member in one direction about the axis in the coupling position, the sensor sensing magnetic flux to produce an electrical output signal indicative of a speed of rotation of the coupling member wherein a variable magnetic field is generated in response to rotation of the locking formations past the sensor.
