1. An electronic vehicular transmission comprising:
a transmission case having an environment hostile to electrical components; a coupling member supported for rotation within the environment 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 capable of operating in the environment, the component including a mechanical locking element, at least excitation coil and electrical wiring to supply electrical power to the at least one excitation coil from a power source outside the environment, the component being mounted to and extending into the environment of the case so that the locking element is in close-spaced opposition to the coupling face and the wiring is segregated from the environment to resist long-term, hot temperature embrittlement and fragmentation of insulation on the wiring, the locking element being movable across a gap towards the coupling face to a coupling position in response to the at least one excitation coil receiving electrical power, 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. |
