A coupling and control assembly including a sensor for providing an electrical signal for electronic transmission control is provided. The assembly includes a first coupling member which supports the sensor and a locking element and a second coupling member supported for rotation about a rotational axis. The second coupling member has a coupling face oriented to face radially with respect to the axis and has a set of ferromagnetic or magnetic locking formations. An electromechanical component is also supported by the first coupling member. Both the locking element and the sensor are in close-spaced opposition to the coupling face. The sensor senses magnetic flux to produce an electrical output signal indicative of a speed of rotation of the second coupling member.

A controllable coupling assembly and a coupling member for use in the assembly are provided. The member includes a first coupling face oriented to face axially along a rotational axis and has a set of locking formations angularly-spaced about the axis. The member also includes a second coupling face having a reverse pocket which receives a reverse locking element. The pocket defines a first load-bearing surface adapted for abutting engagement with a load-bearing surface of the reverse locking element. The second coupling face is oriented to face radially with respect to the axis. Each of the set of locking formations defines a second load-bearing surface adapted for abutting engagement with a load-bearing surface of a forward locking element.
A coupling assembly having an overrun mode and a channeled locking member are provided. The locking member has a ramped, open channel extending through a nose and main body of the locking member to an upper face of the main body. The locking member is movable between first and second positions. The first position is a coupling position and the second position is an uncoupling position. Pressurized fluid directed to a bottom of the channel urges the locking member towards the second position upon rotation of a first member of the assembly in a first direction relative to a second member of the assembly above a predetermined RPM to prevent abutting engagement of the locking member with a shoulder of the first member in the overrun mode.
