Claim:
1. A transmission comprising: a shaft supported for rotation about an axis; an inner race fixed for rotation with the shaft; a gear supported for rotation about the axis; an outer race fixed for rotation with the gear, the outer race defining a cam surface; a non-rotating coil configured to establish a magnetic field in the inner race in response to electric current; and a rocker assembly including a pawl supported in the inner race to pivot between an engaged position and a disengaged position such that contact between the cam surface and the pawl in the engaged position prevents relative rotation between the inner and outer races in at least one direction, a post supported in the inner race to slide between a first and a second position such that in the first position the post forces the pawl into the disengaged position, and a shoe supported by the post and configured to pivot about a pin within the inner race, and with respect to the inner race in response to the magnetic field to slide the post into the second position wherein centrifugal force moves the pawl into the engaged position.
