A transmission shifting system for axially displacing a jaw clutch (21,23) having a plurality of axially and/or radially beveled teeth (72) for engagement with a plurality of engagement cavities (78) formed in a mainshaft gear (22,24) where a ball ramp actuator (14,16) or a cam ramp mechanism is used to axially displace the jaw clutch (21,23). An electrical coil (32,33) is used to electromagnetically couple a control ring (37,39) to the mainshaft gear (22,24) using a clutch plate (52,53) and an actuation ring (43) is nonrotatably connected to the mainshaft (18). In an alternative embodiment, the actuation ring (90,92) is formed as part of the jaw clutch (94,96) and the control ring (82,83) remains stationary relative to a mainshaft (18). A plurality of flux grooves (80A,80B) are utilized to channel magnetic forces between the clutch plate (84,85) and the mainshaft gear (22,24).
