Abstract
An actuation system for a transmission synchronizer, including a first member and a second member, the second member being pressed against the first member for synchronization of two relatively rotating elements, includes a variable pressure type actuator which selectively presses the second member against the first member, with a pressing force which is controllable to vary over a range so as to press the second member against the first member at a lower pressure in the initial phase of synchronization and at a substantially increased pressure at the end of synchronization.
