Abstract
A transmission having engagement mechanisms which employ an engagement inner having cam surfaces forming the race thereof, an engagement outer having a circular outer race and rollers therebetween. A cage mechanism angularly positions the rollers such that they may be wedged between the cam surfaces and the outer race so as to interlock the engagement inner and outer. Actuator mechanisms are employed which are axially movable to engage and angularly position the cages relative to the engagement inner for controlling the engagement mechanism. A plurality of control systems both electronic and mechanical control the operation of the engagement mechanism so as to require substantially synchronous movement between engaging elements. Alternately, nonsynchronous shifting may be accomplished under power for power or rapid shifting. Clutch inhibit may also be employed to prevent premature reengagement of the clutch before shift complete.
