Abstract

A change gear transmission (12) is provided having an input component (16, 24, 26, 26A, 50, 53, 54 and 56), a connecting component (28, 60, 62, 64 and 80) and an output component (74) and includes a coupling (76) for drivingly connecting and disconnecting the connecting component from the output component. Preferably, the coupling is a positive clutch of the type having relatively low backlash between the interengaging clutch teeth (334, 336, 338, 340) to resist asynchronous engagement thereof.
