ABSTRACT:
A compound transmission (14) comprising an input auxiliary section (18) and a main mechanical change gear transmission (20) is provided. The auxiliary section (18) utilizes friction clutch means (50) having a first and second selectable position for engaging a direct drive or reduction input ratio and a third disengaged position allowing the auxiliary section to provide the torque break function normally provided by a master clutch. Preferably, a positive clutch disconnect (66) is interposed between the friction clutch assembly and the main transmission section (20) to provide reduced main transmission section inertia to provide quicker, easier and and lower energy synchronization of the main transmission.
