Abstract
A controller-assisted, manually shifted compound transmission system (10) and range shift control method therefor. Range section (16B) shifts are normally automatically implemented by a range shifter (28) under commands (56) from a controller (54) in response to manual initiation. Under certain operating conditions ((ES.sub.MIN <OS*GR) and (ES.sub.MAX <OS*GR.sub.CLR)) automatic range downshifts without driver initiation are commanded.
