Abstract
A control for enhanced manual shifting in a computer (48) -assisted vehicular compound transmission having a main section (16A) shifted by a manually operated shift lever (31) and an engine fuel controller (36). Engine fueling will be in accordance with the operator-set throttle pedal position (THL) unless the control logic determines that such fueling will prevent acceptable engagement of a target gear ratio (GR.sub.T), in which case engine fueling will be automatically controlled to complete the shift.
