An apparatus and technique which assists a driver in manually shifting gears is disclosed. Gears are selected through lateral and longitudinal movements of a shift linkage. Lateral movements cause the shift linkage to move between first extreme, intermediate, and second extreme positions. A first actuator coupled through a control rod and a shift lever loop to the shift lever. A blocking member is positioned on the control rod to engage a shaft of a second actuator when the shift linkage is in its intermediate position. Activation of the first actuator causes the shift linkage to move laterally to its first extreme position. When the second actuator is deactivated, deactivation of the first actuator causes the shift linkage to move laterally to its intermediate position under a spring-applied force. When the second actuator is activated, deactivation of the first actuator causes the shift linkage to move laterally to its second extreme position. The shift lever loop slidably couples to the shift linkage in the longitudinal dimension. Thus, the lateral movements urged by operation of the actuators have substantially no influence on longitudinal shift linkage movements, which may be imposed manually.
