Abstract
At least one implementation of a gear shift control system includes an output mechanism coupled to a vehicle transmission, a first drive member coupled to the output mechanism to drive the output mechanism to shift between gears of the transmission and a drivetrain. The drivetrain may include a first input driven by the drive member during a first mode of operation of the gear shift control system and an output coupled to both the first input and the output mechanism to drive the output mechanism as commanded by the drive member. During a second mode of operation of the gear shift control system a second input is coupled to the output. A second drive member is coupled to the second input to drive the output mechanism through the second input and the output during the second mode of operation to cause a transmission gear shift.
