Abstract
At least some implementations of a gear shift control system include first and second drive members, a drivetrain selectively driven by the first and second drive members and a retainer. The drivetrain includes a first input driven by the first drive member, a second input and an output coupled to and selectively driven by both the first input and the second input. The second drive member is coupled to the second input to drive the output through the second input during a second mode of operation to cause a transmission gear shift. The retainer is selectively coupled to the second input and movable between first and second positions to permit movement of the second input during the second mode of operation and prevent such movement during a first mode of operation.
