Abstract
In at least some implementations, a gear shift actuator assembly to cause gear changes in a vehicle transmission includes an electrically operated drive member, a drivetrain driven by the drive member and having a plurality of gears arranged in a plurality of stages to provide a torque increase and a direction change within the drivetrain and an output driven by the drivetrain for rotation to cause a gear change in the vehicle transmission. In some implementations, the torque increase from the motor to the output is between 150:1 and 300:1.
