The shifting unit includes a cam block connected to a first driven gear engaged with the drive gear and having a cam surface on an exterior circumference for shift-stages for controlling gear shifting. In addition, the parking unit includes a parking gear and a parking sprag having an engagement end for controlling engagement and disengagement of a parking state.
