A second input shaft is in communication with a gear train assembly which is in communication with a propshaft. A selective engagement element is movable between an engagement position wherein the second input shaft is placed in rotational communication with the first input shaft and a disengagement position wherein the second input shaft is disengaged from the first input shaft. An actuator assembly moves the selective engagement element into the engagement position for all wheel drive mode and into the disengagement position for two wheel drive mode.
