Abstract

Embodiments which selectively engage a motor with auxiliary equipment and a final drive assembly of the motor vehicle are disclosed. A transmission of such a motor vehicle may include a transmission input shaft to receive power from the motor, a transmission output shaft, and clutches and associated gears that define power delivered by the transmission output shaft based upon power received by the transmission input shaft. An auxiliary gearbox may include a transmission input gear associated with the transmission output shaft, an equipment output gear to power the auxiliary equipment, and a drive output gear to power the final drive assembly. The motor vehicle may further include a transmission control module to engage the transmission input gear with the equipment output gear by transitioning among locking the transmission output shaft, disengaging the clutches to reduce torque on the transmission output shaft, and placing the transmission in an unlocked neutral state.
