Claim 13:
14. A power take-off (PTO) assembly, comprising:
a bi-directional pump in fluidic communication with a hydraulic system of a multi-speed transmission;
a dog clutch that mechanically connects and disconnects the multi-speed transmission from the bi-directional pump; and
a solenoid valve that permits and inhibits fluid flow to an actuation piston in the dog clutch;
wherein when the solenoid valve is energized, fluid flow to the actuation piston is permitted and when a pressure of the fluid applied on the actuation piston is above a threshold value, the actuation piston disengages the dog clutch; and
wherein when the solenoid valve is de-energized, fluid flow to the actuation piston is inhibited and the actuation piston engages the dog clutch.
