A transfer case (26) for translating rotational torque from an engine (22) to first and second differentials (34, 36). A primary shaft (50) is supported in a housing (48) and has an input in communication with the engine (22) and an output in communication with the first differential (34). A secondary shaft (52) is disposed in communication with the second differential (36). A clutch (54) selectively translates torque between the shafts (50, 52) and moves between a first position (54A) wherein torque is translated to the secondary shaft (52), and a second position (54B) wherein torque is interrupted. An actuator (64) with a piston (68) movably supported in a cylinder (66) moves the clutch (54). A lock (70) moves between a locked configuration (70A) engaging the piston (68) to prevent the clutch (54) from moving, and an unlocked configuration (70B) releasing the piston (68) allowing the clutch (54) to move.
