A vehicle driveline assembly for an automotive vehicle includes a differential assembly adapted to transfer torque proportionally between first and second axle half-shafts. An over-running clutch is adapted to selectively lock the differential assembly thereby effectively rotationally locking the axle half shafts to one another. The differential has three modes of operation; an open mode, wherein the differential is kept un-locked; a locked mode, wherein the differential is kept locked; and an automatic mode, wherein the differential is locked or un-locked based upon predetermined operating parameters. A selector switch allows an operator to selectively place the differential in one of the three modes. An electronic control unit receives inputs from the vehicle, compares the inputs to pre-determined operating parameters, and selectively engages or disengages the over-running clutch when the differential is in the automatic mode.
