Claim 14:
15. A method for operation of a vehicle transmission, comprising:
automatically operating a first disconnect device to mechanically decouple a first drive axle from the vehicle transmission when a pressure in a hydraulic actuation system coupled to the first disconnect device decreases below a threshold value;
wherein the vehicle transmission includes:
a second disconnect device configured to selectively inhibit mechanical power transfer from a second transmission shaft to a second output interface, wherein the second output interface is configured to rotationally couple to a second differential in a second drive axle via one or more mechanical components that extend between the second output interface and the second differential;
wherein the first and second drive axles are spaced away from one another;
wherein the first drive axle includes a first differential that is coupled to axle shafts;
wherein the first disconnect device includes a splined sleeve mated with an output shaft that is directly coupled to an output interface which is configured to rotationally couple to the differential;
wherein the hydraulic actuation system comprises a hydraulic actuator coupled to the splined sleeve;
wherein the hydraulic actuator is configured to axially translate the splined sleeve in opposing directions to place the hydraulic actuator in an engaged configuration and a disengaged configuration; and
wherein the first disconnect device and the second disconnect device are both commonly enclosed in a transmission housing.
