A transmission disconnect clutch assembly and method are provided. The clutch assembly operates to place the transmission in a low-loss state, by decoupling the base transmission from the differential gearing, thereby maximizing fuel economy and increasing efficiency. The transmission disconnect clutch assembly may be a dog clutch assembly, which may include a dog clutch hub, a clutch apply plate, and a synchronizer. When the dog clutch is disengaged the vehicle may operate in EV mode, propelled by an electric motor and rear e-axle. When the dog clutch is engaged the vehicle may operate in hybrid mode, propelled by torque transmitted to a front axle by an engine and the torque transmitted to the rear e-axle by the electric motor. A method for transitioning a vehicle between EV mode and hybrid mode, as well as a method for transitioning a vehicle between hybrid mode and EV mode are also provided.
