A two-speed drive unit of an electric vehicle includes a planetary gear set transmission having multiple elements including a first element, a second element and a third element. A motor generator unit supplies a motive force to the planetary gear set transmission. A first stage gear transfers the motive force to the planetary gear set transmission from the motor generator unit. A second stage gear is connected through the second element to a final drive. A first torque transmitting device defining a selectable one-way clutch (SOWC) is connected to the third element.

An automatic transmission with a brake is provided, the brake including a hub member coupled to a transmission case. The hub member includes a first hub member having a cylindrical part spline-engaged with friction plates and the transmission case, and forming a disengagement hydraulic chamber, a second hub member disposed at one side of the first hub member in the axial direction, fitted into the transmission case, and coupled to the one side of the first hub member in the axial direction by a first coupling member, and a third hub member disposed at the other side of the first hub member in the axial direction, coupled to the other side of the first hub member in the axial direction by a second coupling member, and forming an engagement hydraulic chamber.
