A transmission assembly may include a first clutch and a second clutch. The second clutch may include a clutch pack, a pressure chamber, a first piston, and a second piston. The first piston may be configured to push against the clutch pack when pressurized fluid is directed into the pressure chamber. The second piston may be configured to push against the first piston when pressurized fluid is directed into the pressure chamber at a time when the first clutch is unactuated and inhibited from pushing against the first piston at a time when the first clutch is actuated. |
