Abstract
A transmission includes input and output shafts, a hybrid module coupled to the input shaft and a gearbox coupled to the module and output shaft. The hybrid module includes an electric motor under driven by a gearset; a disconnect clutch coupled to the gearset and selectively to the input shaft; a launch clutch coupled to the disconnect clutch and selectively to a module output; and a vibration absorber coupled with the launch clutch. The gearbox includes three gearsets and five torque transmitting devices operable to generate six forward speeds and reverse. One torque transmitting device is a clutch brake applied with a piston that reaches over a park gear, and another one is a selectable one way clutch. Two of the torque transmitting devices are rotating clutches that are radially stacked. The transmission includes an electric only mode, a hybrid mode and a battery charging mode.
