To provide a hybrid transmission which reduces an expense of a device, is smoothly started at the start of an engine, enabled in regenerative braking, improves drivability and fuel efficiency, has power from the engine, and has only one motor.

The hybrid transmission includes: a first planetary gear set having a composite planetary gear device which has an input element, a motor generator, and a first clutch which are connected to one another, and includes four or more rotation elements; and a second gear set having a connected output element and includes four or more rotation elements. The first rotation element of the first planetary gear set is always connected to the input element, the first clutch is set to selectively stop the rotation of the third rotation element of the first planetary gear set. The fourth rotation element of the first planetary gear set is always connected to a motor generator.
