The hybrid transmission (10) includes a first sub-transmission (10a) with multiple gear steps and a first transmission input shaft (12), a second sub-transmission (10b) with multiple gear steps and a second transmission input shaft (14), a countershaft (16), multiple shift elements (A, B, C, D, E) for engaging the gear steps (1, 2, 3, 4, 5), and gearwheel pairs of idler gears (28, 32, 36, 40, 44) and fixed gears (26, 30, 34, 38, 42) for forming the gear steps, arranged in multiple gear set planes. A portion of the gear steps is engageable for the internal combustion engine, and a portion of the gear steps is engageable for the electric prime mover. The gearwheel pairs for forming the gear steps having the lowest and the second-lowest ratios are fixedly associated with the first sub-transmission.

A transmission includes a main shaft having two or more main shaft clutches that couple gears to at least one countershaft, and an automated manual transmission coupled to the main shaft via the at least one countershaft. The automated manual transmission includes a front input shaft coupled directly to a main clutch and having a first clutch coupleable to the at least one countershaft, and a rear input shaft coupled to the front input shaft and having a second clutch coupleable to the at least one countershaft. The automated manual transmission is operable to selectively engage the first clutch and the second clutch.

Provided is a dual clutch transmission for an internal combustion engine including a motor generator unit, MGU (M), for providing electric or hybrid driving capability wherein the MGU (M) is selectively connectable to a (one) transmission input shaft, or transmission output shaft or to neither shaft.
