1. A hybrid transmission for a vehicle, the hybrid transmission comprising:
a transmission input shaft extending in a transverse direction;
at least one countershaft arranged parallel to the transmission input shaft;
a clutch device arranged coaxially with the transmission input shaft and having at least one clutch;
a differential having a differential input gear, wherein a rotational axis of the differential input gear is arranged parallel to the transmission input shaft;
an electric machine having a rotor and a stator, wherein a rotor rotational axis is arranged parallel to the transmission input shaft; and
a transmission control device,
wherein, as viewed in a longitudinal direction arranged perpendicular to the transverse direction, the differential input gear, the transmission input shaft, and a transmission controller comprising the transmission control device are arranged in succession in the recited sequence,
wherein at least one part of a power electronics system for the electric machine is arranged adjacent to the transmission control device in a vertical direction, which is arranged perpendicular to the transverse direction and perpendicular to the longitudinal direction,
wherein the electric machine is arranged adjacent to and above a hydraulic transmission controller in the vertical direction and overlapping the hydraulic transmission controller in the longitudinal direction, and
wherein a further part of the power electronics system extends in the longitudinal direction and is arranged above the electric machine in the vertical direction.
