A modular hybrid transmission that provides for an improved support of the rotor as well as an improved cooling layout for the stator. The modular hybrid transmission has a rotating assembly and a housing assembly. The rotating assembly includes a rotor assembly, a rotor carrier hub that supports the rotor, and an input shaft. The rotor carrier is rotationally fixed on the input shaft. The housing assembly houses the rotating assembly, and includes a housing having an outer wall, a stator assembly connected to the outer wall, and a radially extending stationary wall that extends from the outer wall toward the output shaft. The stationary wall includes an axially extending wall portion that extends parallel to an outer surface of the input shaft, and a radial ball bearing supports the input shaft on this axially extending wall portion. Two stator cooling paths are channeled in the housing.
