Abstract: A transmission system includes a transmission housing and a countershaft having no less than two gears, with the gears defining a plurality of gear ratios. The transmission system also includes a module housing, a first output shaft rotatably coupled to the countershaft, and a second output shaft rotatably coupled to the countershaft. The transmission system further includes a first clutch configured to selectively rotatably couple the first output shaft to the countershaft. The transmission system also includes a second clutch configured to selectively rotatably couple the second output shaft to the countershaft. The transmission system further includes an electric machine configured to deliver rotational power to at least one of the first and second output shafts to deliver rotational power to the countershaft. The countershaft is rotatably coupled to either of the first and second output shafts for all of the gear ratios.
