1. A two-speed electrified transmission system, comprising:
an electric motor driving an input shaft, wherein the input shaft is rotationally coupled to a first gear that meshes with a first clutch gear;
a first wet clutch positioned on a first end of a countershaft to selectively engage the countershaft with the first clutch gear;
a second wet clutch positioned on a second end of the input shaft to selectively engage the input shaft with a second clutch gear, wherein the input shaft meshes with the second clutch gear and the countershaft meshes with the first clutch gear; and
an output shaft rotationally coupled to the countershaft.
