A gear tooth of the plurality of gear teeth (52) includes two opposing tooth sides (66,68) extending to a tooth tip (62). The tooth tip (62) defines a radially outboard extent of the gear tooth (52). A first tooth side (66) of the opposing tooth sides (66,68) has a first pressure angle (72), and a second tooth side (68) of the opposing tooth sides (66,68) has a second pressure angle (76) different from the first pressure angle (72).
