A manual transmission includes a housing having a longitudinal axis and an aperture, and a shift lever assembly comprising a shift lever having a pivot ball. At least three shift lever sockets are coaxially disposed along the longitudinal axis and within the aperture, with each of the at least three shift lever sockets being configured to receive the pivot ball therein when the shift lever is disposed at a corresponding, different discrete longitudinal position along an axis parallel to the longitudinal axis of the housing. A first shift lever assembly comprises a cover plate and a shift tower supporting the shift lever, wherein the shift tower is substantially centered within a periphery of the cover plate. A second shift lever assembly has a shift tower offset from a center of the periphery of the cover plate.
