Abstract

A shift drum (119) for an automotive transmission comprising a first module (119a) configured to accommodate a pre-selected baseline number of transmission ratios wherein the first module (119a) is provided with connection means (120) for connection with a second module (119b) configured to accommodate one or more transmission ratios above the baseline number of transmission ratios. The shift drum may be included within a transmission for a vehicle such as a motorcycle. The modular construction allows ready assembly of shift drums for a number of pre-determined transmission ratios thereby assisting inventory management at a vehicle assembly plant.
