Windsor Transmission is a General Motors of Canada parts plant in Windsor, Ontario and one of several facilities in southern Ontario and Canada. It is the only plant located in southwestern Ontario and is located closer to GM headquarters in Detroit than GM Canada headquarters in Oshawa. It made front-wheel-drive, automatic transmissions and transmission components used by other GM facilities. Built in 1963, the facility closed on July 28, 2010 and will not be re-tooled. This resulted in the layoff of 1,400 workers at the plant. Products produced at this plant have been discontinued, with production of new six-speed transmissions moving to the St. Catharines Engine Plant in St. Catharines, ON.
