History
Toledo Propulsion Systems was founded in 1916, and produced truck transfer cases and transmissions for four and six wheel drive trucks for the military throughout World War II. Today, Toledo Propulsion Systems is North America’s most productive rear-wheel drive transmission plant. Toledo has been ranked No. 1 in the Harbour Report nine of the past twelve years. The rear-wheel drive transmissions built in Toledo are shipped to GM’s assembly plants in Arlington, Texas; Bowling Green, KY; Ft. Wayne, Ind.; Flint, Mich.; Wentzville, Mo. and Oshawa, Ontario. The front-wheel drive transmissions are shipped to Fairfax, Kan.; Lordstown, Ohio; Oshawa, Ontario and soon, Lake Orion, Mich.

Toledo Propulsion Systems began as a Warner Gear plant that was purchased in October 1916 located at 900 W Central Ave Toledo.  Toledo has primarily built truck and passenger transmissions throughout its history. The Central Avenue plant continued operations throughout WWII building truck transfer cases and transmissions until a new 414,000 square-foot facility on Alexis Road was acquired from the former Martin-Parry Corporation in 1955.  The original Central Avenue facility ceased operations in 1957 when its equipment was transferred to another Chevrolet facility in Muncie, Indiana and the employees moved to the new Alexis Road facility.  Since 1956 the current facility has been expanded several times and by 1970 was a 1,034,656 square-foot facility producing the Turbo Hydramatic 3 speed automatic transmission employing over 4000 people. In 1982 the Toledo facility began production of the 700R4 which would later be known as the 4L60E transmission and would produce almost 38,000,000 units before its end of production in 2007 making way for new 6L80 and 6T40 transmission production.
