Willow Run Transmission (also called Ypsilanti Transmission Operations, YTO) was a General Motors factory in Ypsilanti Township, Michigan. [1] Acquired by GM in 1953, it produced Hydramatic and other automatic transmissions for use in vehicles built by General Motors and other automakers. The factory first opened in 1941 as the Ford Willow Run facility, which built B-24 Liberator bombers during World War II, and its original building (still preserved within the fabric of the GM Powertrain plant) was designed by noted architect Albert Kahn.
Following the war, the bomber plant was sold as surplus property to the Kaiser-Frazer Corporation, a partnership of construction and shipbuilding magnate Henry J. Kaiser and Graham-Paige executive Joseph W. Frazer. From 1947 to 1953, Willow Run built Kaiser and Frazer cars for Kaiser-Frazer and its successor Kaiser Motors. Kaiser also produced cargo planes during the Korean War at Willow Run under license from Fairchild Aircraft, including the C-119 Flying Boxcar.
The Willow Run factory was acquired by General Motors in late 1953, after the Detroit Transmission plant in Livonia, Michigan, which held GM's only Hydramatic production line, burned down in mid-August; the line was up and running at Willow Run a mere nine weeks after the fire. [2] The plant grew over the years from the 3,500,000 square feet (330,000 m2) bomber plant to the nearly 5,000,000 square feet (460,000 m2) GM Powertrain factory and engineering center that the company abandoned as part of its 2009 bankruptcy. A parcel of land south of the Powertrain facility became Willow Run Assembly, which produced cars until 1992, later being sold by GM and becoming the Willow Run Business Center. [3]
In addition to making automatic transmissions, Willow Run Transmission also produced the M16A1 rifle and the M39A1 20mm autocannon for the U.S. military during the Vietnam War. [4]

On June 1, 2009, GM announced it would be closing the plant as part of its bankruptcy proceedings. [5] [6] The plant was transferred to Motors Liquidation Company, and transmission production ended on December 15, 2010. [7] The RACER Trust, which was charged with cleaning up and discharging with old GM properties, has controlled the property since March 2011, and received among other proposals an offer from A.E. Equities Group Holdings to buy the plant in 2011. [8]
In April 2013, the Detroit Free Press confirmed that the RACER Trust was negotiating with the Yankee Air Museum, which had until August 2013 to raise the funds needed to purchase a portion of the original bomber plant, which became part of what was Willow Run Transmission. The museum would consolidate operations scattered on various parcels around Willow Run, and the trust expected to clear the remainder of the Powertrain plant for redevelopment. [9]

Kaiser Motors Corporation made automobiles at Willow Run, Michigan, United States, from 1945 to 1953. In 1953, Kaiser merged with Willys-Overland to form Willys Motors Incorporated, moving its production operations to the Willys plant at Toledo, Ohio where they continued to build automobiles under the Kaiser marque including the Kaiser Darrin until 1955. Their South American operations continued to build passenger cars well up into the 1960s. The company changed its name to Kaiser Jeep Corporation in 1963.
Albert Kahn was an American industrial architect. He was accredited the architect of Detroit and designed industrial plant complexes such as the Ford River Rouge automobile complex. He designed the construction of Detroit skyscrapers and office buildings as well as mansions in the city suburbs. He led an organization of hundreds of architect associates and in 1937, designed 19% of all architect-designed industrial factories in the United States. Under a unique contract in 1929, Kahn established a design and training office in Moscow, sending twenty-five staff there to train Soviet architects and engineers, and to design hundreds of industrial buildings under their first five-year plan. They trained more than 4,000 architects and engineers using Kahn's concepts. In 1943, the Franklin Institute posthumously awarded Kahn the Frank P. Brown Medal.
Willow Run, also known as Air Force Plant 31, was a manufacturing complex in Michigan, United States, located between Ypsilanti Township and Belleville, built by the Ford Motor Company to manufacture aircraft, especially the B-24 Liberator heavy bomber.

The GMC Motorhome is a recreational vehicle that was manufactured by the GMC Truck & Coach Division of General Motors for model years 1973–1978 in Pontiac, Michigan, USA — as the only complete motorhome built by a major auto/truck manufacturer.

Hydramatic is an automatic transmission developed by both General Motors' Cadillac and Oldsmobile divisions. Introduced in 1939 for the 1940 model year vehicles, the Hydramatic was the first mass-produced fully-automatic transmission developed for passenger automobile use.
The Powerglide is a two-speed automatic transmission designed by General Motors. It was available primarily on Chevrolet from January 1950 through 1973, although some Pontiac models also used this automatic transmission after the fire at the Hydra-Matic factory in 1953. Powerglides were used extensively on Pontiacs produced for the Canadian market with Chevrolet powertrains. They were also used with Nova engines in the DJ-5A Jeeps produced 1968-1970 by Kaiser-Jeep and widely used as delivery vehicles by the United States Post Office. When introduced on upper-level Chevrolet models in 1950, the Powerglide represented the first automatic transmission offered in a low-priced automobile; in contrast, Ford did not offer their automatic transmission until 1951, while Plymouth car buyers had to wait until 1954. The transmission was simple and very durable, which satisfied customers.
The Kaiser-Frazer Corporation was the result of a partnership between industrialist Henry J. Kaiser and automobile executive Joseph W. Frazer. In 1947, the company acquired the automotive assets of Graham-Paige, of which Frazer had become president near the end of World War II. Kaiser-Frazer was one of a few US automakers to achieve success after World War II, if only for a few years. Joseph W. Frazer left the company in 1949, replaced as president by Henry's son Edgar F. Kaiser.

It features clutch to clutch shifting, eliminating the one-way clutches used on older transmission designs. In February 2006 GM announced that it would invest $500 million to expand the Toledo Transmission plant in Toledo, Ohio to produce the 6L80 in 2008. Torque rating 440 ft/lb. 6L90 1220ft/lb.

It was also adopted by Rolls-Royce in 1991 and modified after extensive testing, and used initially in the Bentley Continental R, and subsequently other Rolls-Royce and Bentley vehicles. The 4L80 and 4L85 were built at Willow Run Transmission in Ypsilanti, Michigan.
The 4T80E is a series of automatic transmissions from General Motors. Designed for transverse engine configurations, the series includes 4 forward gears. The 4Txx family is an evolution of the original Turbo-Hydramatic 125 transverse automatic introduced in the 1980 model year "X" body.
