The Ford transmission system holds almost 18 quarts of ATF, and you must waste a couple of quarts to be sure you get it all purged and replaced, so buy 20 quarts of MERCON ATF.
Automatic transmission fluid
Customary units in the United States
Automatic transmission fluid (ATF) is the fluid used in vehicles with self shifting or automatic transmissions. It is typically colored red or green to distinguish it from motor oil and other fluids in the vehicle. On most vehicles its level is checked by a dipstick while the engine is running.
The fluid is a highly specialized oil optimized for the special requirements of a transmission, such as valve operation, brake band friction and the torque converter as well as gear lubrication.
United States customary units are a system of measurements commonly used in the United States. The U.S. customary system developed from English units which were in use in the British Empire before American independence. Consequently most U.S. units are virtually identical to the British imperial units. However, the British system was overhauled in 1824, changing the definitions of some units used there, so several differences exist between the two systems.
The majority of U.S. customary units were redefined in terms of the meter and the kilogram with the Mendenhall Order of 1893, and in practice, for many years before. These definitions were refined by the international yard and pound agreement of 1959. The U.S. primarily uses customary units in its commercial activities, while science, medicine, government, and many sectors of industry use metric units. The SI metric system, or International System of Units is preferred for many uses by NIST

The system of imperial units or the imperial system (also known as British Imperial) is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but some Imperial units are still used in the United Kingdom and Canada.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is a federal law enforcement organization within the United States Department of Justice. Its responsibilities include the investigation and prevention of federal offenses involving the unlawful use, manufacture and possession of firearms and explosives; acts of arson and bombings; and illegal trafficking of alcohol and tobacco products. The ATF also regulates via licensing the sale, possession, and transportation of firearms, ammunition, and explosives in interstate commerce. Many of ATF's activities are carried out in conjunction with task forces made up of state and local law enforcement officers, such as Project Safe Neighborhoods. ATF operates a unique fire research laboratory in Beltsville, Maryland, where full-scale mock-ups of criminal arson can be reconstructed.
The agency is led by B. Todd Jones, Director, and Thomas E. Brandon, Deputy Director. ATF has 4,770 employees, and an annual budget of $1.2 billion (2012).
The Ford Motor Company (also known as simply Ford) is an American multinational automaker headquartered in Dearborn, Michigan, a suburb of Detroit. It was founded by Henry Ford and incorporated on June 16, 1903. The company sells automobiles and commercial vehicles under the Ford brand and luxury cars under the Lincoln brand. In the past it has also produced heavy trucks, tractors and automotive components. Ford owns small stakes in Mazda of Japan and Aston Martin of the United Kingdom. It is listed on the New York Stock Exchange and is controlled by the Ford family, although they have minority ownership. It is described by Forbes as "the most important industrial company in the history of the United States."
Ford introduced methods for large-scale manufacturing of cars and large-scale management of an industrial workforce using elaborately engineered manufacturing sequences typified by moving assembly lines; by 1914 these methods were known around the world as Fordism. Ford's former UK subsidiaries Jaguar and Land Rover, acquired in 1989 and 2000 respectively, were sold to Tata Motors in March 2008. Ford owned the Swedish automaker Volvo from 1999 to 2010. In 2011, Ford discontinued the Mercury brand, under which it had marketed entry-level luxury cars in the United States, Canada, Mexico, and the Middle East since 1938.
