Ford Mustang
Engines for the 1974 models included the venerable 2.3 L I-4 from the Pinto and the 2.8 L Cologne V6 from the Mercury Capri. The 1975 model year reintroduced Windsor V8 that was only available with the C-4 automatic transmission, power brakes, and power steering. This continued through production end in 1978. Other transmissions were the RAD 4-speed with unique gearing for all three engines, and the C-3 automatic behind the 2.3 L and 2.8 L. The 5.0 L designation was not applied until the 1978 King Cobra model. All 302 equipped Mustang II's, except the King Cobra received an updated version of the classic Ford "V8" emblem on each front fender.
Automatic transmission
The automatic transmission was invented in 1921 by Alfred Horner Munro of Regina, Saskatchewan, Canada, and patented under Canadian patent CA 235757 in 1923. (Munro obtained UK patent GB215669 215,669 for his invention in 1924 and US patent 1,613,525 on 4 January 1927). Being a steam engineer, Munro designed his device to use compressed air rather than hydraulic fluid, and so it lacked power and never found commercial application. The first automatic transmission using hydraulic fluid may have been developed in 1932 by two Brazilian engineers, José Braz Araripe and Fernando Lehly Lemos; subsequently the prototype and plans were sold to General Motors who introduced it in the 1940 Oldsmobile as the "Hydra-Matic" transmission. They were incorporated into GM-built tanks during World War II and, after the war, GM marketed them as being "battle-tested." However, a Wall Street Journal article credits ZF Friedrichshafen with the invention, occurring shortly after World War I. ZF's origins were in manufacturing gears for airship engines beginning in 1915; the company was founded by Ferdinand von Zeppelin.
