Cruise-O-Matic
Ford-O-Matic was the first automatic transmission widely used by Ford Motor Company. It was designed by Borg Warner Corporation and introduced in 1951 model year cars. The three-speed Ford-O-Matic evolved into the "MX" and "FX" or Cruise-O-Matic transmissions in 1958 and the FMX in 1968. This line continued in production until 1980, when the AOD was introduced. Like Ford, variations of this same Borg Warner design were used by other automobile manufacturers as well, such as AMC, International Harvester, Studebaker, Volvo and Jaguar, each of them having the necessary unique adaptations required for the individual applications.
