Common card · No. 344043

The AOD (automatic overdrive) is a four-speed automatic transmission, with the 4th gear as overdrive. Introduced in 1980, it was Ford's first four-speed automatic overdrive transmission. The gearset design is based on the Ford "X" automatic transmissions used during the 1950s, '60s, and '70s. The AOD replaced many of Ford's older transmissions, such as the C4, C5, and light duty applications of the FMX.
