The AOD (for automatic overdrive) is a four-speed automatic transmission with 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.
It was not long ago that if you made big horsepower, it was out of the question to expect an overdrive transmission that would hold up.

The AOD has the neutral safety switch mounted above the valve body on the driver's side of the transmission and the speedometer drive cable is attached to the vehicle speed sensor on the driver's side as well. This transmission uses a throttle valve linkage or cable assembly to regulate the shifts. Because Tom’s Transmissions used a TCI Automotive transmission over-haul kit in Chapter 4, it was decided to use TCI Automotive’s Trans-Scat kit for the 1980–1993 Ford AOD (PN 436000). TCI Automotive offers three Trans-Scat kits for the AOD: Street, Street/Strip, and Heavy Duty.
That is no longer the case, as AODs with hardened one-piece input shafts and other features, like the OD Delete valve body, allow us to build an AOD to safely handle 1500 HP.
Aod Transmission Case
It is not uncommon for over the top, 1000+ HP cars to enjoy the benefits of OD to make street driving a joy- even on the highway- drive it to the track, maybe change the rear tires, and then blast down the 1/4 mile with no concerns of breakage- with or without optional trans-brake.
