It was mainly intended for the new Modular V8 at first, but it was also adapted to the old AOD bell-housing for vehicles still powered by pushrod engines. The AOD was redesigned with electronic controls in 1992, becoming the AOD-E. Initially called XT-LOD (Extension Lock-Up Overdrive) its name was changed when revisited in 1974 to FIOD (Ford Integrated Overdrive) and then to its final name in 1979, the Ford AOD transmission.
USED FORD AOD TRANSMISSION FOR SALE FULL SIZE
The transmission was introduced when Ford started to downsize its full size line in 1979. The project was shelved with a design that lacked a dampener in the torque converter but after the project was revisited a dampener ultimately made its way into the final design. The XT-LOD was initially abandoned in 1966 but design began again in 1974 as a result of rising gas prices. The transmission featured a split-torque application for third gear as well as a lockup in the torque converter. Because it was based on the "X" transmissions, its gear ratios from 1-3 were the same with the fourth being 0.67:1. Where many transmissions had a fourth gear added on as an afterthought, Ford's new transmission was designed with a fourth gear integrated into the gearset. The new transmission was built around the Ravigneaux planetary gearset of the "X" transmissions. In 1962 Ford began working on a new type of automatic transmission that would emphasize fuel economy and driveability.
