Superior Overdrive Super Servo Assembly for Ford AOD Transmission 1980-1993

The AOD Overdrive Super Servo Assembly (2.874" OD) is the ultimate upgrade for 1980-1993 Ford AOD and FIOD transmissions. Manufactured from high-strength 6061-T6 billet aluminum, this servo piston offers 11% more apply area than the factory A servo, resulting in dramatically better band holding capacity and firmer 4th gear shifts.

Whether you're rebuilding a daily driver, towing rig, or performance vehicle, this servo directly addresses common AOD issues such as premature overdrive band failure and lack of positive engagement. It installs as a simple drop-in replacement once the valve body is removed and requires no special tools.

Compatible with all non-electronic AOD transmissions from 1980 to 1993.
