1965–1966 Mustang AOD Automatic Overdrive Conversion Kit
Part Number: TRA-656-402
Upgrade your 1965–1966 Ford Mustang from a C4 or C6 automatic transmission to a modern Ford AOD automatic overdrive transmission for improved drivability and reduced highway RPM. This AOD conversion kit from California Pony Cars is engineered to take the guesswork out of the swap by supplying the critical components required to install a 1980s-era Ford AOD transmission behind 289, 302, or 351W small block Ford engines.
This kit is specifically designed for Mustangs equipped with aftermarket Holley-style carburetors, ensuring proper throttle valve (TV) pressure, correct shift timing, and long AOD transmission life.
What Is Included in This Mustang AOD Conversion Kit
