|ZF sold the manufacturing rights for the 5 DS-25 Series transaxles to RBT Transmissions, who has since developed the proprietary RBT-6 speed transaxle.
The history of RBT Transmissions began with the dynamic career of Roy Butfoy who was a member of Ford's GT racing team at Le Mans. Roy was later instrumental in setting up Ford's ZF re-manufacturer program during the time Lincoln-Mercury imported the Pantera.
After Roy passed away in 2000, his son, Lloyd Butfoy, ended his 12-year career as a Gearbox Technician with the CART / Indycar series in order to assume control of RBT Transmissions and continue his father's reputable legacy.
RBT Transmissions can expertly rebuild your ZF transaxle according to your needs, from stock to applications with high output racing engines.
