The BD Diesel RoadMaster 10R80 transmission and ProForce converter package for 2018–2020 Ford F-150 V8 2WD upgrades vulnerable factory internals to improve reliability and drivability for stock and mildly modified trucks. It remedies leaking CDF drum issues, fits a modified valve body to raise line pressure by about 30%, and includes a ProForce torque converter with refreshed friction material. A deep-sump pan adds two quarts of fluid to help manage transmission temperatures while new clutches and steels deliver smoother shifts.
