The BD Diesel RoadMaster 10R80 transmission kit for 2018–2020 Ford F-150 V8 4WD replaces common-failure OEM components to increase reliability and longevity for stock and lightly modified trucks. It addresses the leaking CDF drum and installs a modified valve body that raises line pressure by approximately 30% for improved clutch holding. The kit includes a deep-sump pan with two extra quarts of fluid to help control temperatures, revised CDF retention, and new OEM clutches and steels for smoother, quicker shifts.
