The 66RFE transmission suffers from the same component failures as its larger 68RFE sibling, including valve body cross-leaks, worn SSV bore, and overdrive clutch failure. The BD RoadMaster addresses each of these weaknesses with precision-engineered upgrades that enhance both reliability and performance.

This is not a simple rebuild—BD Diesel remanufactures each transmission with upgraded components specifically designed to handle the demands of towing and daily driving.
