The normal smooth shifting associated with Ford transmissions produces heat and advanced wear that severely shortens life. BD has examined the mechanical design of Ford transmissions and studied the shift strategy to identify ways to improve the durability and driving experience.
This research effort has led to BD’s development of transmission and convertor clutches that are mechanically and pneumatically designed not to slip. The new shift strategy change results in "Quick Sharp Shifts".
Enhancements to achieve this include new control valve designs, higher pressures as well as improved internal oil flow enhancements of the existing port sizes. Additional oil passages have been added to route the oil to assist the current Ford splash lubrication design.
Torque load capacity was improved by adding 33% more clutch surface to each of the 4 clutch packs. The planetary gear packs are special high strength steel and the new heavy duty roller one way Sprague clutches maintain directional stability and don't explode.
