The BD RoadMaster E4OD transmission is built for reliability and peace of mind. Designed for stock or mildly modified Ford Super Duty Trucks, the RoadMaster increases durability with a modified valve body. These modifications increase the clutch packs' torque capacity and converter charge pressure. The transmission also receives a BD Diesel Deep aluminum pan, for an additional 6 quarts of fluid, helping to keep transmission temperatures cool while towing. Every RoadMaster E4OD transmission package includes a billet ProForce torque converter and is dyno tested before shipping.
