BDD Transmissions

Automatic Transmission Torque Converter

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.
