BDD Transmissions

Product Details

The BD RoadMaster Allison transmission is built for reliability and peace of mind. Designed for stock or mildly modified Duramax GM Trucks, the RoadMaster increases durability with a modified valve body. These modifications increase the torque capacity of the clutch packs, including doubling the capacity of the failure-prone C2 clutch! The transmission also receives a BD Diesel Deep aluminum pan, for an additional 3.5 quarts of fluid, helping to keep transmission temperatures cool while towing. Every RoadMaster Allison transmission package includes a billet ProForce torque converter and is dyno tested before shipping.
