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.
