# BD Diesel 17-19 Chevy/GMC 2500 6.6L L5P Roadmaster Allison Transmission & Converter Package- (4WD)

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, due to a boost in line pressure of up to 68%! BD Allison 1000 transmissions also receive a BD Diesel Deep aluminum pan, for an additional 3.5 quarts of fluid, aiding in cooler transmission temps while towing. Every RoadMaster Allison transmission package includes a ProForce torque converter.
