Description

ROADMASTER TRANS PKG

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.
