Description

[shortdesc]

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.

FEATURES

  • Increased clutch torque holding capacity (double capacity for C2 and C4 clutches), for less slip while towing
  • Deep aluminum pan for additional 3.5 quarts of fluid capacity to help keep temperatures lower
  • Billet ProForce torque converter for reliable converter clutch apply
  • Stock clutch counts in transmission
