Built for increased strength and long-term durability, the BD Diesel 1064742 TowMaster Transmission is designed to replace the factory Allison 1000 6-speed in 2006–2007 LBZ Duramax 4WD trucks. Featuring upgraded clutch counts, revised oil circuits, and BD’s heavy-duty aluminum deep sump pan, this dyno-tested transmission is ideal for towing, hauling, or daily driving. This transmission is engineered for drivers who demand more from their drivetrain than the stock unit can offer.
