BD Diesel 6.6 Duramax LB7 Allison 1000 Transmission | 106470X | 2001-2004 GM/Chevy 6.6L


Elevate the performance and durability of your Duramax with BD Diesel's 2001-2004 GM Duramax LB7 Allison Transmission. Unlike the stock transmission designed for the stock engine, BD transmissions are built to handle high-performance and heavy-duty usage. Equipped with BD's heavy-duty transmission pan, our modifications include adding 20% more friction material than stock, enhancing main line oil pressure for increased clamping force on clutch packs. This ensures your transmission can handle the demands of exhaust braking and diesel engine torque. If you've modified or plan to modify your Duramax, make BD Diesel's transmission your first step for unmatched reliability and performance.
