A Transmission Built to Match the Strength of Your LBZ

If you’re building power with your 2006 to 2007 Silverado or Sierra HD powered by a 6.6L Duramax LBZ, the factory transmission can quickly become a limiting factor. The ATS Stage 5 Allison LCT1000 Crate Transmission is designed to fix that problem. This setup is engineered for 4WD trucks and includes ATS’s upgraded LCT1000 performance transmission along with their proven Five Star torque converter. The combination is ideal for trucks that are tuned, towing heavy, or seeing more aggressive use than GM ever intended. It provides stronger torque transfer, smoother shifts under load, and the kind of reliability you need when your truck works hard every day.

Smart Components for Power Durability and Control

This Stage 5 package is packed with serious hardware. It features billet input, output, and intermediate shafts that provide increased strength over stock, allowing the transmission to handle high horsepower without compromise. The included deep transmission pan improves cooling, which helps protect the transmission from heat-related failure during heavy use. With the ATS Co-Pilot Transmission Controller, you also get more precise shift strategies and pressure control, making the whole system feel more responsive under throttle. Whether you’re building a reliable workhorse or a performance-driven street truck, this transmission delivers the toughness and control your LBZ Duramax demands.
