Built For Torque Tested For Abuse Trusted For Power The ATS 309-864-4308 Stage 6 Transmission is specifically engineered for 2006–2007 GM Silverado and Sierra 2500HD/3500HD models equipped with the 6.6L Duramax LBZ and 4WD. Inside the case, you’ll find a trio of billet shafts, input, output, and intermediate, all built to handle the elevated torque loads produced by tuned and towing-focused engines. The billet P2 carrier and billet C2 hub, combined with a modified P1 sun gear, work together to strengthen the transmission’s gearset, improving durability during hard launches and sustained hauling. The included ATS Five Star torque converter boosts torque multiplication and reduces slippage, while the deep transmission pan increases fluid capacity for cooler, more stable operation. The system is controlled by ATS’s Co-Pilot controller, which provides adaptive shift strategies and smarter line pressure management to protect clutches and improve response. This crate transmission is ready to install, offering factory fitment with a massive performance edge. Whether you’re building for pulling power or tuning for fun, this setup delivers the control and strength your LBZ platform demands.
