It’s not just an upgrade, it’s an investment in how your truck performs every single day. Reinforced Internals And Smart Control For Serious Loads The ATS 309-865-4332 Stage 6 Crate Transmission is designed specifically for 2007.5–2010 GM Silverado and Sierra HD trucks equipped with the 6.6L LMM Duramax and a 4WD PTO configuration. At the heart of this build are billet input, output, and intermediate shafts that provide massive strength gains over stock components. Inside the transmission, a billet P2 carrier, billet C2 hub, and modified P1 sun gear are all engineered to handle high-stress applications and extended use under load. The ATS Five Star torque converter is tuned to multiply torque and reduce slippage, making it ideal for trucks running performance tuning or heavy towing setups. Paired with the ATS Co-Pilot controller, this system dynamically adjusts line pressure and shift strategy to optimize performance and clutch engagement. The deep transmission pan increases cooling capacity and helps maintain consistent temperatures even during long hauls or aggressive driving. This is a purpose-built solution for owners who refuse to compromise when it comes to strength, reliability, and shift quality. From towing to tuning, it’s made to outlast and outperform your expectations.
