If you’ve upgraded your 2011-2016 Duramax or spend your days hauling serious weight, your stock Allison transmission may already be showing signs of stress. The ATS Stage 4 Allison LCT1000 Crate Transmission is built for 2WD Silverado and Sierra HD trucks equipped with PTO functionality, giving you a ready-to-install solution that takes the worry out of heavy-duty use.

Engineered to Tackle the Toughest Demands

Packed with ATS’s proven performance components, this package starts with the Five Star torque converter, designed to improve low-speed drivability and maximize torque transfer when you need it most. The deep transmission pan increases fluid capacity and helps manage heat, keeping your transmission cool and protected under load. You also get the ATS Co-Pilot Transmission Controller, which improves line pressure and shift timing for smoother, more consistent performance in demanding conditions. Inside, billet input and intermediate shafts replace factory weak points, giving your transmission the durability to handle added horsepower and torque without flinching. Perfect for tow rigs, work trucks, or performance builds, this package delivers true peace of mind. Please note, a $500 shipping surcharge applies at checkout.
