Proven Strength for High-Horsepower and Heavy Towing Builds

If your 2011-2016 LML Duramax is tuned for big power or sees constant heavy towing, the ATS 309-854-4362 Stage 5 Allison LCT1000 Crate Transmission is built to handle the challenge. Designed specifically for 4WD Silverado and Sierra 2500HD and 3500HD trucks, this complete package includes ATS’s fully built LCT1000 performance transmission. It comes paired with their proven Five Star torque converter to improve torque transfer and reduce slippage under heavy load. The deep transmission pan helps keep temperatures in check during long hauls or high-performance driving, while the ATS Co-Pilot transmission controller gives you more control over shift timing and line pressure for smoother, more responsive operation.

Engineered to Withstand Extreme Torque and Abuse

What makes this Stage 5 package stand out is its internal billet shaft upgrades. The billet input, output, and intermediate shafts provide the strength needed to handle the stress of aggressive tuning, oversized tires, heavy trailers, and high-horsepower builds. These critical reinforcements help prevent failure where stock components often fall short. The package is designed as a direct bolt-in replacement, making it a perfect fit for serious builders and daily drivers alike. Whether you’re working your truck to the limit or chasing peak performance, this ATS transmission package delivers durability you can count on. Just note that a $500 shipping surcharge applies at checkout, reflecting the premium components and freight involved in delivering this fully assembled powerhouse.
