Strengthen Your Drivetrain for Towing and Performance
If you rely on your 2007.5–2010 GM Silverado or Sierra 2500HD or 3500HD with a 6.6L LMM Duramax for towing, hauling, or running performance upgrades, the ATS Stage 2 Allison LCT1000 Crate Transmission is designed to take your truck to the next level. This complete package includes ATS’s fully built performance transmission designed specifically for 4WD trucks equipped with a PTO. It comes with their proven Five Star torque converter to improve low-end response and torque delivery, along with a deep transmission pan that increases fluid capacity for better cooling. Together, these upgrades help your truck stay reliable and responsive under heavy load or demanding driving conditions.
Better Control, Cooler Temps, and Long-Term Durability
The package also includes the ATS Co-Pilot Transmission Controller, giving you precise control over torque converter lock-up and shift timing to maximize performance and minimize heat. This controller works hand-in-hand with the upgraded hardware to keep your transmission operating smoothly, whether you’re pulling a trailer up a mountain pass or putting extra power to the ground. Built to handle real-world use and the added strain of tuned power levels, this Stage 2 transmission package gives you the peace of mind that your driveline is ready for the job. Don’t forget, this product ships via freight, and a $500 shipping fee will apply at checkout.
