Upgrade Your 2WD LMM for Real Work and Power

When your 2007.5–2010 Duramax-powered Silverado or Sierra 2500HD/3500HD starts working harder than the factory transmission can handle, the ATS Stage 2 Allison LCT1000 Crate Transmission Package steps in to carry the load. Designed for 2WD models with PTO, this complete package includes ATS’s fully built performance transmission, ready to handle increased torque from towing, hauling, or performance tuning. It comes equipped with ATS’s Five Star torque converter for improved torque transfer and better drivability, especially under load. The deep transmission pan helps keep temperatures in check by increasing fluid capacity, making this package a great fit for work trucks or daily drivers that don’t shy away from heavy use.

Added Control for a Stronger, Smoother Drive

ATS takes this package even further with its Co-Pilot Transmission Controller, giving you more control over shift points and torque converter lock-up. This helps reduce unnecessary heat and wear while keeping your truck responsive and smooth on the road or job site. Whether you use your Duramax for long hauls, heavy loads, or performance upgrades, this package delivers durability and drivability you can trust. It’s a complete, bolt-in solution built for real-world performance and reliability. Just be sure to factor in the $500 freight shipping charge at checkout to complete your order.
