Put Real Power Behind Your LMM With A Transmission That Can Handle It

If your 2007.5 to 2010 Silverado or Sierra 2500HD or 3500HD 2WD is built around the 6.6L LMM Duramax, then you know just how capable it is from the factory. But when it's time to haul heavy, climb steep, or tow long, your stock transmission can quickly become the weakest link. The ATS Stage 2 Allison LCT1000 Crate Transmission Package is the perfect solution for diesel owners who expect more confidence behind the wheel. This package includes a fully rebuilt ATS LCT1000 transmission, a Five Star torque converter that gives you strong and consistent lock-up, and a deep transmission pan to help manage heat when the pressure is on. You also get the ATS Co-Pilot transmission controller, which means smoother shifts and better control without needing to reprogram your truck. It’s a bolt-in, no-hassle upgrade that delivers real-world benefits you’ll feel from the first drive. Whether you're towing a trailer cross-country or just want your truck to respond the way it should, this transmission package is ready to get to work.

Reinforced Components Designed For Demanding Loads And Smart Control

The ATS 309-822-4332 Stage 2 Transmission Package is engineered for 2007.5–2010 GM 2500HD and 3500HD 2WD trucks running the 6.6L Duramax LMM engine. At its core is a performance-built version of the Allison LCT1000 transmission, featuring upgraded internals to support higher torque output and frequent high-load operation. The included Five Star torque converter provides better torque multiplication with firm lock-up and reduced slippage under acceleration or while pulling heavy loads. A deep transmission pan is added to help manage heat and improve fluid capacity, ensuring your transmission stays protected over long distances or demanding hauls. This system also includes the ATS Co-Pilot transmission controller, which works behind the scenes to enhance line pressure, optimize shift points, and maintain converter lock-up, all without requiring tuning or external programming. Installation is straightforward, and the system ships fully assembled for ease of use. This transmission package is an excellent choice for anyone upgrading power, adding weight, or simply demanding better long-term durability and drivability from their truck. It's a smart mechanical upgrade paired with intelligent control.
