A Reliable Upgrade for Work-Ready Duramax Builds

If you rely on your 2006–2007 GM 2500HD or 3500HD 4WD with a 6.6L LBZ Duramax and PTO for hauling, plowing, or hard work on the job site, the ATS Stage 1 Allison LCT1000 Crate Transmission is a solid upgrade designed to deliver smoother performance and added durability over stock. It’s purpose-built for trucks that need consistent, dependable shifting without the expense or complexity of a full race setup. At the heart of the package is the upgraded ATS Allison LCT1000 transmission, precision-built for improved internal strength and efficiency. It’s designed to handle daily work duty and towing with ease, giving you the confidence to push harder without worrying about early wear or gear-hunting under load.

Added Cooling, Efficiency, and Torque Converter Performance

What rounds out this package is a carefully matched set of components that work together to support both transmission longevity and consistent drivability. You get the ATS Five Star torque converter, known for delivering stronger lock-up, better torque multiplication, and quicker engagement, especially when towing or under heavy throttle. The deep transmission pan increases fluid capacity, which helps keep transmission temperatures in check—something especially useful when working in hotter climates or pulling uphill for long stretches. This Stage 1 kit is ideal for owners who want a noticeable step up in reliability and performance, but don’t need a full-blown competition setup. It’s built with ATS’s reputation for quality and proven engineering, so you can get the job done with fewer headaches and more confidence behind the wheel.
