The Upgrade Your Duramax Transmission Deserves

When you push your LML Duramax to work harder—whether that’s through tuning, heavy hauling, or daily commercial use—the factory Allison transmission can quickly become the weak link. The ATS 309-833-4362 Stage 3 Allison LCT1000 Crate Transmission gives you a complete solution designed to handle higher torque and tougher workloads. This package is specifically built for 2WD, PTO-equipped trucks and comes fully assembled with ATS’s performance-built transmission. It features the proven Five Star torque converter for smooth, reliable power transfer, and a deep transmission pan to increase fluid capacity and help reduce operating temperatures. It’s the perfect setup for drivers who want to maintain reliability while putting their trucks to work.

Complete Package with Advanced Control and Proven Strength

Beyond the core upgrades, ATS includes their Co-Pilot Transmission Controller to give you more control over shifting and torque converter lock-up, helping reduce wear while improving drivability under load. The billet input shaft provides added durability where it matters most, making this transmission capable of handling increased horsepower and heavy-duty towing without breaking down. ATS also makes the process simple with a flat $500 shipping fee that covers both delivery and return of your core transmission. If you’re looking to replace your worn-out factory unit with something that’s built to perform and last, this Stage 3 package has everything you need to get back on the road with confidence.
