Put an End to Weak Links in Your Drivetrain

If you’ve pushed your LBZ Duramax past stock power or spend your days towing heavy loads, you know how quickly a factory transmission can become a liability. The ATS 309-832-4308 Stage 3 Allison LCT1000 Crate Transmission is built to fix that problem with a package designed to handle the demands of real work. Built specifically for 2WD Duramax trucks, this transmission package includes ATS’s performance-enhanced Allison LCT1000, their Five Star torque converter for improved torque transfer, and a deep transmission pan that increases fluid capacity to help manage heat. Whether you’re hauling equipment, pulling a camper, or just want better peace of mind on the road, this package gives your truck the backbone it needs to keep going strong.

Complete Control and Built-In Strength Where It Counts

What makes this package truly complete is how it improves both durability and drivability. ATS includes their Co-Pilot Transmission Controller, giving you better control over shift timing and torque converter lock-up so your truck responds better under load without unnecessary strain. A billet input shaft comes standard, providing the extra strength needed for higher torque demands or heavy-duty towing. This package ships as a fully assembled, ready-to-install unit, and ATS simplifies the process with a $500 flat-rate shipping fee that covers both delivery and core return. If you’re ready to replace your worn-out factory transmission with something proven to perform, this Stage 3 package is built to keep your truck working as hard as you do.
