If your LB7 Duramax is starting to slip, shift rough, or struggle under heavy towing, it might be time to stop patching the problem and upgrade to a solution that’s built to last. The ATS 309-832-4272 Stage 3 Allison LCT1000 Crate Transmission gives your 2WD Duramax a complete drivetrain refresh, designed to handle real-world demands. This package includes ATS’s fully rebuilt and upgraded Allison LCT1000 transmission, their proven Five Star torque converter for smooth torque delivery, and a deep transmission pan that boosts fluid capacity to help manage heat. Whether you use your truck for hauling loads, towing trailers, or just want better durability for daily driving, this transmission package delivers the strength and cooling your factory unit lacks.

Complete Package with Added Strength and Shift Control

ATS goes a step further by including their Co-Pilot Transmission Controller, which gives you better control over shift quality and torque converter lock-up, improving drivability when your truck is under load. It also comes with a billet input shaft to reinforce one of the most failure-prone parts of the Allison, giving you peace of mind when the torque starts climbing. ATS makes the process easy by offering a $500 flat-rate shipping fee that covers both the delivery of your new transmission and the return of your core. If you’re ready to stop worrying about transmission problems and start enjoying the reliability your truck deserves, this Stage 3 package is the right choice to get you back on the road with confidence.
