Unlock Power Without Sacrificing Street Driveability

If you’re looking to get more from your 8.1L-powered GM truck without turning it into a full-on race rig, the ATS Stage 2 LCT1000 Transmission Package is the perfect middle ground. Built for daily drivers and weekend warriors alike, this kit transforms your stock setup into something you can count on for towing, performance, and long hauls. Whether you're pulling a camper to the mountains or hauling gear to the jobsite, you’ll feel the difference in shift quality and torque handling right away. The included TripleLok Torque Converter helps transfer power efficiently, while the CoPilot controller makes sure shifting stays tight and responsive no matter the terrain. It's a game-changer for anyone who’s ever felt their stock transmission struggle under load. Plus, the added depth of the transmission pan not only helps with fluid capacity but also keeps temps in check on longer runs. This is the kind of upgrade you’ll wonder how you ever lived without.

Built To Take The Heat Of Heavy Load Demands

The technical foundation of this transmission package is engineered around durability and precision. At the heart of the upgrade is the ATS-built Allison LCT1000, customized to outperform OE specs in both pressure and clutch engagement. The TripleLok Torque Converter ensures torque multiplication under high load conditions, preventing slippage and improving power delivery through every gear. The deep transmission pan plays a vital role in maintaining optimal fluid temperatures and extending service life, especially under heavy towing or extended driving. The included CoPilot controller gives the system intelligent feedback by adjusting transmission pressure and torque converter clutch lockup based on boost, speed, and throttle position. This means your transmission is always working at its most efficient and protective settings. If you're planning on pushing your 8.1L setup harder than stock, this Stage 2 package offers the kind of engineering you need to do it confidently and consistently.
