Give Your LB7 The Guts To Go The Distance

If your 2001 or 2002 Duramax LB7 2WD is still running strong but your transmission can’t keep up, now’s the time to upgrade.

This setup includes ATS’s performance-built LCT1000 transmission, designed to handle the added stress of hard use and heavy loads. The Five Star torque converter delivers stronger lock-up and better torque transfer so you feel more response and less slippage, especially under load. With the deep transmission pan, you get added fluid capacity and better cooling, which really matters when you're pushing your truck. And the included ATS Co-Pilot controller fine-tunes your shifts, giving you smoother gear changes without needing any tuning or custom programming. Everything is pre-assembled and ready to drop in, making it one of the cleanest and most effective upgrades you can make to your Duramax.

Engineered For Real World Towing Control And Cooling Performance

The ATS 309-822-4248 Stage 2 Crate Transmission Package is specifically designed for 2001–2002 Silverado and Sierra 2500HD and 3500HD 2WD trucks equipped with the 6.6L Duramax LB7. At its core is the Allison LCT1000 transmission, which has been completely rebuilt with upgraded clutch packs, hardened components, and recalibrated valve body tuning to improve strength, shift quality, and durability. The ATS Five Star torque converter improves drivability by maximizing torque multiplication and delivering a consistent lock-up during high-load acceleration or towing. For added thermal control, the deep transmission pan increases fluid capacity, reducing the risk of overheating during long hauls or stop-and-go driving. The included Co-Pilot controller works seamlessly with your truck’s stock setup, adjusting line pressure and shift timing for smoother transitions and greater load-handling precision without requiring tuning or software updates. Everything comes fully assembled, ready to install with no guesswork. This package is built for diesel owners who want their truck to do more than just survive the workload, it’s for those who want it to thrive. Whether you're working it hard or daily driving it with pride, this transmission setup is built to back you up.
