Built For Load Stability And Long Haul Confidence

The ATS 309-824-4248 Stage 2 Crate Transmission Package is engineered to upgrade the performance and durability of your 2001–2002 GM 2500HD or 3500HD 4WD truck equipped with the 6.6L Duramax LB7. At the core of this system is the proven Allison LCT1000 transmission, rebuilt and enhanced by ATS with stronger internal components to handle elevated torque and towing demands. It comes paired with ATS’s Five Star torque converter, offering enhanced lock-up performance, reduced slippage, and better low-speed torque transfer. The included deep transmission pan increases fluid volume and enhances heat dissipation, which is especially important under constant load or hot running conditions. Supporting it all is the Co-Pilot transmission controller, which manages line pressure and shift strategies to improve overall drivability without requiring any custom tuning or calibration. This package arrives fully assembled and ready to install, saving time and simplifying the upgrade process. Whether your truck is used for towing, off-road trips, or heavy work, this setup provides the control, cooling, and capability you need for long-term reliability.
