Bring New Life to Your LB7’s Drivetrain

If your 2003-2004 Duramax is starting to show signs of transmission fatigue or you’re planning a serious performance build, the ATS 309-835-4272 Stage 3 Allison LCT1000 Crate Transmission Package offers the durability and performance you need. Designed specifically for 4WD trucks with a PTO, this package is built to handle towing, daily driving, and performance upgrades with ease. It includes the ATS Five Star Torque Converter, which improves power transfer, reduces slip, and helps your truck feel more responsive whether you're pulling a trailer or running empty. This transmission package gives your LB7 the confidence to handle the power you throw at it without the weak links of a stock setup.

Engineered for Reliable Power and Smooth Operation

ATS packs this transmission with premium components to improve durability and performance across the board. The deep transmission pan increases fluid capacity and improves cooling, helping to keep transmission temperatures under control when you’re working hard. The Co-Pilot Transmission Controller takes control of shift timing and line pressure, giving you smoother shifts and more consistent performance under load. Rounding out the package is a billet input shaft designed to handle the added torque of performance tuning and heavy towing. Whether you’re building for work, play, or both, this transmission package is built to last. Please note that a $500 shipping surcharge applies at checkout.
