Built for Duramax Owners Who Expect More from Their Truck

This complete package includes ATS’s upgraded LCT1000 transmission, designed to handle higher torque and deliver smoother shifts.

These components provide the extra strength needed to prevent failures that are common in high-power applications. Designed as a direct bolt-in replacement, this package makes upgrading your drivetrain simple, with no custom fabrication or major modifications required. Whether you use your truck for work or weekend performance, this transmission is built to keep up with the demands of real-world driving.
