Built With Billet Strength And Intelligent Engineering

The ATS Stage 5 Allison LCT1000 Transmission Package offers a full spectrum of performance upgrades tailored to withstand the demands of tuned or heavily worked diesel trucks. It includes a billet input shaft and billet intermediate shaft to prevent torsional failure, as well as a billet P2 carrier and billet C2 hub paired with a modified P1 sun gear for superior geartrain integrity. The deep pan boosts fluid capacity for better cooling and longer service intervals, even under intense conditions. The included ATS Co-Pilot transmission controller helps optimize shift points and manages line pressure to protect clutch packs from premature wear. This system is fine-tuned for 2WD applications with PTO-equipped LML Duramax trucks from 2011 to 2016. With all components working in sync, the transmission ensures smoother shifts, better towing response, and improved durability over stock. It’s a purpose-built system designed to handle more horsepower and last significantly longer than factory setups.
