If you rely on your LLY Duramax to tow, haul, or handle long days on the road, you know the factory Allison can only take so much before it starts slipping or failing under pressure. The ATS 309-833-4290 Stage 3 Allison LCT1000 Crate Transmission gives you a complete, ready-to-install package designed to handle serious demands. Built specifically for 2WD, PTO-equipped models, this package features ATS’s performance-enhanced transmission along with their Five Star torque converter. Together, they improve torque transfer and help your truck put power to the ground where it belongs. It also comes with a deep transmission pan that increases fluid capacity, helping to lower operating temperatures when your truck is working its hardest.
