Give Your Duramax The Transmission It Deserves
If your LBZ-powered 2WD truck is putting down serious power, the stock transmission can only take you so far. The ATS Stage 4 Allison LCT1000 Crate Transmission is built to transform your drivetrain into a powerhouse of durability and control. Designed specifically for 2006–2007 Silverado and Sierra 2500HD or 3500HD models with PTO, this package gives you everything needed to hold up under high torque and aggressive driving. It includes the proven ATS Five Star torque converter for smoother launches and stronger torque transfer, along with billet input and intermediate shafts for extreme strength where it matters most. You’ll also get the ATS deep transmission pan for better cooling and added capacity, which is a must for towing or hauling heavy loads. The Co-Pilot transmission controller ensures pressure is right where it needs to be, giving you firmer, more consistent shifts even under strain. Whether you're towing across the country or building for performance, this transmission gives you the peace of mind to put your power to work.
Tuned For Strength Precision And Heavy Duty Operation
The ATS 309-843-4308 Stage 4 Allison LCT1000 Transmission is a comprehensive upgrade engineered for 2WD GM Duramax trucks with PTO from model years 2006 to 2007. Built to exceed factory limitations, this package features billet input and intermediate shafts to handle higher torque loads and resist twisting under stress. The included Five Star torque converter improves torque multiplication and drivability by reducing slippage and maximizing efficiency across the RPM range. Also included is the ATS deep transmission pan, designed to increase fluid volume and cooling capability, which helps reduce thermal breakdown under prolonged towing or performance use. The Co-Pilot transmission controller fine-tunes shift pressure and timing, preventing clutch slip and extending the life of internal components. This transmission package is ideal for trucks with significant power upgrades or those that frequently operate under high load conditions. All components are designed to work in unison to deliver improved responsiveness, better durability, and enhanced towing confidence. A $500 shipping surcharge applies due to the weight and specialized freight requirements.
