Take Your LBZ’s Drivetrain to the Next Level

When your 2006-2007 Duramax is called on to handle serious towing, worksite demands, or performance upgrades, the factory transmission can become a limiting factor. The ATS 309-835-4308 Stage 3 Allison LCT1000 Crate Transmission Package is engineered to meet those challenges head-on. Designed for 4WD trucks equipped with a PTO, this complete package offers everything you need to boost durability, shifting performance, and drivetrain reliability. With ATS’s Five Star Torque Converter included, you’ll notice improved power delivery and responsiveness right out of the box, whether you’re hauling heavy loads or pushing your truck’s performance on the open road.

Built Strong for Daily Work or Weekend Fun

ATS doesn’t stop with just a converter. This package also includes their deep transmission pan to boost fluid capacity and cooling, helping extend the life of your transmission under demanding conditions. The Co-Pilot Transmission Controller enhances shift timing and line pressure management, giving you smoother and more consistent performance, even when towing or running higher power levels. A billet input shaft rounds out the package, addressing one of the Allison’s known weak points and giving you the confidence to put your truck to work without holding back. Please note that a $500 shipping surcharge applies at checkout, but the peace of mind this package delivers is worth every penny.
