ATS 2006-2007 6.6L LLY / LBZ / LMM Duramax Stage 1 Allison LCT1000 Transmission Package 4WD w/ PTO

This ATS Diesel Stage 1 Allison LCT1000 transmission package is built with a proprietary triple-disc torque converter, featuring a billet cover for added strength. It's designed for 2006-2007 Chevrolet and GMC trucks equipped with the 6.6L Duramax LLY, LBZ, or LMM engines and the 4WD Allison transmission with a Power Take-Off (PTO) provision. If you're looking to handle more power than the stock transmission can manage, this package offers a solid upgrade path.

The Stage 1 build includes updated clutch packs and improved valve body calibration. These changes help the transmission shift more firmly and efficiently, which is crucial when towing or hauling heavier loads. The triple-disc torque converter is a key component, providing more surface area for clutch engagement, leading to better power transfer and reduced slippage under stress. The billet cover on the torque converter adds significant durability, preventing failure points common in stock units when subjected to higher torque loads. This package is a comprehensive solution for owners who need a transmission that can keep up with their truck's capabilities.

This package is a complete transmission assembly, ready for installation. It is specifically configured for 4-wheel drive applications and includes the PTO provision, making it suitable for a wide range of heavy-duty uses. Ensure you consult the manufacturer's installation guide for specific details regarding fluid requirements and any necessary supporting modifications for your particular truck.
