ATS Diesel 11-14 GM 6.6L Duramax 2WD TCM Upgrade A50 to T87

This kit includes the ATS Diesel TCM (Transmission Control Module) upgrade, designed to replace the factory A50 module with the more advanced T87 module for your 2011-2014 GM truck equipped with the 6.6L Duramax diesel engine and 2WD. This upgrade is for trucks originally equipped with the A50 TCM, allowing you to benefit from the improved capabilities of the T87 system. It's a significant step up for those looking to enhance their truck's transmission performance and control.

The T87 TCM offers more processing power and updated logic compared to the older A50 module. This translates into smoother shifting, better torque management, and improved overall transmission responsiveness. The kit is well-built and intended as a direct replacement for the factory module, simplifying the installation process. While it's a substantial upgrade, it's designed to integrate with your existing transmission hardware, meaning no major mechanical modifications are typically required beyond the module swap and necessary programming.

When installing this TCM, it's important to follow the manufacturer's specific programming instructions to ensure it communicates correctly with your vehicle's other electronic systems. This upgrade is a popular choice for Duramax owners who tow or haul frequently, as the improved transmission control can lead to a more stable and efficient driving experience under load. Ensure your vehicle's VIN is correctly registered during the programming phase to unlock the full potential of this advanced transmission controller.
