ATS Diesel 2011-2014 GM 6.6L Duramax TCM Upgrade A50 to T87

The ATS Diesel TCM Upgrade module is built around a robust, fully sealed electronic control unit that replaces the factory A50 transmission control module with the more advanced T87 unit. This upgrade is specifically designed for 2011-2014 GM trucks equipped with the 6.6L Duramax diesel engine, addressing the limitations of the original transmission control system. By integrating the T87 module, you gain access to improved shift logic and better overall transmission performance, which is crucial for managing the power output of these heavy-duty trucks.

This unit is not just a simple swap; it's a comprehensive solution that brings modern transmission control technology to your Duramax. The T87 module allows for more precise control over line pressure, torque converter lock-up, and shift timing, leading to a smoother driving experience and potentially improved fuel efficiency. The sealed enclosure ensures that the electronics are protected from the harsh under-hood environment, including moisture and dust, which contributes to its long-term reliability. This upgrade is particularly beneficial if you've modified your engine or are experiencing less-than-ideal shifting behavior with the stock setup.

When installing this TCM upgrade, it's important to follow the manufacturer's instructions carefully, as proper integration is key to unlocking its full potential. This module is designed to work seamlessly with your existing transmission hardware, but it's always a good idea to ensure your transmission fluid is fresh and at the correct level before installation. The difference in shift feel and responsiveness can be quite notable, making this a worthwhile investment for owners looking to get the most out of their Duramax truck.
