ATS 601-940-4416 A50 TO T87 TRANSMISSION CONTROL MODULE UPGRADE (TCM) 2015 GM DURAMAX 6.6L LML

The ATS 601-940-4416 A50 to T87 Transmission Control Module Upgrade (TCM) for the 2015 GM Duramax 6.6L LML is the solution you need for enhancing the performance and reliability of your GM Duramax/Allison Diesel Trucks produced from 2009 to 2017.

The A50 and T14 TCMs that have been traditionally used to control the Allison 6-speed automatic transmission are known to be the weak link due to delicate wiring that can short-out over time. With Allison discontinuing support for these TCMs, over 10,000 Duramax owners were left without a solution. The ATS T87 Upgrade replaces the outdated TCMs with an advanced assembly including the Translator® module, providing a significant boost in power, performance, and reliability.

This upgraded TCM introduces our Translator® technology, enhancing the functionality of the factory transmission by increasing power holding capability and enabling smoother shifting even under high power levels. With the Co-Pilot transmission functions built in, the T87 Upgrade not only prevents clutch pack damage in the Allison transmission but also offers a more aggressive factory exhaust brake over the original TCMs.

This plug-and-play upgrade does not require any permanent modifications and comes with all new components, eliminating the need for a core charge. It works seamlessly with stock or modified trucks, improves throttle response, increases fuel economy, and provides updated shift points for optimized engine performance. The improved torque converter lock-up response and enhanced shift quality make for a more enjoyable driving experience.

Included in the package is a new T87 TCM with custom ATS calibration, a Translator® module, digital speed and turbine sensors, mounting bracket, and wiring harness. With this upgrade, you can expect increased transmission life expectancy, better MPG, and a safer driving experience, making it a must-have for any GM 6.6L Duramax owner looking to enhance their vehicle's performance.
