ATS 601-920-4416 A50 TO T87 TRANSMISSION CONTROL MODULE UPGRADE FOR 15 GM 2500HD/3500HD 2WD WITH 6.6L DURAMAX

The ATS 601-920-4416 A50 to T87 Transmission Control Module (TCM) Upgrade is the ultimate solution for owners of 2011 to early 2015 GM 6.6L Duramax trucks facing TCM issues. The A50 and T14 TCMs controlling the Allison 6-speed automatic transmission are known to be prone to wire contact issues, leading to failures and costly repairs. With Allison discontinuing support for these models, ATS stepped in with a revolutionary upgrade to keep Duramax trucks on the road performing at their best.

The new T87 upgraded TCM module from ATS offers a significant improvement in power, performance, and reliability compared to the factory A50 and T14 TCMs. Equipped with Translator® technology and Co-Pilot transmission functions, this upgrade optimizes power holding capability, enabling smoother shifting and enhanced performance under heavy loads. The T87 Conversion also enhances the factory exhaust brake, providing aggressive engine braking and improved safety when hauling heavy loads.

The ATS T87 Conversion is a direct replacement with no permanent modifications required, offering plug-and-play installation with OEM quality components. The T87 TCM features a faster processor for better shift quality and faster response, while the Translator module enhances throttle response, fuel economy, and overall drivability. With updated shift points, improved torque converter lock-up response, and increased transmission life expectancy, this upgrade ensures a superior driving experience while maximizing the potential of your Duramax truck.

Say goodbye to costly dealership repairs and outdated TCM technology. The ATS T87 TCM Upgrade includes a brand new TCM with custom calibration, Translator module for enhanced performance, digital speed and turbine sensors, mounting bracket, and wiring harness. Don’t settle for temporary fixes – choose the ATS upgrade for long-lasting reliability and performance improvement in your GM Duramax truck.
