The ATS Diesel Model 6019204368 offers a revolutionary upgrade for your 11-14 GM 6.6L Duramax 2WD truck. This TCM Upgrade is designed to replace the vulnerable A50 Chevy TCM, which is the weak link of the Allison 6-speed automatic transmission. By seamlessly transitioning to the T87a TCM, you can experience improved performance, increased durability, and enhanced safety features. This upgrade is the perfect solution for Duramax owners looking to overcome the limitations of the A50 TCM and enjoy a more reliable driving experience.

Key Product Properties and Specifications

The ATS T87 Conversion comes with a custom ATS calibration pre-installed, ensuring optimal performance for the Allison transmission. This upgrade offers a direct replacement for the factory A50/T14 TCM, with no permanent modifications required. The T87a TCM features a much faster processor than the A50, leading to better shift quality, faster shifting, and overall improved drivability. The included Translator® module enhances the transmission pressure function, allowing the factory Allison transmission to handle higher power levels and increased durability. This package includes a brand new, factory-sealed Duramax TCM, complete wiring harnesses with state-of-the-art technology, and a mounting bracket for easy installation.

Practical Uses and Benefits

This ATS Diesel TCM Upgrade is perfect for both stock and modified trucks, providing enhanced performance and increased throttle response. The improved shift points and torque converter lock-up response help maintain the engine within the desired RPM range, maximizing fuel economy and MPG improvement. This upgrade not only increases the life expectancy of the Allison LCT1000 Transmission but also offers superior engine braking reduction with heavy loads, making it ideal for drivers who frequently haul heavy loads. By choosing this upgrade, you can expect a safer driving experience, reduced maintenance costs, and a significant increase in the value and longevity of your vehicle. Upgrade your Duramax truck today and experience the difference that ATS Diesel can make!
