2500 and 3500 HD Silverado/Sierra's equipped with the 6.6L Duramax routinely have factory TCM issues that cause limp mode, loss of PRNDL display, and trigger check engine lights. The DuramaxTuner Pre-Tuned Replacement TCM is a brand new and upgraded TCM for your stock late 2015 and 2016 Allison 1000 T87 Transmission Control Module.  Your new TCM will arrive pre-programmed for your VIN and includes our custom TCM Tuning. 

Why do you need TCM Tuning?

  • Required for the best possible drive-ability
  • TCM Tuning is the best tool to ensure your engine is operating within its preferred rev range

Benefits of TCM tuning over stock include: 

  • Raised mainline pressure for improved clutch holding capacity and improved transmission life (a DuramaxTuner Exclusive feature)
  • Refined shift schedule to take advantage of the wide Duramax Torque curve
  • Improved torque converter clutch engagement settings to allow lockup under heavy loads, planting the power to the ground and lower trans temps
  • Torque limitations adjusted to allow high RPM fueling in performance applications
  • 2nd gear start in 4wd low range (can tap down to first)
  • Further adjustments are available for customers with larger than stock turbochargers or significantly oversized tires 

TCM Tuning is especially important for trucks with:

  • Larger tires (35”+)
  • Modified turbo(s)
  • Built transmission
  • Any modification that impacts operating RPMs

Towing

  • Keep your truck in its power band when lugging up a grade

Performance

  • Optional 2nd or 3rd Gear Start for competition applications
  • Optimize your aftermarket turbocharger performance
