TRANSMISSION TUNING 2015.5-2016 LML 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
