2011-2016 Duramax Proven Diesel TCM Tune File

Fits

This is for guys who are currently running Proven Diesel Tuning and have made the wise decision to get some transmission tuning to help boost the line pressure in your truck.

Adding TCM tuning will make your transmission shift firmer and hold gears longer while towing which in turn will help reduce transmission temps in your LML. This can be ordered for either EFI-Live or EZ-Lynk Systems!

• Boosts Line Pressure in Transmission
• Holds Gears Longer While Towing
• Reduces Transmission Temperatures
• Shifts Firmer

• An EZ LYNK AutoAgent must already be owned and your vehicle must be linked with Proven Diesel. An AutoAgent is required to program your vehicle. If you do not own an AutoAgent, please navigate to your vehicle’s tuning options to purchase the complete package.
