2011-2016 Duramax - Proven Diesel TCM Tune File

Fits

This is for guys that 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!
