2010 - 2021 | Dodge Ram | 6.7L Cummins & 68RFE Transmission ONLY |
If you're using Proven Diesel Tuning, getting TCM tuning for your 68RFE is a smart move. It boosts your truck's line pressure, making towing a breeze!
TCM tuning offers multiple benefits. It makes your transmission shift more firmly and hold gears longer when towing. This reduces transmission temperatures in your 68RFE. You can order it for either EFI - Live or EZ - Lynk Systems!
Features

Notes
- You must own an EZ LYNK AutoAgent and link your vehicle with Proven Diesel. An AutoAgent is needed to program your vehicle. If you don't have one, go to your vehicle’s tuning options to buy the complete package.
