2019-2021 6.7L Cummins 68RFE Transmission EFI Live TCM Tuning

The 68RFE transmission used in the 2019-2021 Ram 2500 and 3500 equipped with the 6.7L Cummins have a reputation for a sub-optimal performance from the factory leaving quite a bit to be desired if you're working the truck hard or have plans to increase engine performance. Changing the OEM TCM calibration is especially important for towing heavy, performance use, modifying your truck, and/or install ECM Tuning. Custom TCM Tuning gives you quicker shift changes, smoother operation, helps improve fuel economy, can extend the life of your transmission, and provides an overall better driving experience.

Calibrated Power Solutions' Custom TCM tuning will decrease time between shifts and improve clutch holding capacity by increasing line pressure electronically. This will make a more durable, better feeling, and better driving transmission. It can also help keep the engine in the ideal RPM range to utilize all of its potential power. 68RFE transmission tuning can be utilized to enhance performance of both stock and built transmissions.
