DIESELR MPVi4 68RFE Transmission Tune File (2022-2024 Cummins 6.7L - 68RFE)

The Dieselr MPVI4 68RFE Transmission Tune File for 2022–2024 6.7L Cummins is a platform-specific calibration developed for trucks running our paired ECM tuning. This file is delivered for HP Tuners MPVI4 and is engineered to improve shift strategy, clutch control, torque management, and drivability under real load conditions.

This TCM calibration is only compatible with Dieselr ECM tuning. Purchase confirms you are currently running, or will be running, our matching ECM file.

Unlocked Aftermarket ECM Requirement (Reccomended)

2022–2024 Cummins platforms require an unlocked ECM solution before tuning can be performed. This product does not include an ECM.

If needed, you may add a Mopar 2019–2021 6.7L Cummins ECM swap. Professional installation is strongly recommended. Dealers equipped with OEM tools can manage PCM swaps and restore factory calibrations if required.

Calibration Strategy

• Refined shift timing and pressure mapping
• Torque management recalibration matched to Dieselr ECM tuning
• Improved clutch apply consistency under load
• Validated drivability across tow and daily-use scenarios

Shift-On-The-Fly (SOTF) support is available for most applicable setups. In rare cases where SOTF proves incompatible, a single fixed calibration will be supplied. SOTF service is non-refundable once development begins.
