2013 - 2018 Ram 6.7L Cummins 68RFE | Transmission Tuning by PPEI



Extend your transmission life and increase your fuel economy with PPEI Transmission tuning! A MUST for tuned trucks with additional torque.

The refined shift points get rid of the low rpm “Lazy” feel these trucks have that force the driver to stab the throttle for a downshift – not cool and a fuel economy killer! For vehicles with larger turbochargers, ppei transmission tuning is a must to get the engine back into a rpm range to match the torque curve of the new turbo.

Along with the improved shift points, PPEI also refines the torque converter lockup strategy to put the power to the ground much more efficiently for improved fuel economy by eliminated unnecessary slip in the torque converter – which also drives down heat in typical “unlocked” conditions.

We at PPEI take pride in our work and if there is anything you wish to have changed in your transmission calibration,  we are here to make it fit your driving style - "Custom Fit"!

Disclaimer for PPEI Transmission Tuning on 2013 - 2018 Ram 6.7L Cummins 68RFE

Please be aware that the PPEI Transmission Tuning for the 2013 - 2018 Ram 6.7L Cummins 68RFE is a complete flash process. When you install this transmission calibration, a stock engine calibration will also be installed unless a PPEI engine tuning is already in place. Consequently, if you currently have engine tuning from another company, installing this PPEI Transmission Calibration will overwrite any existing engine tuning with a stock engine calibration.

It is critical to note that this process is irreversible with non-PPEI calibrations. If you choose to install a different engine calibration after you have installed the PPEi Transmission Calibration, it will also overwrite the PPEI Transmission Calibration.

Users are advised to consider these factors carefully when using PPEI tuning products to ensure compatibility and avoid conflicts with other tuning modifications. This disclaimer serves to inform you of the integral changes that will occur to your vehicle’s calibrations upon installation of PPEI products.

This can be installed with the EFILIVE & EZLYNK.

Best tuner ever

David Dunn
2017 Ram 100HP and Trans Tune

Extremely happy with the tune and customer service. Initially I had an issue getting the tune to download, the guys at PPEI walked me through a couple of procedures to get it working. The truck has much more power, but what I really noticed was transmission shifts. No more hunting for gears, a much smoother overall experience. I also had a 2-mpg gain while towing our camper. Couldn't be happier.

Rob McMinn
Ram 2500 60hp and trans tune

I purchased the 60hp power and transmission tune for my 2016 Ram 2500 Diesel. I like the power increase for towing however changes in transmission characteristics seem minor but improved. I would've appreciated a little more info on tuning parameters because my original intent was just to increase transmission line pressure to help longevity. But as mentioned above, power increase is noticeable transmission characteristics are not. Also it would've been nice to have some written instructions or a link on how to load the tune onto my truck which I thought was a bit ridiculous considering paying $1500 + for the product. Had to search around for a video that wasn't exactly what I had. Still seems like a good product and my Ram has 45k on it so we'll see how the Transmission holds up.
