2019 - 2024 Ram 6.7L Cummins 68RFE | Transmission Tuning by PPEI

Smooths out the rough shifting 68RFE

Shifts so much smoother. Much nicer to drive.

Alot better that factory tune!!

Just installed the transmission tune on my 2021 Ram 2500 with the 68RFE transmission and the difference is unreal!! Finally this thing shifts like it should have from the factory. It doesn't hunt in-between gears like it used to and the torque converter locks up alot faster. It also stays in gear longer when pulling a steep hill or heavier loads so you can use the low end power that the Cummins provides. Installation is pretty straight forward with the exception of having to hack into your factory OBD2 plug to install the can plug that's provided. If you don't want to do that, you can order a plug in harness for Kaodtech for $55.00 like I did. Overall, I'm very pleased with this tune!!
