What benefits come from 68RFE Tuning?

The 68RFE transmission provides some improvements over previous automatic transmissions matched with Cummins pickup trucks. With 6 gears equipped to help with fuel mileage the new(er) transmission has some other improvements. When these transmissions rolled out in 2007.5, they were the first diesel specific transmission developed by Chrysler. Finally they had stepped up the filtration and moved away from bands being used internally. All in an effort to extend service intervals, increase reliability, and drive down maintenance cost. The dual face torque converter clutch and integrated tow haul capability made the 68RFE a truly solid option for diesel truck owners.
