2007 - 2009 Dodge 6.7L Cummins 68RFE | Transmission Tuning by PPEI

08 3500 ram

Trans tuning isn’t the best. Has 225psi like stated, but lockup is funky unlocks at high rpm for no reason, won’t stay locked at low rpm and when you let off throttle at low rpm it’ll lock and jar the whole truck when in 3rd and 4th. They need to fine tune their tuning for sure. Cct was way better back in 2014 but unfortunately can’t get it now

Awesome guys to work with

Great customer service, had issues loading trans tunes Sunday morning and was able to get Logan Forbes on the phone and he walked me through my situation. Tunes are great feels like a totally different truck.

Much improved

Have not towed with the truck since updating but truck shifts are more crisp and they take place at a more reasonable rpm given the power curve of the truck. So far very happy with the tune.
