My family?s ranch has a 07 and 08 3500 cab and chassis with the aisin trans behind a 6.7 with a smarty programmer. Engines run great but between 50% and 90% throttle the trans will shift wierd. If you go 100% throttle it shifts fine. I have zero experience with Mopar systems. I have not even plugged my hptuners into them. Was curious if there is trans Tunning that can be done. It would be for towing
