The jeep has the newest tune.
... but does the Trinity tuner have the latest firmware version?
There have been some problems that were not the fault of the tune itself, but the tuner's software that writes the tune. If you contact RIPP with the Trinity in-hand and powered up, they should be able to walk you through checking the firmware version on your tuner and let you know if you need to update it. They should be aware of which versions of the firmware had problems.
So is this solved?
I followed the above steps before. Then I had the ecu reflashed at the dealer and reinstalled the tune. They were afraid the aev procal was stacked.
As of now, we still feel the AEV does a better job of writing to the ECU/BCM than the intune in the 2012+ for wheel/tire and diff ratios. Diablosport is always updating their firmware. Though we know this to be a sure fire solution for customers that may be experiencing transmission shift issues. This affects only a few CAL ID vehicles.

My dad's has the trinity vs the intune and was advised to use the aev procal and not the diablo when we went to new gears and tires.
