Perhaps since this is a rather new, (To you), vehicle, the fluid itself may be all it is. There is another Transmission thread floating around recently about the pitfalls of any fluid other than ATF+4 for the Chrysler 42LE transmission.
Myself, I would probably hire the services of a tech with the machine to flush the system and replace the fluid with genuine ATF+4. Then drive it and see how it does.
The only other option I could venture would be to have the trans controller scanned for faults and CVI values. CVI refers to the amount of time the trans takes to completely fill each piston area for a given operation or shift. The clutch volume index is helpful to properly diagnosing a transmission concern.
