Hi and thanks for your help. The car shifts very hard, brake applied when shifting in/out of P, R, D. The gear indicator does show which gear it is in inside the square, I have tried clearing the PO2310 code controller network communication w traction system failure by using my Mac Mentor but it states it needs to be key on, engine off even if that is how I am trying to clear it. I have also tried clearing it w the engine running, and even disconnection the battery for 1 minute. It always come back to the same lights and code. There was trans fluid inside the conductor plate exterior connection and so I did rinse all parts down well with brake cleaner. WHen I have gotten a similar code from other brand vehicles, especially with the traction and brake light on, it seems like it comes down to a BCM unit malfunctioning. But I am new to Chrysler electronics and am here to learn from those who know the system. Any suggestions are appreciated.
