Interesting occurance, keep us posted.

Different vehicle and different trans but the same thing happens on my '12 Grand Caravan, although sounds like to a much lesser degree than what you've experienced. The tranny bangs when it downshifts into 3rd or 2nd usually when coming to a rolling stop coming off the freeway or in stop and go traffic.

Recall has been issued for a transmission software update for the minivans. I'm taking it in this weekend.

Sorry for the initial bad luck. Knowing the fault codes would help us know what area of the transmission failed. Chrysler will want the unit back for failure analysis.
I don't think that the dealer's will do anything as involved as an overhaul on the ZF gearbox.
