    S AWD Abs sensor # 2 dies just replaced with new Mopar part from local dealer now the trans bump shifts when it rains. Fine all other times, don't know about snow yet. Ideas?

    From research it appears that the 5 speed transmission used in the 2015 Chrysler 300 was a continuation of the W5A580 5 speed rear wheel drive transmission (NAG1 unit) borrowed from Mercedes when Daimler owned the company. I would inspect transmission fluid for contamination and interrogate the transmission controller for diagnostic codes.

    Just a minor point - this should be a TF8 trans. The 845RE was std on all retail V6 cars after 2014 - it is Chrysler Kokomo's version of the ZF 8HP45.

    The Kokomo-built A580 (essentially a Chrysler-reengineered Mercedes 722.6, and originally the ZF 5HP30) did continue on in the Charger Pursuit through 2020.
