New Touring V6 6AT. Besides the erratic shifting, engine braking, gear hunting and clicking/thunking noises when changing directions, I have also had clicking/rattling noises when coasting under no/partial throttle. Sounds like gear lash in a manual transmission car. Also get a slight clunk when in sport mode and blipping the throttle, again, like gear lash in a manual. Will be scheduling appointment with dealer service department for inspection soon.
