2017 Mazda 3 GT with A/T. My transmission whines noticeably when it's cold (pretty loud actually).....anyone else notice this? The car runs and drives perfectly. Just a little annoying. 5,000 miles as of today and I bought it new in July of this year.

IF it's a whine, probably a factory defect on the driveline. This would be a take it into the dealer item.

If it's whining due to holding low gear longer when it's cold for a few minutes it could be the drive system controls warming up the exhaust cats to reduce start up emissions.
