Hi, everyone! I have a 2010 Mustang GT premium automatic, and I've noticed a slight whine in the transmission as the car accelerates. When it reaches a certain point, the whine stops. The dealership says they contacted a Ford engineer, who said this is the normal operating noise of this model of the Mustang. Has anyone else experienced this? My car has a little over 11,000 miles. The dealership has replaced the car's drive shaft because they said something was wrong with it, and although the transmission whine is much better, it's still present.
