2013 Chrysler 300S NAG 1 transmission whine
 

I recently purchased a 300S 5.7 Hemi with 30,000 miles on it. 5speed transmission. When I first test drove it I noticed that in 2nd gear it made a sound just like a turbo whistle that increased in pitch with engine RPMs .Only in 2nd gear, stops when it hits 3rd. I mentioned it to the dealer and he told me yes they all do that.

I talked about this to another other technician and he told me that it sounds like the planetary gear was about to go. Took it back to the dealer and test drove it with a technician. He said yeah somethings wrong. Now it been at the dealer for a week now waiting for Chrysler Corporate to tell them what to do next Still under limited warranty.
Many other NAG 1 5 speed owners experience this turbo sound in a certain gear? It only does this In 2nd gear. Thanks
