I drove a gt with 5 miles on it while i was there and it had no whine. They told me i didn't drive it properly. Whatever that means. I took it to a different dealership and they said same thing normal gear whine from the mesh in the gears. Funny how gears 1 thru 4 do it but not 5 and 6. I am scared to do intake exhaust now but can't get anything out of Ford.
