Ok I have only had my 06 coupe about 3 weeks and havn't driven it much , but upon driving it yesterday I noticed a slight transmission whine on the highway, which changed pitch with gears, was slightly less in 5th and disappeared with clutch pushed in. Is a slight whine normal or should I be worried, the car only has 4,000 miles so I dont know, couldnt have been abused that hard. any help guys?
