I just had new syncros put in my 02 WRX about 6 months ago. I have never dumped the clutch or beat on it like that but I notice this noise coming from my trans when it is only in neutral. It is strange though because the noise goes away when you depress the clutch and as soon as you let the clutch up you can hear some kind of bearing spinning. The car only has 36,000 on it and the clutch has like 12,000 on it. Any suggestions?
