Hi guys, Just took my car in and upgraded to a heavy duty clutch. After getting the car back, when I turn the car on it always makes the noise as if you were to turn the car over if it were already on. That grind noise. Even if I time it perfectly, it still makes the noise. Has anyone ever had this problem? Just gives me some idea what to tell the mechanic. Fg 2008 xr6t.
