G'day guys. Since I had a heavy duty single plate put in I've had a loud rattle gearbox rollover noise. It's been a couple of years now and it's still about the same, maybe slightly worse. Has anyone been successful in fixing the rattle without rebuilding or replacing the box? Basically the rattle is quite loud when accelerating in 1st,2nd,3rd from about 2k - 3k rpm then it stops. There is a whirring and and slight rattle when in neutral at Idle and it stops once the clutch is pressed in. Any feedback, tips, help ect would be greatly appreciated! Cheers
