the noise happens when i put the car in 1st and let the clutch out. at around 1200 rpm there is this grinding coming from the tranny until about 1400 rpm. then it does it again when the clutch is out in 2nd. even if i'm in second and slow down to around 900-1000 rpm it will make the grinding noise till about 1300 rpm. really wierd, and it only happens in 1st and 2nd. anyone have any ideas?
