im posting on behalf of a friend ive taken his post from a fiat forum here it is
Right, the car has started grinding when I'm holding the bite point and moving slowly, also when I'm going fast and putting my foot down.
My dad seems to think it could be the gear box, as I have to re sit the clutch sometimes to stick it in reverse, but the gears aren't stiff as such.
He said either that, dodgy clutch fitting or the driveshaft.
But yeah, the noise is grinding, not constant grinding, sounds like it's slipping, but it isn't (I did the 4th gear on a hill test etc and it doesn't slip one bit)
Thanks again for all the help.
