When I change up into 5th gear (manual gearbox) around 50mph, there is a distinct high pitch whining noise. None of the other gears make the same noise, only 5th gear, and it seems to disappear around 60mph.
Is this normal? Anyone else noticed this? My 2000 has always done this since new, and I was just wondering if a) it is normal, and b) does anyone know why it does this?
Thanks,
Kev
