Technical Gearbox Noise

[Dionisis13]

Hello fellow Stilo drivers,
I have a problem with the 6speed manual gearbox in my Fiat Stilo 1.4 95Hp 2004. I shift in 5th or 6th gear and when I leave the clutch and press the gas pedal there is a knocking sound which comes from the gearbox. The car is at the mechanic shop but the mechanic told that the valvolines in the gearbox where black and he needed to dismantle the gearbox to open it further inside to find the problem. Maybe I will have some answers tomorrow. Has this ever happened to anyone? If someone has a hint please leave a reply. I don't know how much it may cost to fix it.
Thanks

Sounds like damaged bearing. Easy fix.
It happened to me, I fixed it like this:
