Hello, I drive a stick shift 2015 Scion tC, and have noticed a noise coming from the engine bay. I am convinced it's coming from the drive train, specifically the clutch/transmission. The noise presents itself when the clutch is released, in neutral or in gear. It gets louder when in low gear when I first take off, but is not as noticeable in when cruising in high gear. It gets louder the higher the rpm in gear. It is like a whirring, or rasping kind of noise. It goes away completely when the clutch is pushed in. I haven't noticed any driveability issues so far. Some people that have heard it in person think it's the release bearing, but I think it's an input shaft bearing. I have an appointment to get it checked out but I wanna see what guys on here think. Thanks

 

Input shaft bearing needs to be replaced. Super common on the 2g's. Not cheap to fix though (basically replace the trans). Check the forums for info on it.
