Could this be a bad throw out bearing?
Just bought my first manual ('20 Corolla Hatch) about 2 months ago and just noticed this whining noise that is RPM dependent and only goes away whenever the clutch pedal is pressed in. It is due for a fluid change and I plan on doing it within the next few days, but internet research suggests that this is a bearing/clutch issue. I know a lot about engines but I know pretty much nothing about transmissions so any and all help is appreciated!
