Vehicle is a Impreza WRX. Noise sounds like a very noticeable rattling when clutch pedal is not pressed, when I floor the pedal the noise goes away. In the last week I replaced the entire clutch, flywheel, release bearing, and fluid but the noise is still present. Noise speeds up in low gears and I can’t tell if I actually hear it in higher gears on the highway for example due to engine/ exhaust background noise, is heard in neutral when car is parked and while moving. No gear slippage or noticeable vibration.

Hi,

This could be your input or main shaft bearing it will be most noticeable when the clutch is disengaged motor running because the main shaft is always turning with motor running. the transmission fluid should be checked right away and inspected for metallic shavings (Note: if you have metal shavings or pieces it may need overhauled or replaced). I will attach the video, context and illustrations for you on how to check and change the fluid. Let us know if you need more information and what the vehicle.
