Hello,

does somebody experienced or knows what an "cutting wood with a circular saw" ONLY in second gear and ONLY at a certain rpm could cause it? Didnt find any info about this anywhere.

This only happens when the transmission/engine is at operating temperature (fully cold this doesnt happen). And only in second gear at EXACT 2600rpm.
If i accelerate slowly past that rpm the noise is quieter than when accelerating little bit faster trough.

Holding the rpm steady at that range results in no noise.
Revving the engine in neutral - no noise,
Revving with clutch in and in second gear - no noise
No modification to the drivetrain.
No unusual problems with the gearbox, shifts smooth (cold and warm)
Noise comes from the front/middle of the car
Only hear it audible enough with windows down

Could be the TOB? Squeaky and crunchy feel when pressing the clutch pedal. Car has about 35k miles on it.

I know, without any "soundfile" or "video" it will be hard to diagnose this. But the "cutting wood with a circular saw" nails it. And there's no point in recording it, my mic would rather pick up the exhaust.
