I have a 06 MY 4.4 V8 and just recently I have noticed a hollow blowing noise at 2250 RPM. I have tried setting this RPM with the car in neutral and the noise isn't there. It only appears with the car in D, S or manual and when the engine is under load at a mid throttle position.

I know a V8 does have a throaty noise to it but this noise seems louder and hollow, almost like it echos around the cabin. This is accompanied by a slight vibration through the side of the driver footwell and foot rest. It only appears at 2250 RPM and disappears when the engine either accelerates or decelerates past this figure.

The car has now covered 130k and is due to have the transmission fluid changed at 150k. Has anybody else got any experience of this and if so what did you do to remedy it.

Cheers
