I too have a definite buzzing coming from what I think is the transmission heatshield and it only does it when the car's stationary, in Drive & held on the brake. I think it's been mentioned somewhere here before.
never thought of that. that's a good point. I think I've just recently noticed that if there is a noise when I'm parked and idling, if I hit the gas and increase the revs then after the rev's come down the noise seems to go away. thanks.
