When at a standing idle or in park, I've begun to hear a sound like aluminum sheets vibrating against each other coming from underneath (most noticeable when in garage). Noise is not present all the time. If I depress the brake and then release quickly while in park, the vibration becomes louder for a brief moment. Checked trans fluid - OK. Have checked for loose hanger on exhaust. No problem there. Thoughts?
