I have an '03 NSX with 60k miles. I noticed this a few weeks ago, and don't recall if it's always been there or if it's new. I have a light ticking/clicking sound coming from the transmission area while coasting- higher rpms, removed targa, and/or stereo all mask the noise, but found out after driving casually with the radio off. As soon as any throttle is applied, the sound goes away. The sound occurs while in gear and in neutral, is speed dependent, and occurs multiple times (3-4?) per revolution (found out under the car- spin the wheels hard and can hear it faintly). The only thing I've done is a transmission fluid change with Redline MTL filled to proper levels. I've gone under the car and checked for any boot issues, grease leaks, etc., as well as axle nuts. Everything looks fine- noticed sound after a safety inspection at a performance shop where it passed with no issues (that's why the stereo was off).
Any suggestions? Is this normal?
