05 automatic.

Just started doing this.

Problem is I don't know what I should be listening to... Not sure what's the noise you're trying to point out, and what's just the sound of you handling the phone, etc. If you could describe the sound that might help, or have someone else record from under the hood while you rev up?

 

I detected the noise you recorded. Mine is the same year, auto and when it's transmission failed that noise was never present.
Good luck and hope someone can help identifying the sound.
