also try it at a stand still. put on the parking brake, put in neutral and bring it up to the rattling rpm for a few seconds. have someone else look in the engine bay, lay on the ground, etc and try to help pinpoint where the rattle(s) eminate from.

Thanks for the tip.. I'll try that out..
I did some further testing and it seems like the noise is only in automatic and still increasing in speed (from 0-60). I popped it in neutral and everything sounds normal. I tried the paddle shifting and I didnt notice the same noises. I just noticed it while I was in automatic. My guess is the noise might be normal considering its a 2.5 litre V6 engine and the mechanic at the dealership that drove said it was normal as well. I got the warranty.. so only time will tell.
Thanks for all the advice :D
