Rattling Noise

[JDMBuddyClubEP3]

hey guys, just noticed when i have my lights on and im sitting at idle i hear a bit of a rattle, not sure if it is normal...if i hold up the window up buttons it gets louder...popped the hood and had a listen, its comming from tranny side, or tranny itself, any suggestions??

The other issues shouldn't be related unless it's something rattling from engine vibration and the use of electrical devices is causing increased load on the engine.

I have a similar problem with a rattle I believe coming from a heat shield. It comes on a lot when the engine is at idle, but put under a bit of load - A/C most notably.

ya its normally at idle when i hear it, i hear the heatshield at the cat is bad for it, but i'd hear that from under the car
