Real high pitched metallic rattle

[Mahstang]

I bought my 2007 Mustang GT with roughly 31,000 miles and ever since I bought it it has made this sound. It only happens when the car is completely cold and only happens for about 5 minutes when you push the RPMs to about 3k. Then....it goes away. Its a relatively minor annoyance but for those first 5 minutes its extremely embarrassing.

Any thoughts?

Nice. I've searched different forums before and could only find other TSBs that seemed close but not exact. This is exactly (I'm guessing) what my problem is. Thanks!

I also just bought an 07 GT month ago and have 30k miles on her. I also have the same issue around 3,000 RPM I get the metallic rattle. I'm 99% sure its the issue that TSB 8-2-10 will fix. I just need to find out how much it will cost for the dealer to fix it.

Also check the exhaust hangers on the transmission mount, mine did the same thing and i found out one of my bushings on the hanger was messed up.
