I have a tune, headers, intake, tb, HF cats, and my rear end clunking noise could not be fixed by changing the fluid/friction modifier.

When the dealer decided they wanted to open up the rear end, they had to send the file to GM containing a snapshot or w/e of ecu. GM gave them the go ahead, even with my tune, and they replaced the ENTIRE rear end. Total would have been $1,750 and I got a new rear end with the rest of the car at 25k miles.

So dont give up hope if you think your mods or tune actually didnt cause the damage.

Absolutely. Like I said in the opening post the Magnuson-Moss Warranty Act (15 U.S.C. 2302(C)) still applies. They can not deny a warranty repair unless the issue in question is the direct result of the tune.

Thanks.
