I did mention thta torque converetr to them and they just said. O no we know about that problem and we are sure you don't have that. before they even test drove the truck.
The tech claimed "my heat shield could be vibrating causing the noise" until I brought up the "star" case and called him on the heat shield, since it happened at the same rpm no matter the speed. After speaking with the service manager I was able to get them to upgrade me to an RT torque converter because the tech was being difficult. You are correct, the exhaust is under warranty as well (as long as it is stock) so have them check the exhaust and see what happens. If it eliminates the noise then great, if not then its on to the next step.
