: The key is it stops when you let off the gas. That points to a gear setup problem.
: When I set up gears I have tried to run the pinion depth a little deeper to move the contact pattern so that it is ideal under full load (heel emphasis). This reduced pinion depth (thicker shim) causes whine on accel, a little during constant speeds, and is quiet on decel. The second photo on the link below illustrates this.

Thanks, and nice site. Love the truck!! Heard from a guy in AZ who had the same noise, dealer told him it was normal from the HD tranny breaking in and would go away. Sounds like dealer BS, but who knows? I have a 3 yr bumper-bumper warranty on this thing, so I'm gonna let it go a while and see if it gets worse.
