Just answered this in another thread, but I recently changed mine with AMSOIL about 1500 miles ago. Looks like you basically have the same setup as my Rebel with the 5.7 non-Etorque, 3.92 rear, no 4Auto. This is what I paid (with the AMSOIL membership) for fluids, and if you've ever done these changes before all 3 will take you about an hour if you're crawling around on the ground beneath the truck. Spent last week in Memphis driving around in snow and ice constantly switching between 2WD and 4Hi at speeds up to 60mph. No issues/whines/clunks.
