When I go in reverse the noise isn't there it's sounds like dry metal rubbing.
Going away in reverse, it could still be rock in the caliper. However, going away when the truck shifts ... I can't think of anything in the front end that would be gear dependent. As for the transmission, an automatic would generally show other symptoms (slipping, clunking, etc). I would probably run it into a les schwab (they do free brake checks) and have them look for a rock. If that is it you get it fixed for free. If not that, I would climb underneath and start looking for what is rubbing. If it is enough to make a sound, you should be able to see a spot somewhere that looks shiny and clean where the rub is happening. Good luck!
