New guy here from west central bama. New to diesel pickups just got mine Friday. Been into semi's since I can remember.... Do all my own work on my Cats, been all the way thru several 3406b's but I learned on the old E9-500 Mack V8's. Anyways, new to the Duramax. This will be my daily driver and I don't plan to go too wild with it, trying to keep from putting a tranny in it....
