For stock configurations, go to Frahm Dodge in Norco and ask for service advisor Patrick Foley. The Tech you want to request is Tony, he is their best Diesel trouble shooter. The owners son has a 06 that is tricked out, so they do have an understanding of after market mods. The transmission specialist just beefed up the 48rfe that the owners son drives so they do have knowledge in that field. The trany guy's name is Jeff in case your interested.
They are the only mechanics that work on my trucks and as long as their in business they will be the only shop that work on my trucks.
