I have a 2001 7.3 and up until a couple of weeks agao truck would pull just fine. Now when I hook to our 20' gooseneck with the asphlt paver on it roughly 15,000 pounds the truck will barely puul out of its place. once i finally get going my tranny temp goes sky high everything else is fine. Just rebuilt the turbo, all intercooler boots are ok, replace accumalator body in trans and im going to replace the icp sensor and harness on monday because mine is caked with oil. Ive read on other post maybe bad torque converter or cracked flywheel but im clueless and i really need this truck. Any help will be much appreciated!!!!!!!!!!!!
