I have been told by several that when hauling heavy loads 12-15K that I should run the 4R100 out of overdrive in third gear.. I know that when I 'am hauling it does not always kick down easy when running in stock or especially when running the TS-Chip in 50 / 75 over stock.. Any body out there towing with a 7.3 that can give some advise on whether the over dirve should be OFF or not? I run the mountains all the time hauling horses and if running means over riding over drive while hauling then so be it. I just want to make sure that I 'am doing the right thing nd do not want to do anything to damage the truck unnecessarily.
