I bought this sweet dually for four thousand dollars from a customer of mine or decided it was not worth the cost to repair trans. I have known truck since he bought it and always admired it. I all ready have four 7.3 trucks and know them inside and out so this was not getting past me. The torque was noisy and the feed bolts above the valve body came loose and caused no pressure in drive gear. I replaced converter, fixed feed bolts and added trans 6.0 cooler and PHP Hydra chip to improve towing.
