I read through here every day, great site. Came over from the 6.0 side after spending $15,000.00 in repairs over the last 3 years. Now I have a 2002 f350 4x4 crew cab dually with the 7.3 and 4r100 transmission. No trouble till yesterday while pulling a heavy trailer with mini excavator in it, the o/d light started flashing and the a/c quit working. Got it home and pulled codes p0750, p0755, p0743, p1754, p1747 with AE. Found the wiring harness had been rubbing on drive shaft to the front end and broke three wires and skinned two others. Fixed the wires but that didnt change any thing with the o/d light or a/c. My question is do you think that fried my transmission? or something else?
