I have an 02 f350 drw 7.3. I have a Hercules transmission and torque converter built. I got about 2500 miles on them when my over drive light started flashing (po743). I call the company and they sent me out a new torque converter and solenoid pack I changed them same thing I also noticed that my heater blow and my exhaust brake was not working so I got new fuse panel and pcm still the same thing so I changed all firewall grounds and transmission ground still the same thing. Any ideas from anyone out there. Also can I take the 6 grounds that go to pcm and hook them straight to the ground post on battery?
