Hey I have seen some very informative post from you and have a question for you if you don't mind. I have a Ford 7.3 and run the Torque app with the Trans Fluid PID you have posted. Mine seems to measure the internal temp of the trans. I have checked both the pan temps and the return line temps with a laser thermometer and these temps are about 20 to 30 degrees less than what my Torque shows. I pull an 18,000 lb fifth wheel about 15,000 miles a year and many of these in the mountains. According to my Torque, I should have burnt my tranny years ago. Is there any way of calibrating the PID so the Torque will show 20 degrees less? I know I can just adjust mentally but I am too OCD to like that. I have a computer background so I know to not just mess with stuff without asking an expert first.
