So I recently overhaul a 4r100 in an 01 F250 4x4 PSD and its become a bit of a headache. Came in with p0708 and p0713 and had water in the unit, forward and intermediate clutches were smoked and it didn't move. So fast forward...rebuild is done, truck shifts 1-2-3 fine, with the blinking od off light it has no OD and No lockup due to the trans temp sensor code. If you unplug it and let it go into failsafe (4th) it has a good 4th gear. It air-checked before assembly, has all the gears and I have put 2 NEW OEM Ford solenoid packs on this thing so far. With the modis Hooked up, the trans temp sensor (idling in park at operating temp) will read 5deg-8000deg (you read right) and jump back and forth sporadically and anywhere in between. New MLPS and it too throws the same code. Reset computer and am still getting this problem. Clear codes and it will come back instantly. It does have a plethora of other codes but I do not believe they pertain to this problem. Came in with said codes...thoughts on where to start? BTW I did check the harness out...no kinks or exposed wires from what I saw.
