no shift p0705

[brycer]

i have a 2000 f350 7.3 with 4R100. soon after i bought it the tranny was staying in second gear all the time, with some talking to brian at BTS i found the alternator to be bad. so i got a new alternator and everything was fine.... drove it for a day or so with no issues then all of a sudden it takes off in second gear and i know if it does that it wont do the 2-3 shift. i put a scanner on it and i get p0705. i got a brand new oem ford trs and put it in cleared the code and same problem. now with searching around here i have found that this code is normally a wiring problem. i have looked over all the plugs and i dont see any issues. I now have the entire transmission harness out of the truck to look over all the plugs and i still dont see the problem! where is the normal "problem area" with the wiring in this truck? please heeeeelp

STILL having issues with this, after looking over everything on the harness and not finding anything i put it back into the truck and it worked great for about two weeks....then today at lunch the trans goes into limp mode just like before....need help finding if there is anything else that can throw the p0705 transmission range sensor malfunction code.
