2007 nissan pathfinder does not start, pulled codes, found p0717, trans circuit a signal, and u1000, network com circuit, codes. Blown tcm fuse, coolant mixed with transmission fluid. Fried tcm...
UPDATE I made this video before the NISSAN TSB was issued to my software. The real issue was defective radiator/trans coolers. Bypass the radiator and install an external trans cooler to avoid this problem. You might get lucky if you flush out all the old coolant with simple green and the old atf several times to eliminate the water shorting the tcm. but more than likely you will need to replace the tcm or possibly replace the transmission. sorry for the confusion, as i didnt see the tsb prior to this, and I diagnosed it on my own without outside prior experience for this case. I did see similar failures due to neglected, rusted or corroded cooling systems before with bmw, and gm vehicles ect... in the past. thank you for watching*
Do me a solid if this helped, and follow me on instagram.
