The power source for the transmission is in a fusible link at or near the engine batteries, oh there are so many things that can set that code, there was a tech repair notice sent out on that where the factory had the wiring harness pulled to tight at the fuse box (if yours is in the engine bay) and it would crack the inside of the 10a fuse for transmission and by a test light you would still have power on both points on the fuse, it was breaking the fuse at the leg, replace the fuse anyway there cheap and see if it works,I have found 3 times where this happened
