How about symptoms? Codes don't necessarily mean squat without symtoms. low fuel pressure can throw trans codes.

don't know exactly what happened, I know it was cold, and he got on it a bit. I am not sure if it limped or not, but i think he might have said it did.( happened a week ago or more, just pulled the code)

Ya had the same thing happen the same way by the sounds of it. I called the dealer and they want me to take it in for them to read the codes. Mine also said PO700 transmission control system, 01024 lost communication with transmission.PO846 the transmission pressure switch solenoid D cht stuck open. So I'm looking for the same answer as you. I got the codes cleared it lasted a few days then on a cold start few days later they came back. I let it rest overnight and the limp mode went away but the engine light stayed on. So will wait and see if we get some answers here.
