Hello like many others I now have the transmission failure. P1747 code. Will not shift at all. Will start just not shift. F1 pump comes on. When using the paddles you can hear something maybe trying to shift. My Autel 906 will get into most functions of the car but is really not telling me anything. When the problem started the car was driving fine and just came to a skidding stop and has not moved on it's own since. I have changed the f1 relay no change.
