When the weather is below twenty degrees the "wrench" light will come on . Symptoms include no rpm increase even if the throttle is pressed to the floor and the no transmission engagement or it will move ahead very slowly. After it is warmed up I can shut off the key, wait ten seconds and most times it will behave normally. Two codes were flagged P0701 and P0730 but they go away after a hot soak. I have seen other posts with this but not a definitive answer.
