I have just started to monitor my Transmission Fluid Temp(TFT) and I was able to get to 250*F on the FWY after about 30 minutes. Talked to my FORD SM he said that the operating temp should be 200-220*F so I got worried.
I just talked to a FORD AutoNation(Electric Dealer)SW who talked to Transmission Specialist who looked it up and said it(Transmission Electronics) will trip a code at 301*F and come up with a wrench symbol. I'm surprised that it could go that high without hurting something. I'm not really having any problems with the Transmission.
