07 F-150 trans fault
Truck in sig picture, 5.4 liter, 4spd, 4:10 rear. I know I'm towing at max CGWR of 15,300 or better, but this "trans fault" has been coming on with more regularity in the last two years. This weekend ...

OH, great! Not too convenient to reroute my camping trip to the nearest Ford dealer and let it idle while they find time to help.
Why would you have to leave it idle? When the light is on a code is stored in the computer. It will stay in memory for about a month after the last time it flashed. If they tell you they can't read it when the light isn't on, they are right, they can't. A competent tech can, but they can't.mosseater wrote:
On a brighter note, I found several references to the same fault display and one guy who had his fixed. Turned out to be a temp sensor in the pan. Unfortunately, they dropped my pan and changed the filter when they did the last trans service. Hate to go back in just for a sensor. If I can find out which one and where, I might give it a go myself. After that spark plug fiasco, this should be a breeze.
You're going to start changing parts based on what was wrong with somebody else's vehicle? Good luck. There are at least 50 different reasons that the light could be on. You could spend thousands in replacing good parts before you get lucky and change the right one. Get the codes read and then I can help you find out EXACTLY what's wrong.
Actually, no, though I can see why you thought that by my wording. I've been in maintenance and repair for most of my career, so conspiciously absent in my response was the inference that I would need to know with at least probable certainty, which sensor and where before I go about changing it. That was the "if I can find out which one and where" portion of the sentence. I'm not a parts replacer. Never have been. Now, OTOH, if the probable cause points to a particular part with relative certainty, and the cost of absoulute confirmation will outweigh the cost of the part, then yes, maybe I'll be a "parts changer" in that scenario. Depends on the part and difficulty of replacement. I have worked with parts changers. Am not one. That's not trouble shooting and many times does not define the root cause of the problem. That is a road to expensive disappointment. Sorry for the confusion.
