This is about F450s and may not apply to 250 and 350.
Last Friday, 4/6 I got into my truck to go home from work. I had ran a couple of errands that day so the truck was still warm and had only been parked an hour. I made it 2 miles and the screen went black with big orange letters saying "50 miles to 50mph limiter, exhaust system fault". Then the miles started to count down from 50.
I went directly to the dealer which was 31 of the 50 miles and the count down was at 19 when I got there. The truck had set "a federal code" according to the tech who was checking it out. "This code can't be reset" he said. There was a temporary failure of the nitrous oxide sensor that set the code but the sensor was working now. The truck must be repaired and then driven for 15 minutes without another failure and then it resets itself, I was told.
So, the tech began downloading a complete set of codes for EVERY computer on the truck!! He told me there was an update for the TCM too. After about 90 minutes of reprogramming everything he said to drive for 15 minutes and see if the warning and countdown went away and if not to limp back. He had also unplugged the sensor and put new grease in the plug while waiting for the downloads.
Sure enough, 15 minutes down the road the dash cleared and has been fine since. I have driven about 350 miles since then.
I want to say again, and the tech even told me this, the F450 uses much different software than the 250s and 350s do. My point is there is an update for the F450 transmission and I can already tell it is a big improvement.
You might like hearing this too, , , , , , when the tech first introduced himself to me and started working on my truck, , he said "these are going to put me out of a job soon, , , we don't get them in for anything but service". He was talking about the 6.7 Powerstroke trucks!!! I told him not as long as they are trying to quit running in the middle of the road with only 2360 miles on the clock and he said my truck was the first he has had ANY issue with. He is the Powerstroke tech at a very large dealership and does all the software work.
I guess that made me feel a little better but a couple hundred thousand miles on my truck, trouble free, would make me feel a whole lot better!!!!!!
