Had a similar thing happen on my Ford Ranger a few years back......although it was not a Super Duty...obviously.
Would not move under hard acceleration....only could get it to crawl with low accelration and then it would buck and kick like the tranny was slipping then catching.
I thought geez man...can't afford a tranny. Turned out to be a speed sensor on one of the wheels. Even though they seem to be related to the ABS system they affect the tranny also...maybe in when and how to shift. So....under $200.00 later all was good.
Never had any lights on..no ABS...no blinking CEL which I think the f-150 gets with a tranny issue.
So...just saying....if it was fine one day and then the next day all of a sudden feels like a tranny failure and you literally did nothing from one day to the next...think possible sensor or solenoid.
Every modern vehicle with ABS brakes has some sort of speed sensor and dang things cause odd issues when they fail....the three I have had go always showed up like tranny issues. Only once did I get any kind of a warning light.
Had em f go on the ford....my sons Sentra and this past winter on my Sonata. The Ranger I described. The Sentra would not shift above 2nd gear and the Sonata, since it was a 2011, the computer fail safed to only 30 MPH or less and was the only one of the three vehcles with a warning light on and that was a traction control light.
So...just saying....weird stuff when they fail.
Professing themselves to be wise, they became fools
