I have a 2014 F-150 Supercab 2WD model with 3.7 V6 and auto transmission with 40,800 miles on it. I had the transmission serviced a couple of weeks ago (1,000 miles ago) at a Ford dealer since it’s still under the 5 year/60K mile powertrain warranty and occasionally after making a hard stop and I press the gas pedal to go, it will stay in neutral for a few seconds then slam into first gear. It happens from time to time. This doesn’t occur if I make a soft stop if that makes sense. I’m curious whether the transmission fluid exchange could have caused this? I’ve not brought it back to the dealer yet. I thought I’d pick yall’s brains first. ---

If such a thing is possible, give your tranny the old "drop the pan, replace the filter, and refill w/fresh fluid " treatment. That’s where I’d start with that problem. I have an older Ford truck configured with an automatic, and the symptom you are describing is one I had develop about two weeks before it went into the shop for a complete transmission rebuild. However in your case, at 40K miles, unlikely to be necessary. The only other thing I can think of is when my truck’s driveline lube has started to dry up, it will sort of make a bang noise and seem to “jump” into gear after a complete stop, say starting off after waiting for a red light. That’s caused by the slip joint splines in the driveline sticking. Or the limited slip differential needing the friction additive replaced. ---

this is pretty classic symptom of an underfilled transmission. Have you checked the fluid level? Is it leaving puddles anywhere? ---

I agree with eddo; it sounds like an underfilled transmission. I’m also pretty certain this one does not have a dipstick so… If that is the case then it needs to be corrected ASAP or you will be needing a new transmission.
