Quick update. I had my 18 5.0 w 10 speed in for the recall inspection and asked them to look into the popping sound I'm hearing when it's shifting. They didn't fix the sound but did upgrade the PCM (not sure that's right) and reset everything and told me it should be better after 500. So wait and see I guess.

Did they acknowledge that there is a noise at or around 30mph?

Acknowledge is a strong word, they dismissed it by suggesting it will be resolved with the update to the pcm. Yeah, I'm very skeptical.

As am I.
Seems that it needs a mechanical update, vs a software update...
Let's hope so tho.

I started the 17 3.5 rattle thread and I'm currently in the process of a buyback, 30+ days in the shop new phasers, cams and tensioner as well as a PCM reflash and the noise is still there. I believe it to be an oiling issue to the cam phasers on cold starts but ford doesn't seem to have a fix for it, I may go f250 if I stay with ford but the current state of the f150 doesnt sit well with me.

My truck is currently in the shop for this same noise. 2018 5.0. It is loud and I can reporduce it time after time, but they still claim they have not heard it. Had my truck 2.5 days now and I am heading over there this morning to drive it for them. To me it sounds like a metal on plastic sound....

At least they gave me a loaner, and the 2.7l in it is impressive, but I am starting to miss my truck.

3000 miles now. Still getting the popping sound during shifts in the 10 speed, I'm also hearing a slight metal rattle kind of sound on low shifts. I really can't hear the rattle unless I'm driving next to something that reflects sound, like a glass store front and I have windows down. To be completely honest, I'm not real happy with this situation. The loud popping sounds and the occasional harsh shifting is getting a little tiresome and old.

Just left the dealer. They think it is the throttle body closing or trying to close, but did not say for sure it was an issue (didnt deny it either). Going to drive some other 5.0L trucks and try to replicate. I'm thinking now it could be something in the intake that is loose? Will update when something changes.

That may be the exhaust note. The throttle body is closed instantaneously between each shift to lessen transmission internal clutch wear. In other vehicles, the sound is akin to how a motor racing car sounds between shifts, only in motor sports they are usually mostly unmuffled and therefore much much louder.
