I have pops, under load with 5.0, 3.73 gears and 10 speed. Seems most obvious from 6-7 gear in full auto. Also, I've had some hesitation shifting up/down after hard throttle and pulling off suddenly. I'm not sure if this is just me getting used to this tranny/engine combo or something actually wrong here.
To be honest, all I really need are 8 gears.. I was half heartedly joking with my buddy when I said; My truck is too big for a small town... Before I get into 8th gear I'm already at another light or stop sign. I find myself locking it out all the way down to 6th gear so it's not all over the place.
If I'm hard on the throttle in sport mode and hammer it to 50mph roughly from a stop and let off, I get thrown forward as hard as I did backwards, cause it's only into 3rd or 4th gear.
There's no doubt a learning curve with this thing. I knew exactly when and how to maximize my 6 speed to get that engine right where it loved to be.
I'm a 1,100 miles into it and I'll admit I have a way to go still before I drive it, instead of trying to catch up to what it's doing. I'm not of course talking about just gas and go, but driving it as if it were a stick almost and where the engine's power is.
I'm getting the feeling when guys are saying this powertrain was thrown together, that maybe they're overwhelmed like I was at first and still kind of am with so many choices...
For instance., before I even start to drive, I kill the start/stop, then lockout 10,9,8 and 7th gear. Then I think normal driving or sport.. but wait let's see how she drives with Tow/haul selected. Then I get a vibrating steering wheel and shut off lane assist... Jesus! I haven't even been able to change the radio station yet, before that damn faint click takes all my attention away from everything...
It's not hectic like that every time but it has been. So I can see why guy's want there simple 5.0 / 6speed back again.
Uncle G. I wouldn't rule out a motor mount. On the the other hand though it's not a real metal on metal noise. For example my sister would never hear it, but my Chevy loving buddy who would love to point out anything wrong with my truck, would ask immediately what the hell is that noise.
Again the best I can describe it is; If you took the handle of a screwdriver and as soon as you let off when you get to 30mph or 40mph tap the handle against the anything plastic near the passenger side floor.
To be more precise, I would say the top left of the passenger footwell.
Not way up under the dash, but about even with the bottom of the glove box and straight In.
I'm not even sure you could hear it on the outside if you were in a car next to me. It's that quiet, but it is not something that I hope Ford says: Oh yeah, that's normal now for a part to click while your accelerating..
What's a pia is everything else about my truck is awesome. The body lines are perfect, the suspension is tight, the B&O rocks without any rattles or speakers cutting out (Ford's door harness 04-14). The doors shut solid which is saying something with a Scab. Everything is spot on, except for that damn click, which again Boosters is not the 5.0. I'd bet my house it's something outside of the engine or around the union of the engine to the transmission.

I would ask the shop to check tranny mounts also.

I spent a good 20 minutes under my truck looking at everything underneath.
Which this is actually the first time I haven't had skid plates and I can see those ridiculously vulnerable tranny lines.
I pushed and pulled, rocked anything and everything and nothing, nothing at all looks like the culprit.
I could find the the clamp for my GoPro at a moment's notice for a year now, except this week... I have no idea where it is, driving me nuts.
I gotta say, I'm happy I coated everything underneath and all things suspension with Fluid Film.
It has kept my truck still looking almost showroom clean underneath. Even after 2 decent storms these past 5 weeks, the differential is still nice and black
I thought about it after winterizing the Sea Doo and seeing how spanking new it kept the engine looking, after 6 hours of salt water getting in the bulkhead.

Auto Start Stop issue
Other than the occasional rough shifting especially when slowing down at around 30mph, the only issue I’ve had is with the Start/Stop feature. Sometimes, when the truck shuts off, and restarts, it seems the starter has trouble starting it and almost kills the engine especially if I then press on the gas. The engine almost killed at a light today after restarting. Anyone else have this issue with their ‘18 5.0?

So far no fix.
So an update on my 18 5.0 XLT, they have had it for 21 days and replaced the vct solenoid and valve cover gasket, and the cam phasers were finished today. Less rattle but still the same. No idea what the next step is. Dealer will call me tomorrow.

Drew, I have the exact same thing going on. I can say that my click/snap isn't always the same volume and I can actually manipulate it to make it happen.
If I accelerate then slowly let off, I can' barely hear it, or it's not doing it.
What I can do is get up to 20/30 mph and let off totally and it's loud, right on cue every time. I also can feel it, which feels like, under the front of the passenger footwell.
If I'm cruising along normally at 35 or 40 mph and give it a little gas and let off, I hear it again, every time.
I've been under the truck 4 times now and I can't find anything, plus it has to be moving. I can't just rev it in park and hear it.
Aside from that, everything else is great. I wouldn't discourage anyone from this powertrain.It's not the engine we're talking about it's the transmission.
It's the standard combo for the Platinum now.. I think Ford is plenty confident with this powertrain in basically their top of the line package.
We'll figure it out eventually and all will be fine..! It has been for 13 straight years, in 4 different trucks.
On a side note. I'm willing to bet if GM didn't have their hands in or around this 10 speed, there would be no issues.
Two friends, one with a 2014 Silverado and one with a 2016 Silverado. A total of 17 combined recalls with their transmissions.

I hope the 6 speed is still available with at least one engine next year to add to the fleet.
