Engine Rattle and Drive Trane clunk on a 2018 5.0 150
I have a 2018 150 with the 5.0 and I have a couple issues and was wondering if any else has these. 1. if a step on the gas lightly and release i hear a distinct rattle every time, i can hear it plain as day or if i slow down and get back on the gas i hear it 2. About every a few engine start ups i hear a clunk and can feel it for sure like the drive shaft slips then catches, not sure if these two issues are related but 100% i can hear both issues no problem

I have a 2015 5.0 with a similar issue. When I accelerate hard from a stop there is a distinct rattling sound. Also, shifting tends to be very clunky, sometimes enough to jar the entire vehicle. I brought it to Ford several times. The first time they said it was low on transmission fluid (only had 35k miles), the second time they said the solenoids were bad and replaced them, and the third time they rebuilt the entire transmission (under warranty of course). After the third time the issues were gone, until about two weeks later they started again (mostly shifting down from 2nd to 1st, and up from 4th to 5th). Now, I have flashed the truck with a 5star tune and while the performance is great, all of these issues are much more noticeable. So now I am driving without the tune and confused about what the root cause. Also, my truck was manufactured in Canada.

Rattles each time gas pedal lifted for first few minutes of driving after a cold start.
Apparently timing chain slapping around... if I let the truck warm up before I take it out, I don't seem to encounter this.
Loud metal on metal clunk just as engine fires up at end of cranking. Suspect it's the starter disengaging...
I don't suspect drive shaft since obviously the truck is not in gear... really only notice it if i use the remote start.

The engine rattle on deceleration is a common issue, ford released a technical service bulletin to address this issue (TSB #18-2354). Heres a link to a good video on it and theres also a link in the video to the TSB.
As far as the clunk on startup, my 2018 does the same thing. Not sure what it is or if its related, I have an appointment next week to get the rattle issue taken care of, I'll report back on the results and if it affected the startup clunk also.

Engine rattle by tipping off the throttle is largely documented guys. Search this forum, you will get a ride for your money. My personal take: the truck is built like this, nothing to fix.
About the clunk at startup, I noticed that too. I think
it is related to parking brake (mine is electric): it could be the sudden, but very short, torque spike transmitted to the wheels at startup. If engaged, the parking brake acts against this torque spike, resulting in a clunk. If parking brake not engaged, no clunk at startup.
let me know if you experience the same thing.

I got the PCM update done on my truck today, the rattle is totally gone. Overall the engine sounds better and the truck drives a lot better when its cold.
As for the clunk on startup, its still there. One thing I've noticed, the amount of pressure I put on the brake pedal during the start seems to make a difference on how hard the clunk is felt. What I mean is if I just barely press the brake pedal the clunk is a lot more noticeable vs if I put heavier pressure on the brakes when I hit the start button.

It is my understanding that the PCM flash fix the rattle
when warm and with transmission in Neutral.
Could you confirm that your Rattle is gone while the engine is Cold (first start of the day) and with transmission in Drive?
