From P to D pedal rumble

So tell me if you truck does this I dont know what it is. This only happens when the truck hasnt been warmed up so if it sits for a couple of hours when I shift into D and accelerate I feel this almost vibe or rumble ever so slightly like somethings turning on. it's consistent and never does it after the engine is warm just the initial acceleration from sitting. Any ideas? its a 2020 w/ 34K just bought it last week any help would be great!

You should be able to find threads about it

 

Awesome yeah it does sound and feel like a computer of some sorts and yes it does it immediately when I start rolling, thank you!

 

It happens at about 8mph if I recall.

 

Mine kicks in at 15 mph

almost like a thud
