Learning this new rig.. Transmission "ticking" ?

[Gmfm]

Pretty sure its a high pressure fuel pump. Mine does this. Its loud it literally ticks every second and doesn’t speed up with throttle. I ran a stethoscope everywhere when I had it raised, the ticking was especially loud on the fuel line headed up to the bay. I’m guessing its loudest in the back on the passenger side?

Same ticking for my 2015. Been doing it since day 1. Never an issue.

I believe I am familiar with the idle ticking. It is consistent on my 2019 5.3 and a relative's 2018 5.3.

When it stops making all sorts of sounds that when we have to worry. Until that point, drive it.

Never realized how loud the ticking was in the hot months until I pulled up to the drive thru window at the bank and dropped my window. In that partly enclosed area it was really loud.

My Tahoe makes the same noise from the same area? I was told it was the Exhaust manifold bolt being loose. Do you have a video at all of the noise?
