Shifting issue...

[Denali2k8]

Anyone? I don't wanna just start throwing parts at the truck, but at 87k miles, I debated plugs and wires and go from there.

Throttle position sensor? Factory tune? Ideas?

This normal?!?

Completely normal.

Completely normal.

It kills me inside, so different than traditional thinking etc.

Did you see the fluctuation in the rpm? Idk what to do first...

Do I see it in your video... yes

Do I see the fluctuation in my truck... no

I would think TPS or, hate to say it but, torque converter.

What kbuskill stated is accurate. Mine does the same thing and at first it annoyed the shit out of me. After talking to several Chevy techs and reading a bunch of posts on here it's normal for yukon and tahoes to fluctuate on the voltage. Exactly what Kbusskill stated is spot on.
