2017 Silverado 4x4 At idle there is a chirping noise coming from the bell housing area.  Has anyone else had this problem and if so what is the fix?

High pressure fuel pump under the intake manifold.  There's a big thread about it in this forum.  I have the same issue.  Going to dealer with info from that thread.  The sound from the pump reverberates through the back of the engine, down the bellhousing.  I traced the sound the same as you.
