Vibration when slowing down at 23-26 MPH

[New chevy 2010]

2022 Silverado Crew cab 4x4 2.7 with 8 speed. When slowing down, around 26-23 MPH truck has a quick vibration (like driving over rumble strips) every time when it downshifts. The engine RPM is around 1200 at the time. Also, below that speed the truck feels like I’m driving on a rough road even when it’s smooth. Dealer stated we couldn’t find anything concrete. I have seen other complaints for this, but I can’t find what the solution was. It’s smooth when accelerating unless I stop around 23 MPH then I can feel the vibration. Anyone have this problem? Thanks.

I had the same vibration on deceleration at that speed after I leveled my truck with 2" rear drop shackles. I added 2° angle pinion shims and it went away.

Thanks, mine is stock. It’s driving me crazy. It sometimes feels like the vibration reverberates through the cab.
