I have a unique problem on my 2007 Tahoe with a Z71 package and 200 000miles

Press the button on the dash so you can see when your Tahoe is in V4 or V8 mode. If you notice that it vibrates in V4 mode, it is most likely the AFM. I had the same problem in my 07 and it went away after I disabled the AFM. I now have full time V8 and no more shutter.

Happy to report... That I just installed my BlackBear Tune... It is what we needed all along, vibration is gone...
Tahoe runs a whole lot better, and I should have done this years ago....

If you don't have a BB Tune... Don't wait do it

I'm glad the vibration went away after you disabled the AFM. The bills in the mail...
