Greetings to all ..

My 05 with 272K and the Z71 package makes a noticeable noise when shifting between 20 - 25 MPH.

It only happens under casual acceleration, if I lean on it there's no noise.

I've asked 3 other owners of similar vehicles/years with the same powertrain and they all say that there truck does it too. "If it ain't broke, it ain't broke."

Am I just worrying too much?
