Hey, my 17 Silverado is doing the same...sounds like a rattling heat shield with light brake apply. I checked over every single splash shield, heat shield and skid plate that I could..I shook down everything that I could and couldn't locate the noise. It also almost sounds like a rock or something between the backing plate of a caliper too, but it's not. Just would like to know what the OP found was the problem, and if it was internal to the transmission.
