A good friend of mine just picked up a 2016 Yukon xl with the 8 speed. After driving it a couple days and getting it good and warmed up, the transmission notably shudders in most shifts. 130k miles on it. Google tells me this is a known problem and a class action lawsuit hit at some point.
I suggested 1-2 drain fills and possible dose of lubeguard. He’s going to start with 1 d/f and see where that goes.
is there known remedy at this point for this unit?
