I have a 2014 Silverado 4x4 LTZ. Great truck but It wines. Very annoying. Reminds me of how the old power steering pumps sounded when they were low on fluid back in the day. I'm told it's the transmission pump. It's normal and nothing needs to be dun. But it's annoying as hell. Is this really normal?? And is there a fix?? Truck has 85000 on it and it runs drives and shifts great.
