If this left shoulder just moves up and not back I’m gonna get really stuck

So this left shoulder on the down swing,if my left shoulder moves down and back,then be really out to win probably causing a slice,if this left shoulder just moves up,and not back I’m gonna get really stuck,and my arms and wrist are gonna be forced to hit the ball,so ideally we want this left shoulder to move up,and back at the same time,that’s gonna help,square my path and allow my arms and wrist,and hands to be more passive.
