Mac,
You can't fix it without changing your entire swing. It starts with your "faulty intent", then flows through your hands, arms, body, and finally your leftshoulder. Secondly, it's also influenced by any other faults - that require you to do that in order to hit the ball where you want the ball to go.

I can't speak for the intent in your case, however, the right hand under/ palm up through impact, then leads to parallel hips and shoulders, leading to axis tilt issues, creating your high shoulder. If you are looking for one piece to fix the puzzle - that's a problem. You need to understand the whole thing and be willing to change it. If something opens the blade then something else needs to close it - to keep it where you want it - same with clubhead path. So, you have alot of things that prevent the ball from going left i.e. the rear palm facing up through impact, you need to find the things that are wanting to make the ball go right and get rid of those- one such item is the lead arm coming across the chest too much during the downswing.

Here's the quickie thought - if you have better horizontal hand motion through impact (by the way that is something you would allow to happen - not just do it with you hands) then not changing anything else - the ball goes to the left , now if you learn to turn through it better, lag the left arm up the chest more - although you have more turn with the pivot - you actually keep the face from closing - as the more the lead arm (tired of getting the Smilies for you) hasn't come back across the chest the more the clubface stays open. That's why you see the strong grip guys have larger turns through the ball i.e. Duval, etc.

It's a long term project - if you measure it by day to day ball flight - you'll never make the change. You have to have a conceptual framework of how the different parts work together in order to really make the change - it's a pattern - not a movement of one part or position of one part that you are concerned with.
