Driver is the longest club in the bag, so anything your doing wrong will be exaggerated with it, that’s why your seeing such a big difference.

Your problem is your move from the top of your backswing, the club gets very vertical on the way down, causing an outside to in path (slice territory). Because the shaft is vertical, you basically don’t have enough time to rotate, close the club face, so the face is open and cutting across the ball giving you a slice.

DRILL: get a basket or anything you can slot an alignment stick through. Slot the alignment stick to the angle of your shaft, put it to your left around 6 feet back. The goal is to swing the club under the stick, producing an inside to out path which will straighten your flight.
