Do you mean the ball only goes 50 or 60 yards or does it go to a height of that and then make a decent distance? If it is the latter that isn't necessarily a bad thing. Many people would hit the driver better with a higher ball flight. It all depends how far you hit it . Most problems with the driver happen because people are trying to either do something different or try to knock the cover off the ball. Just tee the ball level with your left heel (or even more forward, especially if you are tall) and swing normally with a good weight transfer to the left at the start of the downswing. You will automatically swing up on the ball a little (in contrast to the irons where your club continues to go down after you hit the ball. Most of it has to do with where the ball is positioned in your stance. Try to maintain the height of your hips and the top of your spine through the swing. The game is complicated enough without trying to make it even more so by adopting different swings for different clubs.
