Here's two drills that should help you.... Goog Luck!!

The Box Drill

 Uses

This drill is a must for any over the top swing where the upper body leads the forward motion.  It will provide instant feedback for errors in the swing path.

 SET UP

Find a golf club box if you can, if not, a shoe box or any cardboard box will do.  Weight it down a little so the wind won’t cause it to move.

 PURPOSE

A drill which will help anyone swing more down the target line and through the ball.  You will become conscious of keeping your head quiet and looking for impact.  This will lead to better ball striking and scoring.

 BENEFIT TO BETTER PLAYERS

Generally used early in the season or that mid season slump where the weak fade might work its way into the swing due to swing path errors and changes in swing plane.

 DOING THE DRILL

Place the box just outside and parallel to the target line.  Place a ball near the middle of the box with just enough clearance for the club head to make center contact while missing the box.  Make full swings.  Feedback is immediate.  If you strike the box before the ball, the swing path is out to in.  Continue hitting until you make solid shots without contacting the box.

Now do the drill below after you have mastered Drill #1 above, that being... you're not hitting the box anymore.....

SWING THROUGH THE GATE

 USES

This drill helps correct the chronic pull slice and also improves the club head path and shallows out the angle of attack.  Also helps get the lower body clearing to allow the path to be more in to out rather than out to in.

 SET UP

Place two tees into the ground at about a 40 - 45 degree angle open to the target line about 6” apart.  Tee the ball in the center of the two tees and swing with a mid to long iron fully without disturbing the outer tees.

 PURPOSE

This drill is designed to correct your over the top move and create a path of the hands and club head into the impact zone from the inside of the target line.

 BENEFIT TO BETTER PLAYERS

The better player will soon realize the lower body must initiate the forward swing and the arms and hands will follow the body’s lead.

 DOING THE DRILL

The feeling must be of swinging the club through the gate from inside the target line to prevent dislodging either the outer or inner tee.  If grip pressure is relaxed, a proper release will occur and the ball will show a draw tendency starting to the push side then curving back to the target.  You should get the sensation of clearing the hips by initiating the swing with lower body rotation and not allowing the arms to get out and separate from the body as they swing down.  The hands may feel close to the body through impact.  Be sure to see club-ball contact and you will begin to feel effortless power and improved ball striking ability.

Practice, practice practice.  Hope these help you. 

yea it was getting so bad that I was doing the same thing along with closing my shoulders more and it was causing me to hit a nasty hook or I would try and catch up and when i flipped the hands over my shot was unpredictable.
