I hit to the right every once in a while (lately at least 1 per round), usually when I'm scared to go left, or I want to fade and just give it too much.

Things that I've found:

1) wrist at the top is flexed back (wrong way) at the top. You can either get a pen and put it in between your watch and your glove to make sure it's the right way, or there are a couple aids that help with this. 

2) You could be hitting it on the heel of the club, which spins it to the right. Get some grey label painters tape and put it on your club face to see where you're hitting it (great cheap and reusable impact tape-peel and reapply for next shot).

3) Could be over the top or out to in, but most better players are not, and if it's a new problem, that's probably not it. 

4) You could be swaying a lot in your swing and bringing a lot of inconsistencies...

I do a combination of 1, 2 & 4 often enough to know that it sucks... I usually do it on a hole that often gets the best of me. Watch your tempo, and make sure you get set at the top before swinging down. Also look at your swing plane--take it back slowly to the top on plane and stop. 

Hope something in here helps! 

Go see your local pro, he/she would probably be able to identify it and help you pretty quickly.

While I'm no expert, try shortening your swing to 3 and 9, check the ball flight and then slowly increase it to a normal swing.  You should be able to pick up where it's starting to go wrong.  Maybe you're rolling your wrists on takeaway and it's leaving your club face open as you get to the bottom.

For me, a sliced drive almost always means that I was lazy and slid my hips instead of turning them.  That causes the face to stay open and sliceroni.

That pen trick seems to have fixed it for now! I can't believe I have never thought of it but it turns out my wrist was flexing weird. Thanks B.A.!

Just checking this thread again...

Congrats! I'm so glad it helped!

One of the most common culprits of a slice is the dreaded "over the top" move.

The simplest way to overcome the "over the top" is to make an effort to make a fuller turn and being conscious of your right shoulder moving down before any other upper-body movement.

(**note** Turn = torso rotation around a fixed spine angle, backswing = club arc/ position at the top. Very different.)

If you notice this helps, but the ball still has a tendency to move left-to-right, there is a need for a more active forearm release. And yes, FOREARMS. Not wrists or DEFINITELY NOT HANDS.

What I did to fix my slice is I swung to the right side of the fairway really aiming to the left side. That's what helped my slice and I hope it helps your swing.

Easy drill to makesure you keep everything in-sync... pretend like you are squeezing a basketball between your knees while you hit some balls on the range.  It will prevent hip slides and early releases, which tends to be the quick fix for the problem.  Good luck and hit 'em straight!

Another hip slide killer is to tighten your core muscles like you are going to get punched in the gut. Really helps to prevent sliding and I find it helps slow down my tempo as well.

hit up the range and just imagine your club head going down the first base line after impact. also i have noticed shortening my swing and slowing down my back swing has helped.

Well I found out if I flatten my swing going back.  In other words I "try to hold the tray" with my right arm.  That makes me swing inside toward the ball.  I was at the driving range and I found out if I did that I could hit it hard as I wanted and still did not slice.  But for you I say, ask a PGA Pro and he can fix you in minutes.  

When I became more conscious of my wrist , and was able to correct that with my swing path, I was seeing a serious difference in my drives.  The clubface seems too square up nicely.   

Have fought a slice for years, Pretty much gone, but rears its ugly head on occasion.  I strengthened my grip, and a little bump of hips, not a turn, but forward bump, gets my hands in a better inside out position and allows me to swing the club to the shortstop ( i'm a lefty) and most remember to roll the forearms. Or as a buddy puts it, have my back hand slap the ball.  Good luck!

Ball flight is determined by a combination of clubbed path and face angle at impact.  The initial flight of the ball is determined by clubbed path.  If you swing outside in, the ball starts left.  Inside out, the ball starts right.  This will give you an indication of your swing path.  How the ball turns (Slice, hook) after it launches is determined by face angle at impact.  Straight club path with open face will produce a shot that starts straight, then slices.  So, take a look at your ball flight to determine what you are doing.  This should clue you in to what you need to work on.  Remember, the ball never lies.

Also, what has helped me sometime when I slice badly, or get close to the shanks, as you say, is to put the ball as far away from me as I can reach, and make sure it is off the left heel in my stance, like Moe Norman.  I find that this helps me to swing on a more inside swing path, and with the ball forward, the clubbed will either be square or slightly closing.

On your down swing, try to swing closer to your body from inside out, which usually creates a draw.

Also try to figure out if your coming too much over the top on your down swing
