You may need to change your transition. What I like to feel is that I stand on my left foot (you could also feel it like push your left foot into the ground) and then a split second later swing hard to the left (around myself). Im right handed obviously

Do this in slow motion and you'll see this standing action transfers your weight and drops the club on plane (the slot some call it .. i hate that phrase!). From there you can swing hard left and around yourself

If you can get to the range , try and hit about 50 balls this way starting with a PW. It will feel really strange to start with and you may block right or push as you wont be used to the swinging around yourself motion or the timing but stick at it and see how you go
