Then do the Bench drill:

Either find a bench that has a low back or no back, or have a buddy stand behind you with driver grip pointing at the target and level around the middle of the knees and waist.

Rest your club at setup above the bench (standing so the long side of the bench points at your target) or buddies club.

Use the 1 piece takeaway with your shoulders back slowly. Your club will be sliding down the bench or shaft the whole way if done correctly. If your club leaves the bench or shaft, you are probably lifting too soon with the hands. If you start to press down on the bench or shaft too much, you are probably using your arms to take the club back.

It is truly the perfect drill for what you are talking about. Your shaft should simply slide easily down the bench and when it gets to the end, you are ready to start setting the hands and raise the arms.
