Sorry for the 3 year delayed response! I'm just seeing your comment now for some reason. No it has not been fixed. It's been gradually getting worse and now the tractor has about 1000 hours on it. I can still do everything I need to do with the tractor so I decided to put off the repair until it gets really bad. I was planning on doing the rockshaft seals first and if that didn't work I was going to replace the three point control valve. I'm going to have to do the work myself because my local LS dealer dropped LS and there isn't one nearby. I'm not a good mechanic so I'm hoping to watch some youtube videos. I do have the service manual. Overall the tractor has been good (minus this issue). I will update this thread when I decide to take on this repair. I did notice the control valve itself is now selling for over $400 so maybe I should have bought it 4 years ago!

You previously stated that if you screwed in the drop speed valve all the way to the lock position, the hitch no longer settled. This tells you that the oil is not bypassing the seals in the rockshaft cylinder and has to be going out through the hitch valve. If the rockshaft cylinder seals were leaking, closing the drop speed valve would make no difference and the hitch would still settle. Closing the drop speed valve to lock position stops oil from going out through the hitch valve so the problem has to be in the hitch valve. There are a couple of spools that can stick and a check valve that can leak. You can try to fix it, but most likely it will need to be replaced. There is an adjustment on the spools, but it doesn't get out of adjustment by itself so trying to adjust it probably won't fix it.
