You have mentioned some symptoms.. but no amount of adjusting at those places you assumed would affect those symptoms will have any affect if the problem lies in varnish build up in the auto trans valve body...
If you are sure your fluid is clean,the right amount installed , the valve body holes are clean ( have used the Trans-X) and you have a new filter installed THEN you have a good chance of adjusting and tweaking by the items you were focusing on.. but not until then...
It is cheap, like under twenty bucks if you use two cans as it may suggest for your amount of fluid... and is easy to do... and many on this site , including me, have had dramatic immediate results... so little risked... and potentially much to gain...
