I use the Dexron/Mercon in both the Ttwin-Ultra and the PS. I have NO high range clutch groan except maybe on rare occasions during cold weather below 20 dregeer F.

The trans had A LOT of high range groan when i first got the car and a few other occasional operational problems. These problems have all but disappeared by about 90% AFTER i changed to the Dexron/mercon and it took about 6 months for the groan to leave.

There is about 20K miles on the trans now with the Dexron/Mercom fluid. It works just fine.

Those of u satisfied with the type F should stay with it and not change. I doubt that it makes any difference.
