I have spent years being a Master Mechanic for both General Motors, Ford and a shop of my own. We have been using synthetic automatic transmission fluid in both street and race cars with no significant problems. They run cooler with better lubrication! My question is... if they work well in cars automatic transmissions, why not Harleys?
