I have found that riding at highway speeds on hot days even affects my Shadow which I thought was built for such riding. It affects the shifting. It really needs an oil cooler or at least some cooling fins on the lower case. I haven't read other complaints, so I think it is peculiar to my bike. I am thinking that a spring in the tranny weakens when the oil is very hot because it goes back to normal after cooling just a couple minutes. No leaks though.
