It sure is. I'm not sure how much smoother it shifts with Rotella since that's all I've put in it since draining the break in oil at 600 miles. The clunk it had with the break in oil almost completely disappeared when I drained it and put rotella in. I knew it would be better, but not as good as it is. I talked my dad into trying it in his ultra glide, and he loves it. He had problems getting it into neutral running Harley oil, but it falls right it with rotella. I love this stuff.
