Help identifying valvebody?

In figure #6 you can see that the arm of the kd shaft has been cut off. That means that the kd shaft will just spin and not activate a valve. And the op's is most likely as the pic. But what if it isn't? The complaint is a soft shift. Why is there a soft shift? Did somebody modify this valve body? I don't care how things come from factories because I've seen too many transmissions assembled too many crazy ways. So: the story will end when the problem is solved; not before.
