Keep in mind that solenoids are one-directional, and their "rated" force exists only in a small fraction of their total stroke.

Why should it be 60 PSI? Shouldn't it be closer to the actual force required?

Our own shifters we had, we've always run at 20 PSI for the solenoid valves sake. I was under the assumption that it took less force than the 12 lbs to shift but I could be wrong about this as I have no experience with the super shifters.
