Weird Behavior - Vex Pro Ball Shifters

[Nunners]

Gearbox is functioning as it should now. We opened up our gearbox and made sure that the cylinder was pushing and pulling at the correct distance. Also, we fabricated some more exact spacers to input onto the hex shaft where our wrench is mounted. It seems like both of these modifications fixed the problem.

Even without applying any PSI, the shifter is no longer pulled into the gearbox.

Thanks for all of the suggestions!
