Modifying Vexpro Ball Shifter transmissions

Any suggestions?

How did you lose air? (I'm assuming you made a type when you said "loose".) If it was through a problem with your pneumatics system, it may be more important to secure the whole system rather than trying to rig the shifters to default to one position. (Personally, I see the default neutral as a feature, not a bug, and I wonder if 1678 might be able to take advantage of it in the future...)

Our team ran with the ballshifters last year, and though we occasionally had pneumatics leaks elsewhere in the system, the gearboxes themselves didn't present any issues in that regard. If it really concerns you, I'm sure you can rig some springs to the cylinder-pin coupler.
