If you take a look in the CAD model, the plunger that forces the balls into the inside of the gear is sort of wedge-shaped. If you didn't extend it fully, it might be gripping the gear a bit with friction that later slips under a more aggressive ball load. This may explain why adding pressure helps a bit but doesn't solve the problem (more force, more friction).
We are also using a ball shifter in a ratcheting winch - as a caution, we had issues getting the gearbox to shift into neutral under load with the stock pneumatic piston.
For getting the shifter to shift into neutral this year we used 2 of the ball shifters in parallel and they provide enough force to shift to neutral while the winch is under load
Hope this helps.

This is SUPER CRITICAL!!! We tried to use ball shifters last year to use our drive motors to climb up the tower, However we were less than 1/16 out on our dimensions which resulted in the shifters clicking to neutral every time there was a load applied.
