Nice job, but the high frequency positive pressure differential doesn't seem to actuate the dual-quad bilateral quantitation reflexing circuit. Maybe a second-order translation relaxation amplifier in-line with the flux-capacitor will reduce that jitter. Thoughts?

the main winding should be of the normal lotus-o-delta type placed in panendermic semi-boloid slots in the stator, every seventh conductor being connected by nonreversible trem'e pipe to the differential girdlespring on the 'up' end of the grammeters.

also, I think you messed up on the collision layers

All gibberish aside (it was in good fun), I posted a scene response that fixes the problem with the jittering gear shifter. I hope it's useful to you.
