For the opening differential and the thunbnail- Mira invented this type of piston differential, Conun merely rebuilt it and made it a bit easier to see. I merely fixed the cyan motor and the labels.
All the others were made by me. Credit to Kilinich and Conundrumer for the C-gears.

This is probably the most innovative differential I have ever seen.
And I reverse-engineered it only from Conun's version.

Now, to make it into a fully-functioning transmission!
