I had the idea of making a fully working and operateable transmission. This is still a work in progress. I'm working on adding reverse. ***I fixed the clutch, altho im am un sure of any errors but it work perfectly fine as long as u follow instructions. It is based off a car transmission. to operate click play and pause right away. set all the sliders to zero. click play again an drive it like shift. let off gas pull clutch switch gears unpull clutch then give gas. Credits to Cphillips for the development of sketchyphysics an averything else was created by me.
