6 Speed Allison Automatic Transmission

This model is base on the Allison 1000 automatic transmission. Is not an exact replica, but the basic design and functionality is the same. The most significant difference from the real transmission is the C1 and C2 clutches that I design to work with 3D printed parts and for easy engagement.   Assembly video: https://www.youtube.com/watch?v=vvhICaIRjOY   Gear ratios: 1st: 3.202nd: 1.863rd: 1.434th: 15th: 0.706th: 0.60R: 4.41 I made the lower part of the case quite big so there is room for optionally put solenoids to engage all the clutches and even a parking pawl. If you are interested on this you should print all the "Solenoid Version" parts. This will allow you to engage the clutches more easily with switches, or even change gears automatically with something like Arduino. There is also an adapter to fit this transmission to the Toyota 4 Cylinder 22RE Engine made by ericthepoolboy.
