for a 4spd tranny but could be adapted for 5/6spd with another cam. The select on the bmw transmissions is different though so the only part of that design that applies is the cam, and even the cam would need to generate motion in 2 axis.
I definitely want to design and build one of these for a 4th year engineering project if I can get it approved (buy an old getrag to prototype on, then retrofit to a car with the same transmission). I would definitely try to incorporate the ability to grab neutral at any time though. |
I would be willing to donate a tranny for you to prototype on  aslong as i get it back for cheap when its done lol
