Usually I am not big into posting videos for people to watch, but I think this video of the allison and how it shifts gears was pretty interesting. 16 minutes long, nothing fancy, but I learned a good bit from it, such as which clutches were associated with which gear. Hope everyone else finds it as useful as I did and can use this information to better your tuning!
