The transmission is back from being "undercut." This process modifies the gear engagement dogs so that with driving force on them, they "lock" together via machined ramps on the dogs. If you look closely at the bottom right gear you can see the angled ramps. The result is the transmission will not slip out of gear with a load on it.
