I'm opening up the CAD so I can see what happens when you slow down.
EDIT: yup, the dog bounces back and forth like crazy while rubbing against the shifting elements when you slow down, which would completely destroy the teeth on the mating elements. I'm going to find a solution to that.
DOUBLEEDIT: So what would happen is this:
1. The dog slows.
2. The dog is pushed into the other gear by the obtusely angled faces.
3. The obtusely angled face there pushed the dog back.
4. Repeat steps 2-3 until the dog contacts the flat of the teeth and cannot shift out of its current gear.
5. The gear that it is in is forced to slow down slightly until the dog bounced back into the other gear.
Repeat until slowed. There would be a lot of bouncing, but nothing too high load except for the rubbing at the end. Another thing to test under load, although this is a much more serious issue.
Of course, that doesn't matter if you are doing something at a constant 100% speed like loading a spring or climbing, but for drive this seems like a problem.
