I am sorry that Team 2234 has had these problems.
The transmission failure you describe sounds to me like something was wrong with the transmission from the start. Teams should not have had to file burrs off of gears to get them to run. The "lock up" seems to me like it must be one of the flat washers getting eaten by the gears or else some metal shavings in the mix somehow or that it was re-assembled improperly.
I have analyzed the gear teeth loading as well as the brass material that they are made from. Do not think that brass = soft. Brass comes in many varieties. This particular brass is harder than the steel gears that they mesh with. Believe me they do not "wear down almost immediately" not unless something other issue is at play.
This is more of an infant mortality issue and a quality control issue. While this is bad, I am not as worried about these types of failures because teams discover them early and have a chance to fix them. The D joint failure is one that seems ok but breaks in a match -- much worse.
I am not recommending that teams pitch the entire 56mm transmission. I believe the system is quite workable. I remain confident that this problem will have a happy ending. There are a number of people looking into the issue and working to find a way of addressing the issues found.
