I'm not sure what you meant about filing down the bad thread, but
there are thread files made for cleaning up threads. They are a lot
cheaper than large dies and all you have to match is the pitch, not
the diameter. I guess step one is to pull the transmission as you
have to do that anyway. If you can see damaged threads, then hitting
them with a thread file seems like a reasonable idea. The couple of
week scenario doesn't sound too pleasant.
