Someone with a wrench and access to the gear box is soon to find out.
I don't know what the internals of this particular gear box can handle, but I have seen some that have been internally pulverized and usually it's just been a bunch of teeth shattered off the gears and the input pinion giving itself a shave against the sharp remainder of the downstream gear that it no longer properly engages with while inertia has kept the big parts rotating and circulating the fragments to do more damage until the last of the momentum is turned to metal chips.
On an internal driven gear one of the internal gear teeth snapped off and got embedded in the pinion; all the other pinion teeth were fine, but in the exact gear ratio it looked like someone took a sledge hammer and bashed out little sectors of the internal gear. People oohed and ahhed over the amount of damage but the system was finished off by a little sliver of metal that snapped off the ring gear. Everything else broken was just decoration. That was for a TF/TA radar system that no one could tell us what it was for, but sometimes the planes came back with chlorophyll stains on the wing tips.
