If this does wind up being a Thursday fix at the regionals, teams should prepare by making sure that they have a process for getting out the gearboxes. Something to press the pins out will be useful too...a table top drill press can probably work. And don't rush the job...it's better to spend an hour or two making sure the alignment is good and the gearboxes are broken in than to find out on Saturday that you have nothing but rounded off brass cylinders where your planets used to be.
That being said, if you are a team using 12:1, 1 CIM (like many rookies, I'd imagine), have been driving around for a while and haven't notice any major backlash problems, and have taken appropriate software measures to reduce shock loading, would you still repair these on Thursday at a regional? I'm not sure that I would.
