+1 on other teams being super helpful. We coasted our car into the pits with a broken shifter clip (which lives right next to the surface-of-the-sun hot exhaust pipe). While we were trying to figure out what on earth to do, another team volunteered that they had just done theirs recently, dove in, yanked the old part, tossed the still burning hot part to a teammate who welded it back together, and slapped it back in the car, in under 10 minutes. It felt like a NASCAR pit stop.
