I joined this forum just to add a link for the pin itself. I have no room to work on my car, so I'd rather pay my mechanic (a good guy) for his labor than shell out ~$550 for an entire shifter assembly that is otherwise working perfectly. Sure, this spring is probably just as thin and will break again in a few years (our mini is a 2016 w/ just over 42k miles), but you all sent me in the right direction with videos and information (so I'll know how to change it myself when I live somewhere with a garage/driveway), so if I can help you out and save you money, that's good enough for me.
