CG in Games

So my Countryman threw a gearbox warning light yesterday along with a message telling me to drive carefully. The car still moves and shifts but feels a bit hesitant now, and I am not sure if I should keep driving it or park it until I get it looked at. I do not want to make things worse by being stubborn about it. I have been looking for information and someone suggested I visit this page for Mini Cooper transmission service to understand what the warning might mean, but I would rather hear from owners who have actually seen this light. Did yours turn out to be something minor or did it need serious work? Also is it generally okay to drive short distances to a workshop or is that risky with these gearboxes? I have a busy week and I am trying to figure out the logistics without causing more damage.
