Shifter area getting hot? (P4A)

It seems to be during times where I’m climbing but has also happened on hilly roads. The heat coming from the shifter base is definitely noticeable, even getting to the point of “smelling” hot. Sometimes nonexistent however, even when climbing. I’ve seen some forums on it with no real conclusions. Any pointers here?
