As far as I know the shaft does not come out unless the trans is taken apart. We fished out the seal peaces with a fine pick (dentist tool) being very careful not to damage the seal housing. We then cleaned the area and pressed in the seal and remounted the mode switch and performed the trans. fluid check procedure per the shop manual. I believe the dealer charges 1.5 hours of labor to replace it if it becomes an issue. The part was about 6 bucks.
