my step father just boght an '02 with a 47RE and i was wondering what would be some good upgrades for him to keep the tranny alive and well he uses it mostly for a daily driver and isnt interested in heavy fueling or power above stock levels. he occasionaly hauls 2000lbs in wood pellets and a 500lb snowmobile but no heavy towing outside of that. any opinions would be great!!

 

Leave it be, from description, he is adequatelly protected by routine service.

 

A very good answer at that!
