If you look at the owners manual for a late model Mustang GT with a T-5, I think they recommend every 50,000 miles.....
And most owners never changed the fluid in theirs with well in excess of 100,000 miles on their cars.......

If it makes you feel better I'd say once every 7 years is just about right!!!!!!!!
