How often do you have your Allison 6 speed transmission serviced?

We have 03 and did not having any maintenance records. So we felt like the transynd was worth the $500. I don't have the paper work in front of me but I believe it the fluid itself is good for 50,000 to 75,000 miles and the filters should be changed every 3 yrs.
