As the owner of a transmission shop, and 4 VX's, my husband says do NOT do ANYTHING with your fluid if you aren't having any issues. The filter can be changed after 100,000 but do not flush! Just our 2 cents...
And I am not an expert so a shop owner is probably better equipped to handle this question.
Not sure how you would change the filter without losing most of the fluid anyhow.
