Jatco, (the manufacturer of our RE5R05A), recommends that you never need to change the Titan's transmission fluid.
"Q. How often should the oil be changed in automatic transmissions?
A. Our products basically do not require oil changes. There are CVTs, however, that signal the need for an oil change and you should therefore check the handling manual of your vehicle for details." http://www.jatco.co.jp/ENGLISH/PRODUCTS/at_qa.html

Nissan is telling the dealers not to machine flush our transmissions. Check out this TSB (in .pdf format), a member over at CT posted:
