Feel free to believe and maintain AT as you prefer, certainly the right thing to do based on your beliefs. Agreed, no fluid lasts forever, nor does any vehicle or vehicle component. Hondas creative editing to make their car appear to cost less back when, oil change intervals, brake fluid change intervals, coolant change intervals not applicable to ATF discussion.
Again, I'd recommend you do what makes you feel good and based on your beliefs.
In case some of you don't visit CX-9 forums, HEREis an interesting thread...
