IMO, regardless of cost, I feel that anything that's not needed is a 100% waste of money. It's like buying something, anything on sale that you just don't need.
I'm with you. I've run the FF AF to the time for the Honda TB/water pump service, then subsequent 50-60k. And, I've only ever done 'single' ATF d&f's at ~25-30k intervals on the Honda's I maintain.
The 01 Civic went to 60k on the FF ATF, now that was before I joined bitog so I might have shortened that up to 25-30k miles as I've done on my Accord. But, check the 01 Civic AT on car compliants.com and now with ~210k on original AT and still shifting fine (knock wood). And the greater heresy may be using Maxlife and even some Castrol IMV after Z1 superseded.
That said if I had to pick, imo the trans service d&f's are significantly more important than more frequent than recommended AF d&f service.
