You are ok, to (gravity/dilute) change it at 90,000 miles.
Do not let someone talk you into a power flush, because Acura/Honda trans are low pressure units and will be screwed, if you force fluid into them.
If you are concerned, about the miles on the trans, then only do 1 gravity bleed trans/fluid (dilution) change every oil change for the next year.
The torque spec for the trans/fluid nut is 36 ft/lbs. It's aluminum and it will strip.
If you do decide to do 3 or 4 gravity bleeds, within a week or two (or even the same day), you do not have to replace the washer, until the final bleed.
After each bleed:
1. Drive it easy
2. Get the speed up to about 42 mph, or when the crusing (economy) gear kicks in. Do this twice.
3. Go to a parking lot and back it up for about 50 feet.
Now the new fluid is mixed with the old.
You can now do a 2nd bleed, or you can wait, until you feel like crawling under the car again.
