I had no forewarning or anything. Just a truck, a uniformed guy standing there asking if I’m Ash. Thankfully the exchange went smoothly, but I’ve got my work cut out for me in the coming days.

Apparently most Honda trannies only allow about 1/4 of the ATF to be drained at a time, so the change process is a progressive dilution over multiple maintenance events. At least it’s DIY so I can just space it out at my convenience.

The pic at the top is what happens when you don’t change you Honda ATF for 100k miles.
