How much ATF to refill?

I m planing to change my ATF this week, but I m not sure how much to fill in? 3 qrt?
It’s great if anyone can help me with that. =)

btw, change ATF when the engine is warm or cold?

Your car has to be on level ground. Mine was changed when the engine was still warm. Make sure you refill it with Honda ATF ONLY. How much you refill depends on how much came out. I believe mine used about 5 quarts. But there’s a level on the AT dip stick that you should keep checking. You’ll have to check it while the engine is running though.
