12yearhondatech,
Can I re-fill the fluid through the dipstick? As JimBlake mentioned, I can fill the automatic tranny fluid through the dipstick. Is it right that removing the filler plug is to ensure it is not overfilled? I am not really concerned about over-filling the tranny since I will do it slowly and refilling with the same, a little more or less, amount I drained.

Thank you very much for your all info.
