Remove the dipstick, and refill the transmission with the recommended fluid amount through the opening of the dipstick guide pipe until the level reaches between the upper mark and the lower mark on the dipstick. Always use Acura ATF-Z1 automatic transmission fluid (ATF). Using a non-Acura ATF can affect shift quality.
