5. If the level is below the lower
mark, remove the fill plug, then
add the fluid into the hole to bring
it to the level between the upper
and lower marks.
Pour the fluid slowly and carefully so
you do not spill any. Clean up any
spill immediately; it could damage
components in the engine
compartment.
Always use Honda ATF-Z1
(automatic transmission fluid). If it's
not available, you may use a
DEXRON III automatic
transmission fluid as a temporary
replacement. However, continued
use can affect the shift quality. Have
the transmission flushed and refilled
with Honda ATF-Z1 by your dealer
as soon as it is convenient.
