If the level is below the lower
5.
mark, add fluid into the filler hole
to bring it to the upper mark.
Pour the fluid slowly and carefully
so you do not spill. Clean up any
spills immediately. Spilled fluid
could damage components in the
engine compartment.
Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it is not available, you may use a
DEXRON III automatic
transmission fluid as a temporary
replacement. However, continued
use can affect shift quality. Have
the transmission flushed and
refilled with Honda ATF-Z1 as
soon as it is convenient.
To thoroughly flush the transmission,
the technician should drain and refill
it with Honda ATF-Z1, then drive the
vehicle a short distance. Do this
three times. Then drain and refill the
transmission a final time.
6. Insert the dipstick all the way back
into the transmission securely as
shown in the illustration. If you
added fluid, return to step 1 to
recheck the fluid level.
Transmission Fluid
The transmission should be drained
and refilled with new fluid according
to the time and distance recommen-
dations in the maintenance schedule.
If you are not sure how to add fluid,
contact your Honda dealer.
