2004 HONDA ODYSSEY Transmission

You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal
and it is the proper weight. You must
f ollow the oil and f ilter change
intervals given on the maintenance
schedule.
Your Honda does not require any oil
additives. Additives may adversely
af f ect your engine’s or transmission’s
perf ormance and durability.Always change the oil and f ilter
according to the recommendations in
the maintenance schedule. The oil
and f ilter collect contaminants that
can damage your engine if they are
not removed regularly.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
mechanic.
Run the engine until it reaches
normal operating temperature,
then shut it off. Open the hood and remove the
engine oil f ill cap. Remove the oil
drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.

Check the f luid level with the engine
at normal operating temperature.Park the vehicle on level ground.
Shut of f the engine.
Remove the dipstick (yellow loop)
f rom the transmission, and wipe it
with a clean cloth.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them. Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather. The low washer
level indicator will come on when the
level is low (see page ). Check the reservoir’s f luid level by
removing the cap and looking at the
level gauge attached to the cap. Check the f luid level in the
windshield washer reservoir at least
monthly during normal use. This
reservoir supplies the windshield and
rear window washers. 1.

Do not use engine antif reeze
or a vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

To thoroughly f lush the transmission,
the technician should drain and ref ill
it with Honda ATF-Z1, then drive the
vehicle f or a short distance. Do this
three times. Then drain and ref ill the
transmission a final time.Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
If you are not sure how to add f luid,
contact your Honda dealer.
If the level is below the lower
mark, remove the f ill plug and add
f luid to bring it to the upper mark.
Pour the f luid slowly and caref ully
so you do not spill. Clean up any
spills 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 f luid as a temporary
replacement. However, continued
use can af f ect the shif t quality.
Have the transmission f lushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.
Insert the dipstick all the way into
the transmission as shown.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks. 5.

If you need to park your vehicle f or
an extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.Fill the f uel tank.
Change the engine oil and f ilter.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc. are
completely dry.
Leave the parking brake off. Put
the transmission in Park. Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and tailgate seals.Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
If you store your vehicle f or 1 year or
longer, have your Honda dealer
perf orm the inspections called f or in
the 2 years/30,000 miles (48,000 km)
maintenance schedule (Normal
Conditions) as soon as you take it
out of storage (see page ). The
replacements called f or in the
maintenance schedule are not
needed unless the vehicle has
actually reached that time or mileage. 205

Diagnosing why your engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
When you turn the ignition switch to
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things: Check the transmission interlock.
The transmission must be in Park
orNeutralorthestarterwillnot
operate.
Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlights
are very dim or don’t light at all,
the battery is discharged. See
on page .
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereis
probably something wrong with
the electrical circuit f or the
ignition switch or starter motor.
You will need a qualif ied
technician to determine the
problem (see
on page ). If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of the
battery and terminal connections
(see page ). You can then try
jump starting the vehicle from a
booster battery (see page ).
In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.

procedure? Ref er to on page .

Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).
Do you have f uel? Check the f uel
gauge; the low f uel indicator may
not be working.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page . Although this seems like a simple
procedure, you should take several
precautions.
You cannot start a Honda by pushing
or pulling it.
Connect one jumper cable to the
positive ( ) terminal on your
Honda’s battery. Connect the
other end to the positive ( )
terminal on the booster battery. Put the transmission in Neutral or
Park, and set the parking brake. Turn of f all the electrical acces-
sories: heater, A/C, climate
control, audio system, lights, etc. Open the hood and check the
physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or like ice, do not try
jump starting until it thaws.

NOTICE:
A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery. If a battery sits in extreme
cold, the electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

The pointer of your vehicle’s
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If your vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park, and set the parking brake.
Turn of f all accessories, and turn
on the hazard warning indicators.
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
If the temperature gauge stays at
the red mark, turn of f the engine.
