ON-VEHICLE SERVICE

ESSENTIAL SERVICE

AUTOMATIC TRANSMISSION FLUID CHECK

Caution
When the transmission has been replaced or overhauled,
or driving has been carried out under the severe condition,
the A/T fluid cooler line flushing should always be carried
out and also, the A/T fluid and oil filters (special filters for
transmission only) should always be replaced.

1.

Drive the vehicle until the fluid temperature rises to the
normal temperature (70 – 80



C).

NOTE
1) Measure ATF temperature using MUT-II.
2) Check the oil level referring to the characteristics chart

shown at left if it takes some time to reach the normal
operation temperature of ATF (70 – 80



C).

2.

Park the vehicle on a level surface.

3.

Move the selector lever through all positions to fill the
torque converter and the hydraulic circuits with fluid, and
then move the selector lever to the N position.

4.

After wiping off any dirt around the oil level gauge, remove
the oil level gauge and check the condition of the fluid.

NOTE
If the fluid smells as if it is burning, it means that the
fluid has been contaminated by the particles from the
bushes and friction materials, a transmission overhaul and
flushing the cooler line may be necessary.

5.

Check that the fluid level is at the HOT mark on the oil
level gauge. If the fluid level is lower than this, pour in
more fluid until the level reaches the HOT mark.

Automatic transmission fluid:

Dia Queen ATF SP 

II

  M

, 

ATF SP 

III

 or equivalent

NOTE
If the fluid level is low, the oil pump will draw in air along
with the fluid, which will cause bubbles to form inside
the hydraulic circuit. This will in turn cause the hydraulic
pressure to drop, which will result in late shifting and
slipping of the clutches and brakes.
If there is too much fluid, the gears can churn it up into
foam and cause the same conditions that can occur with
low fluid levels.
In either case, air bubbles can cause overheating and
oxidation of the fluid which can interfere with normal valve,
clutch, and brake operation. Foaming can also result in
fluid escaping from the transmission vent, in which case
it may be mistaken for a leak.

6.

Securely insert the oil level gauge.

AUTOMATIC TRANSMISSION FLUID REPLACEMENT

Caution
When the transmission has been replaced or overhauled,
the transmission fluid cooler line flushing should always
be carried out before installing the transmission fluid
cooler hose.

If you have a fluid changer, use this changer to replace the
fluid. If you do not have a fluid changer, replace the fluid
by the following procedure.
1.

Disconnect the hose shown in the illustration which
connects the transmission and the oil cooler (inside the
radiator).

2.

Start the engine and let the fluid drain out.

Running conditions: N range with engine idling

Caution
The engine should be stopped within one minute after
it is started. If the fluid has all drained out before
then, the engine should be stopped at that point.

Discharge volume: Approx. 3.5 L

3.

Remove the drain plug from the bottom of the transmission
case to drain the fluid.

Discharge volume: Approx. 2.0 L

4.

Replace the oil filters. (Refer to P.23-44.)

5.

Install the drain plug via a new gasket, and tighten it to
the specified torque.

Tightening torque: 32 Nm

6.

Pour the new fluid in through the oil filler tube.

Adding volume: Approx. 5.5 L

Caution
Stop pouring if the full volume of fluid cannot be
poured in.

7.

Repeat the procedure in step 2.

NOTE
Drain the fluid from the cooler hose 7 L at least. Then
drain the fluid a little and check the fluid for dirt. 
If it has been contaminated, repeat the steps 6 and 7.

8.

Pour the new fluid in through the oil filler tube.

Adding volume: Approx. 3.5 L
