1. Remove the hose shown in the illustration which
allows the A/T fluid to flow from the A/T fluid
cooler (built into the radiator) to the transmission.
CAUTION
The engine should be stopped within one minute
of it being started. If the A/T fluid has all been
discharged before this, stop the engine at that
point.
2. Start the engine and discharge the A/T fluid.
Driving conditions: N range, idling
Discharge amount: Approx. 3.5 L
3. Remove the drain plug at the bottom of the
transmission case to drain out the remaining A/T
fluid.
Discharge amount: Approx. 2.0 L
4. Install the drain plug with a gasket in between,
and tighten it to the specified torque.
Tightening torque: 32
± 2 N⋅m
CAUTION
Stop pouring in the A/T fluid once 5.5 L has been
poured in.
5. Pour in new A/T fluid through the oil filler tube.
Amount to add: Approx. 5.5 L
6. Repeat the operation in step 2.
7. Pour in new A/T fluid through the oil filler tube.
Amount to add: Approx. 3.5 L
NOTE: Carry out steps 2 and 7 so that at least 8.0
L has been discharged from the cooler hose. After
this, discharge a small quantity of A/T fluid and
check for contamination. If the A/T fluid is
contaminated, repeat steps 6 and 7.
8. Connect the hose which was disconnected in step
1, and then securely re-insert the oil level gauge.
9. Start the engine, and let it run at idle for 1
− 2
minutes.
10.Move the selector lever to all positions once, and
then return it to the N position.
11.Check that the A/T fluid level on the oil level
gauge is at the COLD mark. if it is not up to this
mark, add more A/T fluid.
12.Drive the vehicle until the A/T Fluid temperature
reaches the normal temperature (70
− 80°C), and
then re check the A/T fluid level.
NOTE: The COLD mark is for reference only; the
HOT marks should be used as the standard for
judgment.
NOTE: A/T fluid temperature using MUT-III.

NOTE:
Check the oil level referring to the characteristics
chart shown at left if it takes some time until
reaching the normal operation temperature of A/T
fluid (70
−
80
°
C.)
13.When A/T fluid is under the specified level, top up
A/T fluid. When A/T fluid is over the specified
level, drain the excessive A/T fluid from the drain
plug to adjust A/T fluid level to the specified level.
14.Securely insert the oil level gauge into the oil filler
tube.

CAUTION
If replacing the transmission with a new one, if
overhauling the existing transmission, or if the
A/T fluid has deteriorated or is contaminated, the
A/T fluid cooler line must always be flushed out.
1. Remove the hose shown in the illustration which
allows the A/T fluid to flow from the A/T fluid
cooler (built into the radiator) to the transmission.
CAUTION
The engine should be stopped within one minute
of it being started. If the A/T fluid has all been
discharged before this, stop the engine at that
point.
2. Start the engine and discharge the A/T fluid.
Driving conditions: N range, idling
Discharge amount: Approx. 3.5 L
CAUTION
Stop pouring in the A/T fluid once 3.5 L has been
poured in.
3. Pour in new A/T fluid through the oil filler tube.
Amount to add: Approx. 3.5 L
4. Repeat the operation in step 2 and 3.
NOTE: Carry out steps 2 and 3 so that at least 8.0
L has been discharged from the cooler hose. After
this, discharge a small quantity of A/T fluid and
check for contamination. If the A/T fluid is
contaminated, repeat steps 2 and 3.
5. Carry out the procedure in "Automatic
Transmission Fluid (ATF) Replacement" from step
2 onwards.

2. Loosen the adjusting nut, and set the manual
control lever upper and lower to the free condition.
3. Move the manual control lever lower to the neutral
position.
4. Loosen the inhibitor switch body mounting bolts,
and then turn the inhibitor switch body to align the
second hole from the end of the manual control
lever with the hole in the inhibitor switch body
flange (section A
− A).
NOTE: The inhibitor switch body can be aligned
by hand, because the manual control lever end is
as wide as the switch body flange. Alternatively,
the inhibitor switch can also be aligned by
inserting a 5-mm bar in the second hole from the
end of the manual control lever and the hole in the
inhibitor switch body flange.
CAUTION
Be careful not let the inhibitor switch body slip
out of place.
5. Tighten the inhibitor switch body mounting bolt to
the specified torque.
Tightening torque: 11
± 1 N⋅m
6. Tighten the transmission control cable locking nut
to the specified torque.
Tightening torque: 12
± 2 N⋅m
7. Check that the selector lever is at the N position.
8. Check that the transmission shifts to the correct
range corresponding to the position of the selector
lever, and that it functions correctly in that range.
