AUTOMATIC TRANSMISSION AND DIFFERENTIAL
cold, the level should be found
below the center of these two
marks.
NOTE:
a. Use care not to exceed the upper
limit level shown in item 2) below.
b. Check the ATF level when deliver·
ing a car to a customer.
2) ATF level
a. ATF level varies with temperature
as shown in figure. Remember that
the addition of fluid to the upper
limit mark when the transmission is
cold will result in the overfilling of
fluid.
b. Fluid temperature rising speed,
• By idling the engine /
Time for rising temperature to
60°C (140°F) with atmospheric
temperature of O°C (32°F): More
than 25 minutes
(Reference)
Time for temperature rise to 30°C
(86°F) with atmospheric temperature
of O°C (32°F): Approx. 8 minutes
• By running the vehicle
Time for temperature rise to 60°C
(140°F) with atmospheric tempera-
ture of O°C (32°F): More than 10
minutes
c. Method for checking fluid level
upon delivery or at periodic inspec-
tion.
Check fluid level after a warm-up
run of approx. 10 minutes. During
this warm·up period, the automatic
transmission functions can also be
checked.

4) Replacement of ATF
a. After allowing the engine to cool
for 3 to 4 hours, remove the fluid
pan drain plug, and drain oil
thoroughly.
NOTE:
a. The fluid will be discharged to the
front as the drain plug is removed.
To avoid the stream of fluid, the
worker should stand under the oil
pan toward the front of the car
performing this procedure.
b. The amount of fluid that can be
drained is approx.
4Q
(4.2 US qt,
3.5 Imp qt) of the total capacity of
6.0 to 6.4
Q
(6.3 to 6.8 US qt, 5.3
to 5.6 Imp qt) for 4WD and 5.6 to
6.0
Q
(5.9 to 6.3 US qt, 4.9 to 5.3
Imp qt) for non-4WD. Some fluid
will remain in the torque converter,
oil passage, or in the valve body.
b. Tighten the drain plug. [Tightening
torque: 25 N'm (2.5 kg·m, 18 ft-
lb )].
NOTE:
Be sure to replace the gasket with a
new one.
c. Pour 4Q (4.2 US qt, 3.5 Imp qt) of
recommend~d
ATF into the case
through the oil supply pipe.
d. Run the vehicle until the fluid
temperature rises to 60 to 80°C
(140 to 176°F), and then add fluid
7-31
until the oil level can be found
within the specified range.
NOTE:
a. If the drained fluid is black or
thick, it indicates that some com·
ponents in the transmission are
faulty. Disassemble and check the
transmission.
b. Be sure to use recommended ATF
when changing the transmission
fluid.
2) Differential gear oil
• Checking oil level
1) Ensure the vehicle is level.
NOTE:
Do not check the oil level nor add oil
to the case with the front end of the
vehicle jacked up; this will result in an
incorrect reading of the oil level.
2) Check whether the oil level is
between the upper and lower marks.
If it is below the lower limit mark, add
oil until the level reaches the upper
mark. The difference in level between
upper and lower marks corresponds
to 0.4Q (0.8 US pt, 0.7 Imp pt).
