INSPECTION AND CHANGE
1) Before changing or inspecting oil, be sure to stop engine and lift
vehicle horizontally.
2) With vehicle lifted up, check oil level and leakage. If leakage ex-
ists, correct or repair it.
3) Drain old oil and fill new specified oil as shown below by speci-
fied amount (roughly up to level hole).
NOTE:

It is highly recommended to use SAE 75W-90 gear oil.

Whenever vehicle is hoisted for any other service work
than oil change, also be sure to check for oil leakage and
status of breather hoses.

If water or rust is mixed in drained oil, be sure to check
breather hose and boot of transmission and transfer.

LINE PRESSURE TEST
Purpose of this test is to check operating conditions of each part by
measuring fluid pressure in fluid pressure line. Line pressure test
requires following conditions.

Automatic fluid is at normal operating temperature (70 to 80C /
158 ± 176F).

Fluid is filled to proper level (between FULL HOT and LOW HOT
on dipstick).
1) Apply parking brake securely and place checks against wheels.
2) Attach oil pressure gauge to fluid pressure check hole in trans-
mission case.
Special Tool
(A): 09925-37810
CAUTION:
After attaching oil pressure gauge, check that not fluid
leakage exists.
3) Depress foot brake fully, run engine at idle and stall and then
check fluid pressure in ªDº or ªRº range.
CAUTION:
Do not continue running engine at stall speed longer than
5 seconds.

STALL TEST
This test is to check overall performance of automatic transmission
and engine by measuring stall speed at ªDº and ªRº ranges. Be sure
to perform this test only when transmission fluid is at normal operat-
ing temperature and its level is between FULL and LOW marks.
CAUTION:

Do not run engine at stall more than 5 seconds continu-
ously, for fluid temperature may rise excessively high.

After performing stall test, be sure to leave engine running
at idle for longer than 30 seconds before another stall test.
1) Apply parking brake and block wheels.
2) Install tachometer.
3) Start engine with select lever shifted to ªPº.
4) Depress brake pedal fully.
5) Shift select lever to ªDº and depress accelerator pedal fully while
watching tachometer. Read engine rpm quickly when it has be-
come constant (stall speed).
6) Release accelerator pedal immediately after stall speed is
checked.
7) In the same way, check stall speed in ªRº range.

LEVEL CHECK AT ROOM TEMPERATURE
The fluid level check at room temperature performed after repair or
fluid change before test driving is just preparation for level check of
normal operating temperature. The checking procedure itself is the
same as that described previously. If the fluid level is between FULL
COLD and LOW COLD, proceed to test drive. And when the fluid
temperature has reached the normal operating temperature, check
fluid level again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) With engine is cool, remove drain plug from oil pan and drain A / T
fluid.
3) Install drain plug.

ON-VEHICLE SERVICE
MAINTENANCE SERVICE
NOTE:

When having driven through water, check immediately if wa-
ter has entered (if so, oil is cloudy). Water mixed oil must be
changed at once.

Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status
of breather hoses.
Gear Oil Change
NOTE:

Hypoid gear oil must be used for differential.

It is highly recommended to use SAE 80W ± 90 viscosity.
1) Before oil change or inspection, be sure to stop engine and lift
up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found, cor-
rect its cause.
3) Drain old oil and pour proper amount of gear oil as specified be-
low (roughly up to level hole).
4) Apply sealant to thread of drain plug (b) and torque plugs to
specification.
