range (above the center between upper and lower
marks). When the transmission is hot, the level
should be above the center of upper and lower
marks, and when it is cold, the level should be
found below the center of these two marks.
CAUTION:
IUse care not to exceed the upper limit level.
IATF level varies with temperature. Remem-
ber that the addition of fluid to the upper limit
mark when the transmission is cold will result
in the overfilling of fluid.
4) Fluid temperature rising speed
IBy idling the engine
Time for temperature rise to 60ÉC (140ÉF) with
atmospheric temperature of 0ÉC (32ÉF): More than
25 minutes

Time for temperature rise to 30ÉC (86ÉF) with
atmospheric temperature of 0ÉC (32ÉF): Approx. 8
minutes
IBy running the vehicle
Time for temperature rise to 60ÉC (140ÉF) with
atmospheric temperature of 0ÉC (32ÉF): More than
10 minutes
5) Method for checking fluid level upon delivery or
at periodic inspection
Check fluid level after a warm-up run of approx. 10
minutes. During the warm-up period, the automatic
transmission functions can also be checked.
2. DIFFERENTIAL GEAR OIL LEVEL
1) Ensure the vehicle is in safe condition.
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 (F) and lower (L) marks. If it is below the
lower limit mark, add oil until the level reaches the
upper mark.

3. OIL LEAKAGE
It is difficult to accurately determine the precise
position of a oil leak, since the surrounding area
also becomes wet with oil. The places where oil
seals and gaskets are used are as follows:
1) Jointing portion of the case
ITransmission case and oil pump housing joint-
ing portion
ITorque converter clutch case and oil pump
housing jointing portion
ITransmission case and extension case jointing

4. AWD FUNCTION
If ªtight-corner brakingº occurs when the steering
wheel is fully turned at low speed:
1) Determine the applicable trouble code and
check the corresponding duty solenoid C (transfer)
for improper operation.
2) If the solenoid is operating properly, check
transfer clutch pressure.
3) If oil pressure is normal but ªtight-corner brak-
ingº occurs:
Check the transfer control valve for sticking, and

7. Stall Test
A: MEASUREMENT
1. GENERAL INFORMATION
The stall test is of extreme importance in diagnos-
ing the condition of the automatic transmission and
the engine. It should be conducted to measure the
engine stall speeds in R and 2 ranges.
Purposes of the stall test:
1) To check the operation of the automatic trans-
mission clutch.
2) To check the operation of the torque converter
clutch.
3) To check engine performance.
2. TEST METHODS
1) Preparations before test:
(1) Check that throttle valve opens fully.
(2) Check that engine oil level is correct.
(3) Check that coolant level is correct.
(4) Check that ATF level is correct.
(5) Check that differential gear oil level is cor-
rect.
(6) Increase ATF temperature to 50 to 80ÉC
(122 to 176ÉF) by idling the engine for approxi-
mately 30 minutes (with select lever set to ªNº
or ªPº).
