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

ing portion
ITorque converter clutch case and oil pump
housing jointing portion
ITransmission case and extension case jointing

stall speed range on the tachometer scale.
3) Place the wheel chocks at the front and rear of
all wheels and engage the parking brake.
4) Move the manual linkage to ensure it operates
properly, and shift the select lever to the 2 range.
5) While forcibly depressing the foot brake pedal,
gradually depress the accelerator pedal until the
engine operates at full throttle.
B3M0286B
6) When the engine speed is stabilized, read that
speed quickly and release the accelerator pedal.
7) Shift the select lever to Neutral, and cool down
the engine by idling it for more than one minute.
8) Record the stall speed.
9) If stall speed in 2 range is higher than
specifications, low clutch slipping and 2-4 brakeslipping may occur. To identify it, conduct the same
test as above in D range.
10) Perform the stall tests with the select lever in
the R range.
NOTE:
IDo not continue the stall test for MORE THAN
FIVE SECONDS at a time (from closed throttle,
fully open throttle to stall speed reading). Failure to
follow this instruction causes the engine oil and
ATF to deteriorate and the clutch and brake to be
adversely affected.
Be sure to cool down the engine for at least one
minute after each stall test with the select lever set
in the P or N range and with the idle speed lower
than 1,200 rpm.
IIf the stall speed is higher than the specified
range, attempt to finish the stall test in as short a
time as possible, in order to prevent the automatic
transmission from sustaining damage.Stall speed (at sea level):
2200 cc 2,200 Ð 2,600 rpm
