(7) Apply the automatic transmission fluid (ATF) onto
the parts immediately prior to assembly, and the speci-
fied tightening torque should be observed carefully.
(8) Use vaseline if it is necessary to hold parts in the
position when assembling.
(9) Drain ATF and differential gear oil into a saucer so
that the conditions of fluid and oil can be inspected.
(10) Do not support axle drive shaft, stator shaft, input
shaft or various pipes when moving transmission from
one place to another.
(11) Always discard old oil seals and O-ring, and install
new ones.
(12) Do not reuse old aluminum (overrunning clutch
pipes, etc.) pipes, gaskets, spring pins. Install new
ones.
(13) Be sure to replace parts which are damaged,
worn, scratched, discolored, etc.

A: INSPECTION
1. ATF LEVEL
1) Raise ATF temperature to 60 to 80°C (140 to 176°F)
from 40 to 60°C (104 to 140°F) (when cold) by driving a
distance of 5 to 10 km (3 to 6 miles).
NOTE:
The level of ATF varies with fluid temperature. Pay atten-
tion to the fluid temperature when checking oil level.
2) Make sure the vehicle is level. After selecting all posi-
tions (P, R, N, D, 3, 2, 1), set the selector leveler in“P”
range. Measure fluid level with the engine idling.
NOTE:
After running, idle the engine for one or two minutes before
measurement.
3) If the fluid level is below the center between upper and
lower marks, add the recommended ATF until the fluid level
is found within the specified 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:
Use care not to exceed the upper limit level.
ATF level varies with temperature. Remember 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
By idling the engine
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 25 minutes

Time for temperature rise to 30°C (86°F) with atmo-
spheric temperature of 0°C (32°F): Approx. 8 minutes
By running the vehicle
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 10 minutes
5) Method for checking fluid level upon delivery or at peri-
odic inspection
Check fluid level after a warm-up run of approx. 10 min-
utes. During the warm-up period, the automatic transmis-
sion 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.
G3M0854
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:
Jointing portion of the case
Transmission case and oil pump housing jointing portion
Torque converter clutch case and oil pump housing joint-
ing portion
Transmission case and transmission cover jointing por-
tion (FWD)
Transmission case and extension case jointing portion
(AWD)

The point listed above should be checked for fluid leak.
Checking method is as follows:
(1) Place the vehicle in the pit, and check whether the
leaking oil is ATF or not. The ATF is wine red in color,
and can be discriminated easily from engine oil and
gear oil.
(2) Wipe clean the leaking oil and dust from a suspect-
able area, using a non-inflammable organic solvent
such as carbon tetrachloride.
(3) Run the engine to raise the fluid temperature, and
set the selector lever to“D”in order to increase the fluid
pressure and quickly detect a leaking point. Also check
for fluid leaks while shifting select lever to“R”,“2”, and
“1”.

B: ADJUSTMENT
1. BRAKE BAND
If the following abnormal shifting conditions are noted in a
road test, the brake band must be adjusted.
Improper brake band clearances and their symptoms
Clearance Problem
1. Too wide Upshift from 1st directly to 3rd gear occurs.
2. WideEngine rpm increases abruptly while upshifting from 1st
to 2nd gear or 3rd to 4th gear.
Time lag of at least one second occurs during kickdown
operation from 3rd to 2nd gear.
3. Small“Braking”symptom occurs while upshifting from 2nd to 3rd
gear.
4. Too smallUpshifts from 2nd to 4th gear and downshifts from 4th to
2nd gear occur repeatedly.
