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.

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

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.

Adjustment of the adjusting screw
1) Using a ST, immobilize the end of the 10 mm-screw
projecting on the left side of the transmission case, and
loosen the nut with a double-end wrench.
In the case of occurrence of problems 2. and 3. mentioned
previously, perform the adjustment by loosening or tighten-
ing the nut within a range of 3/4 turn from this state.
ST 398603610 SOCKET WRENCH
CAUTION:
Do not loosen excessively; otherwise, the band strut
on the servo piston will drop off.

2) In case of the occurrence of problems 1. and 4. men-
tioned previously, perform the adjustment as follows:
Adjusting procedure: Tighten adjust screw to 9 N⋅m (0.9
kg-m, 6.5 ft-lb) torque, then back off three turns.
CAUTION:
Do not tighten the adjusting screw with an excessively
large torque.

2. INHIBITOR SWITCH
The inhibitor switch allows the back-up lights to turn on
when the select lever is in the R range and the starter
motor to start when the lever is in the N or P range. It also
monitors the input signal electronically controlled for each
range and turns on the corresponding range light on the
instrument panel.
When light operation, driving condition or starter motor
operation is erroneous, first check the shift linkage for
improper operation. If the shift linkage is functioning
properly, check the inhibitor switch.
(1) Disconnect cable end from select lever.
(2) Disconnect inhibitor switch connector.
(3) Check continuity in inhibitor switch circuits with
select lever moved to each position.
CAUTION:
Also check that continuity in ignition circuit does not
exist when selector lever is in R, D, 3, 2 and 1 ranges.

(4) Check if there is continuity at equal points when the
select lever is turned 1.5°in both directions from the N
range.
If there is continuity in one direction and the continuity
in the other or if there is continuity at unequal points,
adjust the inhibitor switch.
G3M0294
(1) Loosen the three inhibitor switch securing bolts.
(2) Shift the select lever to the N range.
(3) Insert ST as vertical as possible into the holes in
the inhibitor switch lever and switch body.
