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.

3-2SERVICE PROCEDURE
2. On-Car Services

B: TIME LAG TEST
1. GENERAL
If the shift lever is shifted while the engine is idling, there
will be a certain time elapse or lag before the shock can be
felt. This is used for checking the condition of the forward
clutch, reverse clutch, low & reverse brake, forward one-
way clutch and low one-way clutch.
CAUTION:
Perform the test at normal operation fluid tempera-
ture 60 to 80°C (140 to 176°F).
Be sure to allow a one minute interval between tests.
Make three measurements and take the average
value.
2. TEST METHODS
1) Fully apply the parking brake.
2) Start the engine.
Check idling speed (A/C OFF).
“N”range: 800±100 rpm
3) Shift the shift lever from“N”to“D”range.
Using a stop watch, measure the time it takes from shift-
ing the lever until the shock is felt.
Time lag: Less than 1.2 seconds
4) In same manner, measure the time lag for“N”,“R”.
Time lag: Less than 1.5 seconds
3. EVALUATION
1) If“N”,“D”time lag is longer than specified:
Line pressure too low
Forward clutch worn
Low one-way clutch not operating properly
2) If“N”,“R”time lag is longer than specified:
Line pressure too low
Reverse clutch worn
Low & reverse brake worn
Forward one-way clutch not operating properly

19) Install rear cover and tighten bolts to specified torque.
Tightening torque:
29±5 N⋅m (3.0±0.5 kg-m, 21.7±3.6 ft-lb)
F: INSTALLATION
To install, reverse the removal sequence.
1) Install the air breather cap tapping with a plastic ham-
mer.
CAUTION:
Be sure to install new air breather cap.
2) Position front member on body by passing it under park-
ing brake cable and securing to rear differential.
NOTE:
When installing rear differential front member, do not con-
fuse the installation sequence of the upper and lower stop-
pers.

While engine is running with/
without steering turned.Loosened installation of oil pump,

Abnormal inside of oil pump, hoseReplace oil pump, hose, if the
noise can be heard when running
as well as stand still.
Torque converter growl

Creaking noise (intermittent)
While engine is running with
steering turned.Abnormal inside of gearboxReplace bad parts of gearbox.
Abnormal bearing for steering
shaftApply grease or replace.
*9
Generates when turning steering
wheel with brake (service or park-
ing) applied.If the noise goes off when brake
is released, it is normal.
*10
Vibration
While engine is running with/
without steering turned.
Too low engine speed at startAdjust and instruct customers.
Vane pump aerationFix wrong part.
Vent air.
Damaged valve in oil pump, gear-
boxReplace oil pump, bad parts of
gearbox.
Looseness of play of steering,
suspension partsRetighten.
*8 Oil pump makes whine or growl noise slightly due to its mechanism. Even if the noise can be heard when steering wheel
is turned at stand still there is no abnormal function in the system provided that the noise eliminates when the vehicle is
running.
*9 When stopping with service brake and/or parking brake applied, power steering can be operated easily due to its light
steering effort. If doing so, the disk rotates slightly and makes creaking noise. The noise is generated by creaking between
the disk and pads. If the noise goes off when the brake is released, there is no abnormal function in the system.
*10 There may be a little vibration around the steering devices when turning steering wheel at standstill, even though the com-
ponent parts are properly adjusted and have no defects.
Hydraulic systems are likely to generate this kind of vibration as well as working noise and fluid noise because of com-
bined conditions, i.e., road surface and tire surface, engine speed and turning speed of steering wheel, fluid temperature
and braking condition.
This phenomena does not indicate there is some abnormal function in the system.
The vibration can be known when steering wheel is turned repeatedly at various speeds from slow to rapid step by step
with parking brake applied on concrete road and in“D”range for automatic transmission vehicle.
