7. Brake Fluid
A: REPLACEMENT
CAUTION:
IThe FMVSS No. 116, fresh DOT3 or 4 brake
fluid must be used.
ICover bleeder with waste cloth, when loos-
ening it, to prevent brake fluid from being
splashed over surrounding parts.
IAvoid mixing different brands of brake fluid
to prevent degrading the quality of the fluid.
IBe careful not to allow dirt or dust to get into
the reservoir tank.
NOTE:
IDuring bleeding operation, keep the clutch
reserve tank filled with brake fluid to eliminate entry
of air.
IClutch pedal operating must be very slow.
IFor convenience and safety, it is advisable to
have two man working.IThe amount of brake fluid required is approxi-
mately 70 m(2.4 US fl oz, 2.5 Imp fl oz) for total
clutch system.
1) Either jack-up vehicle and place a safety stand
under it, or lift-up vehicle.
2) Remove both front and rear wheels.
3) Draw out the brake fluid from reserve tank with
syringe.
4) Refill reservoir tank with recommended brake
fluid.
Recommended brake fluid:
FMVSS No. 116, fresh DOT3 or 4 brake
fluid
5) Bleed air from oil line with the help of a co-
worker.

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
2500 cc 2,200 Ð 2,600 rpm

8. Time Lag Test
A: INSPECTION
1. GENERAL INFORMATION
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 low clutch, reverse clutch, low &
reverse brake and one-way clutch.
CAUTION:
IPerform the test at normal operation fluid
temperature 60 to 80ÉC (140 to 176ÉF).
IBe sure to allow a one minute interval
between tests.
IMake three measurements and take the aver-
age value.
2. TEST METHODS
1) Fully apply the parking brake.
2) Start the engine.
Check idling speed (A/C OFF).
ªNº range: 800±100 rpm
3) Shift the shift lever from ªNº to ªDº range.
Using a stop watch, measure the time it takes from
shifting the lever until the shock is felt.
Time lag: Less than 1.2 seconds
4) In same manner, measure the time lag for ªNº
®ªRº.
Time lag: Less than 1.5 seconds
3. EVALUATION
1) If ªNº®ªDº time lag is longer than specified:
ILine pressure too low
ILow clutch worn
IOne-way clutch not operating properly
2) If ªNº®ªRº time lag is longer than specified:
ILine pressure too low
IReverse clutch worn
ILow & reverse brake worn
9. Line Pressure Test
A: MEASUREMENT
1. GENERAL INFORMATION
If the clutch or the brake shows a sign of slippage
or shifting sensation is not correct, the line pres-
sure should be checked.
IExcessive shocks during upshifting or shifting
takes place at a higher point than under normal
circumstances, may be due to the line pressure
being too high.
ISlippage or inability to operate the vehicle may,
in most cases, be due to loss of oil pressure for the
operation of the clutch, brake or control valve.
1) Line pressure measurement (under no load)
CAUTION:
IBefore measuring line pressure, jack-up all
wheels.
IMaintain temperature of ATF at approxi-
mately 50ÉC (122ÉF) during measurement.
(ATF will reach the above temperature after
idling the engine for approximately 30 minutes
with select lever in ªNº or ªPº.)
2) Line pressure measurement (under heavy load)
CAUTION:
IBefore measuring line pressure, apply both
foot and parking brakes with all wheels
chocked (Same as for ªstallº test conditions).
IMeasure line pressure when select lever is in
ªRº, ª2º with engine under stall conditions.
IMeasure line pressure within 5 seconds after
shifting the select lever to each position. (If line
pressure needs to be measured again, allow
the engine to idle and then stop. Wait for at
least one minute before measurement.)
IMaintain the temperature of ATF at approxi-
mately 50ÉC (122ÉF) during measurement. (ATF
will reach the above temperature after idling
the engine for approximately 30 minutes with
the select lever in ªNº or ªPº.)
