3. Performance Test
A: STALL TEST
1. GENERAL
The stall test is of extreme importance in diagnosing the
condition of the automatic transmission and the engine. It
should be conducted to measure the engine stall speeds in
all shift ranges except the P and N ranges.
Purposes of the stall test:
1) To check the operation of the automatic transmission
clutch.
2) To check the operation of the torque converter clutch.
3) To check engine performance.
2. TEST METHODS
Preparations before test:
1Check that throttle valve opens fully.
2Check that engine oil level is correct.
3Check that coolant level is correct.
4Check that ATF level is correct.
5Check that differential gear oil level is correct.
6Increase ATF temperature to 60 to 80°C (140 to 176°F)
by idling the engine for approximately 30 minutes (with
select lever set to“N”or“P”).
1) Install an engine tachometer at a location visible from
the driver’s compartment and mark the stall speed range
on the tachometer scale.
2) Place the wheel chocks at the front and rear of all
wheels and engage the parking brake.
3) Move the manual linkage to ensure it operates properly,
and shift the select lever to the 2 range.
B3M0286B
4) While forcibly depressing the foot brake pedal, gradu-
ally depress the accelerator pedal until the engine operates
at full throttle.

3-2SERVICE PROCEDURE
3. Performance Test

5) When the engine speed is stabilized, read that speed
quickly and release the accelerator pedal.
6) Shift the select lever to Neutral, and cool down the
engine by idling it for more than one minute.
7) Record the stall speed.
8) If stall speed in 2 range is higher than specifications,
forward clutch slipping on brake band slipping may occur.
To identify it, conduct the same test as above in D range.
9) Perform the stall tests with the select lever in the R
range.
CAUTION:
Do 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 deterio-
rate and the clutch and brake band 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.
If 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 transmis-
sion from sustaining damage.

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
