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 50 to 80°C (122 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.
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.
