5. Stall Test
A: INSPECTION
NOTE:
The stall test is extremely important in diagnosing
the condition of an automatic transmission and en-
gine. The test is necessary to measure the engine
stall speeds in “R” and “2nd of manual mode”.
Purposes of the stall test:
• Operational check of the automatic transmission
clutch
• Operational check of the torque converter clutch
• Engine performance check
1) Check that the throttle valve fully opens.
2) Check that the engine oil level is correct.
3) Check that the coolant level is correct.
4) Check that the ATF level is correct.
5) Check that the differential gear oil level is cor-
rect.
6) Increase the ATF temperature to 70 to 80°C
(158 to 176°F) by idling the engine for approximate-
ly 30 minutes (with select lever set to “N” or “P”).
7) Place the wheel chocks at the front and rear of
all wheels and apply the parking brake.
8) Move the select lever to ensure it operates prop-
erly, then set to “2nd gear of manual mode”.
9) While stepping hard on the brake pedal, slowly
depress the accelerator pedal to full throttle.
10) When the engine speed is stabilized, quickly
record the engine speed and release accelerator
pedal.
11) Shift the select lever to “N” range, and cool
down the engine by idling it for one minute or more.
12) If the stall speed in “2nd gear of manual mode”
is higher than specifications, low clutch slipping
and 2-4 brake slipping may occur. To identify this,
conduct the same test as above in “R” range.
