TROUBLESHOOTING (G4A-EL) 7B
STEP 4 (STALL TEST)
This step is performed to determine if there is slippage of the friction elements or malfunction of the
hydraulic components.
Preparation
Check the following items prior to testing:
1. Engine coolant, engine oil and ATF levels.
2. Warm the engine thoroughly to raise the ATF temperature to operating level (50—80°C, 122—176°F).
3. Engage the parking brake and use wheel chocks at the front and rear wheels.

7B TROUBLESHOOTING (G4A-EL)
Procedure
86U07B-034
1. Block the wheels and apply the parking brake.
2. Connect a tachometer to the engine.
3. Shift the selector lever to R.
4. Firmly depress the foot brake with the left foot, and gently depress the accelerator pedal with the right.
5. When the engine speed no longer increases, quickly read the engine speed and release the ac-
celerator.
Caution
Steps 4 ->• 5 must be done within 5 seconds.
6. Move the selector lever to N and let the engine idle for at least one minute.
Caution
The reason for idling for at least one minute is to cool the ATF and to prevent deterioration
of the fluid.
