TROUBLESHOOTING (G4A-HL) 7B
STEP 3 (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.

1. Apply the parking brake and position wheel chocks
to prevent the car from rolling forward.
Note
Place the car on a flat, level surface.
2. Run the engine so that the automatic transaxle fluid
reaches specified temperature.
3. While the engine is idling, shift the select lever from
P to L or P to 1 and back again.
4. Let the engine idle.
5. Shift the select lever to P.

7C TROUBLESHOOTING
STEP 1 (PRELIMINARY INSPECTION)
In this step, the main points related to the automatic transaxle are checked. These items must be kept
in the correct condition at all times in order to assure proper operation of the automatic transaxle.
1. Automatic Transaxle Fluid (ATF)
Check ATF level and condition. (Refer to page 7C—25.)
2. Selector Lever
Check selector lever position and adjust it if necessary. (Refer to page 7C—26.)
76G07C-018
3. Oil Leakage
Check for oil leakage.
(1) Warm up the ATF.
(2) Apply the parking brake and block the wheels
to prevent the vehicle from rolling.
(3) Shift the selector lever to R range.
(4) Check if oil leaks from the noted oil seals or
gaskets.
(5) If oil leaks, replace the seal or gasket.
