7C TROUBLESHOOTING
STEP 2 (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. Set the parking brake and block the front and rear of the wheels.
Pull the parking brake Water temperature

7C TROUBLESHOOTING
STEP 4 (ROAD TEST)
This step is performed to check for problems in the various ranges. If these tests show any problems,
adjust or replace by referring to the QUICK DIAGNOSIS CHART and mechanical sections.
Caution
Perform the test at normal ATF operating temperature (50—80°C, 122—176°F).
Gearshift Function Check Items
1. Shift shock must be minimal, and shifting must be smooth.
2. Engine speed must not run away, and the shifting must not be delayed.
3. Transaxle must shift through Di D2 -»• D3 in D range.
4. Transaxle must shift from 3rd in D range to 2nd gear when 2 range is selected.
5. Transaxle must shift from 2nd to 1st when 1 range is selected from 3rd gear in D range.
6. Transaxle must not upshift in 1 range.
7. Transaxle must remain in 2nd gear in 2 range.
8. Transaxle must positively lock in P range.
The transaxle must positively lock when P range is selected while moving at a speed below 4 km/h
(2.5 mph) on level ground. The transaxle must positively lock when set in P range with the vehicle
on a gentle slope and the brakes disengaged.

Inspection of Level
1. Apply the parking brake and block the wheels to
prevent the vehicle from rolling.
Note
Place the car on a flat, level surface.
2. Run the engine so that the automatic transaxle fluid
reaches operating temperature.
3. While the engine is idling, shift the select lever from
P to 1 and back again.
4. Let the engine idle.
5.Shift the select lever to P.

POWER STEERING PRESSURE
1. Disconnect the high-pressure hose of the gear
housing side, and attach the SST.
Tightening torque:
39—49 N-m (4.0—5.0 m-kg, 29—36 ft-lb)
2. Bleed air from the system.
3. Open the gauge valve fully, then start the engine
and turn the steering wheel fully left and right to
raise the fluid temperature to 50—60°C
(122—140°F)
4. To measure the fluid pressure generated by the
oil pump, close the gauge valve completely and
increase the engine speed to 1,000—1,500 rpm.
If the fluid pressure is low, replace the oil pump
assembly.
Warning
If the valve is left closed for more than 15 sec-
onds, the fluid temperature will increase ex-
cessively and adversely affect the oil pump.

Front 8,093—8,829 kPa
(82.5—90.0 kg/cm2, 1,173—1,280 psi)
Rear 7,112—7,848 kPa
(72.5—80.0 kg/cm2, 1,031—1,138 psi)
To measure the fluid pressure generated at the
gear housing, first open the gauge valve complete-
ly, increase the engine speed to 1,000—1,500
rpm, and then turn the steering wheel fully to the
left and right.
Warning
If the steering wheel is kept in the fully turned
position for more than 15 seconds, the fluid
temperature will rise excessively.
