Pressure Testing

A WARNING
•   While testing, be careful of the rotating front wheels.
•   Make sure lifts, jacks, and safety stands are placed properly. (see page 1-10 thru 1-12).

CAUTION:
•   Before testing, be sure the transmission fluid is filled to the proper level.
•   Warm up the engine before testing.

1. Raise the car (see page 1-10 thru 1-12).

2. Warm up the engine, then stop the engine and connect a tachometer.

3. Connect the oil pressure gauge to each inspection hole(s).

TORQUE: 18 N•m (1.8 kg-m, 12 Ib-ft)

CAUTION: Connect the oil pressure gauge securely, be sure not to allow dust and other foreign particles to enter the inspection hole.
NOTE: Use the A/T Oil Pressure Gauge Set or A/T Low Pressure Gauge and the Oil Pressure Gauge Hose Assembly.

4. Start the engine and measure the respective pressure as follows.
•   Line Pressure
•   Clutch Pressure
•   Clutch Low/High Pressure
•   Throttle A/Throttle B Pressure
•   Governor Pressure

5. Install a new washer and the sealing bolt in the inspection hole and tighten to the specified torque.

TORQUE: 18 N•m (1.8 kg-m, 12 lb-ft)

NOTE: Do not reuse old aluminum washers.

•   Line Pressure

-1. Set the parking brake and block both rear wheels securely.

-2. Run the engine at 2,000 rpm.
-3. Shift the select lever to N or P.
-4. Measure line pressure.

PRESSURE	SELECTOR POSITION	SYMPTOM	PROBABLE CAUSE	FLUID PRESSURE
				Standard	Service Limit
Line	N or P	No (or low) line pressure	Torque converter, oil pump pressure regulator, torque converter check valve, oil	850-900 kPa (8.5-9.0 kg/cm2, 121 -128 psi)	800 kPa (8.0 kg/cm2, 114 psi)

NOTE: Higher pressures may be indicated if measurements are made in selector positions other than I N or    P .
