1. Allow the rear wheels to rotate freely.
2. Run the engine at 2,000 rpm.
3. Shift the select lever as shown on the chart on
the next page.
4. Measure each clutch pressure.
While testing, be careful of the rotating
rear wheels.
4. Start the engine and measure the respective pressure
as follows.
Line Pressure/Clutch Pressure
Clutch Low/High Pressure
Throttle B 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, 13 Ib-ft)
NOTE: Do not reuse old aluminum washers.
While testing, be careful of the rotating rear wheels.
Make sure lifts are placed properly (see section 1).
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 section 1).
2. Warm up the engine, then stop the engine and
connect a tachometer.
3. Connect the oil pressure gauge to each inspection
hole(s).
18 N.m (1.8 kg-m, 12 Ib-ft)
CAUTION: Connect the oil pressure gauge
securely, being sure not to allow dust and other
foreign particles to enter the inspection hole.

Pressure Testing

Clutch Low/High Pressure Measurement
While testing, be careful of the rotat-
ing rear wheels.
-1. Allow the rear wheels to rotate freely.
-2. Start the engine and let it idle.
-3. Shift the select lever to position.
-4. Slowly press down the accelerator pedal to in-
crease engine rpm until pressure is indicated on
the oil pressure gauge. Then release the acceler-
ator pedal, allowing the engine return to an idle,
and measure the pressure reading.
-5. With the engine idling, press down the acceler-
ator pedal approximately 1/2 of its possible trav-
el and increase the engine rpm until pressure is
indicated on the gauge, measure the highest
pressure reading obtained.
-6. Repeat steps-4 and -5 for each clutch pressure
being inspected.

Throttle B Pressure Measurement
While testing, be careful of the rotat-
ing rear wheels.
-1. Allow the rear wheels to rotate freely.
-2. Disconnect the linear solenoid connector.
-3. Shift the select lever to position.
-4. Run the engine at 1,000 rpm.
-5. Measure full opened throttle B pressure.
-6. Connect battery voltage to the linear solenoid ter-
minal of the connector.
-7. Measure full closed throttle B pressure.
