Component Tests and General Diagnostics

Warning:

- While testing, be careful of the rotating front wheels.
- Make sure lifts, jacks, and safety stands are placed properly.


CAUTION. Before testing, be sure the transmission fluid is filled to the proper level.

Warm up the engine before testing.

1. Raise the car.
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 lb-ft)


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 (1.8kg-rn, 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 or
- 4. Measure line pressure.









Clutch Pressure Measurement

Warning: While testing, be careful of the rotating front wheels.


- 1. Set the parking brake and block both rear wheels securely.
- 2. Raise the front of the car and support with safety stands.
- 3. Allow the front wheels to rotate freely.
- 4. Run the engine at 2,000 rpm.
- 5. Measure each clutch pressure.


Clutch Low/High Pressure Measurement


Warning: While testing, be careful of the rotating front wheels.


- 1. Allow the front wheels to rotate freely.





- 2.Remove the cable end of the throttle control cable from the throttle control lever.


NOTE:Do not loosen the locknuts, simply unhook the cable end.

- 3.Start the engine and let it idle.
- 4.Shift the select lever to D4 position.





- 5.Slowly move the throttle linkage to increase engine rpm until pressure is indicated on the oil pressure gauge. Then release the throttle linkage, allowing the engine to return to an idle, and measure the pressure reading.

- 6.Repeat step 5 for each clutch pressure being inspected.





- 7.With the engine idling, lift the throttle control lever up approximately 1/2 of its possible travel and increase the engine rpm until pressure is indicated on the gauge, then measure the highest pressure reading obtained.
- 8.Repeat step 7 for each clutch pressure being inspected.















Throttle A/Throttle B Pressure Measurement


Warning: While testing, be careful of the rotating front wheels.


- 1. Allow the front wheels to rotate freely.
- 2. Remove the cable end of the throttle control cable trom the throttle control lever.

NOTE; Do not loosen the locknuts, simply unhook the cable end.

- 3. Shift the selector lever to D4 or D3 position.
- 4. Run the engine at 1 000 rpm.
- 5. Measure full-closed throttle A/B pressure.
- 6. Move the throttle control lever to full-opened throttle position.
- 7. Measure full-opened throttle A/B pressure.









Governor Pressure Measurement

Warning: While testing, be careful of the rotating front wheels.

- 1.Allow the front wheels to rotate freely.
- 2.Run the vehicle at 38 mph (60 km/h).
- 3.Measure the governor pressure.
