Warning:
- When checking, beware of the rotating front wheels.
- Make sure the lift, jacks, and safety stands are positioned correctly.
Attention.
- Before checking, make sure the transmission fluid is filled to the correct level.
- Warm up the engine before checking.
1. Raise the car.
2. Warm up the engine, then stop and attach the tachometer.
3. Attach an oil pressure gauge to each inspection hole.
Torque: 18 Nm (1.8 kgf·m)
4. Start the engine and measure the appropriate pressure.
- Line pressure
- Clutch pressure
- Throttle pressure A/ Throttle pressure B
- Control pressure
5. Install a new washer and sealing bolt into the inspection hole and tighten to the specified torque.
Tightening torque: 18 Nm (1.8 kgf·m)
Note: Do not reuse old aluminum washers.
Line pressure measurement
1. Set the parking brake and block both rear wheels securely.
2. Accelerate the engine to 2000 rpm.
3. Switch to [N] or [P] position.
Note: High pressure readings may occur if measurements were taken in shift lever positions other than [N] or [P].
4. Measure the line pressure.

Warning: During testing, be careful not to spin the front wheels.
1. Set the parking brake and block both rear wheels securely.
2. Raise the front of the machine and place it on safety stands.
3. Allow the front wheels to rotate freely.
4. Accelerate the engine to 2000 rpm
5. Measure the pressure of each clutch.

Warning
- When checking, be careful not to rotate the front wheels.
- Allow the front wheels to rotate freely.
2. Remove the end of the throttle cable from the throttle control lever.
Note: Do not loosen the locknuts, just unhook the end of the cable.
3. Switch to [D4] or [D3] position.
4. Accelerate the engine at 1000 rpm.
5.Measure the pressure of fully closed throttle A and B.
6. Move the throttle control lever to the full throttle position.
7. Measure the pressure of the wide open throttle A and B.
