Check of sound source and incoming route
(radiated sound, propagation sound, resonance,
etc.), and measurement at driver's seat, front
passenger's seat, and rear passenger's seat

2.

Change of sound during cold and after warm up
(Change of fluid, and hydraulic pressure)

3.

Change of sound with the engine speed

4.

Check of tone, and continuous/discontinuous
sound

DIAGNOSIS

STEP 1. Check the engine performance.
Check the sound of engine, auxiliary parts, and resonance/
nonresonance.

Q:Is the check result normal?

YES:

Go to Step 2.

NO:

Repair the failure, and perform adjustment.

STEP 2. Check the transmission fluid level.
Check if the transmission fluid level is adequate.

Q:Is the check result normal?

YES:

Go to Step 4.

NO:

Go to Step 3.

STEP 3. Check and repair the leakage point of the
transmission fluid.
Check and repair the leakage point of the transmission fluid, and
adjust the transmission fluid level. Then check if the abnormal
sound is generated.

Q:Is the check result normal?

YES:

The procedure is complete.

NO:

Go to Step 4.

STEP 4. Check the transmission fluid.
Check the transmission fluid for burning, fouling, and foreign
material.

Q:Is the check result normal?

YES:

Go to Step 5.

NO:

Go to Step 8.

STEP 5. Retest the system.
Check if the abnormal sound during idling occurs with vibration.

Q:Is the check result normal?

YES:

Go to Step 6.

AUTOMATIC TRANSAXLE DIAGNOSIS

NO:

Go to Step 7.

STEP 6. Check the torque converter.
Check the torque converter installation, change the installation
phase, and then check the trouble symptom.

Q:Is the check result normal?

YES:

The procedure is complete.

NO:

Go to Step 7.

STEP 7. Compare with another same model vehicle.

Q:Is there a difference from the same model vehicle?

YES:

Go to Step 8.

NO:

The procedure is complete.

STEP 8. Remove the transaxle assembly from the vehicle.
Disassemble and check the transaxle assembly to check if there
is a foreign material inside.

Q:Is the check result satisfactory?

YES:

Replace the transaxle assembly.

NO:

Replace the failure part.
