INSPECTION PROCEDURE 5: Gears cannot be shifted at all, or a certain gear shift (1st to 2nd, 2nd to
3rd, etc.) is not made.
.
TROUBLESHOOTING HINTS (THE MOST
LIKELY CAUSES FOR THIS CONDITION:)
• Non-genuine device installation: TCM voltage
drop
• Improper fixing of the electric wiring, poor inser-
tion of the connector, poor contact of the inside
PIN
• Poor adjustment of transmission range switch
• Failure of the transmission range switch main unit
• Malfunction of the TCM
• TCM power supply or ground failure
• A/T failure: Hydraulic system (valve body assem-
bly), driving force transmission system
(clutch/brake)
DIAGNOSIS
STEP 1. Check the electrical equipment.
Q: Is the non-genuine electrical equipment (car navigator,
audio devices, etc.) installed?
YES : Remove the power supply wiring and signal lines of
the equipment.
NO : Go to Step 2
STEP 2. Check the electric system.
Check if there is an improper fixing of the electric wiring, poor
insertion of the connector, and poor contact.
Q: Is the check result normal?
YES : Go to Step 3.
NO : Adjust and repair.
STEP 3. Check and adjust the transmission range switch.
Refer to
,
.
If the transmission range switch has a failure, replace it, and
then check the trouble symptom again.
Q: Is the check result normal?
YES : The procedure is complete.
NO : Go to Step 4.
STEP 4. Check the TCM power supply and ground.
Q: Is the check result normal?
YES : Go to Step 5.
NO : Repair the wiring.
STEP 5. Replace the TCM.
Q: Is the failure resolved?
YES : The procedure is complete.
NO : Go to Step 6.

• Malfunction of the torque converter
DIAGNOSIS
STEP 1. Check and adjust the transmission range switch.
Refer to
,
.
If the transmission range switch has a failure, replace it, and
then check the trouble symptom again.
Q: Is the check result normal?
YES : The procedure is complete.
NO : Go to Step 2.
STEP 2. Replace the TCM.
Q: Is the failure resolved?
YES : The procedure is complete.
NO : Go to Step 3.
STEP 3. Check the installation position of the transaxle
assembly and the engine.
Is the installation of transaxle assembly and the engine nor-
mal? Compare and check the axial direction position with the
same model vehicle.
Q: Is the check result normal?
YES : Go to Step 4.
NO : Repair the installation.
STEP 4. Check the transmission fluid.

NO : Go to Step 5.
STEP 3. 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 : Check and repair the leakage point of the
transmission fluid, add the transmission fluid, and
then go to Step 4.
STEP 4. Perform a hydraulic test.
Refer to
.
Q: Is the check result normal?
YES : The procedure is complete.
NO : Go to Step 5.
STEP 5. Remove the transaxle assembly from the vehicle.
