Mitsubishi Outlander XL. Manual — part 485

STEP 5. Check the signals of input shaft speed sensor and
output shaft speed sensor.
Check the signals of C-37 TCM connector terminal No. 37 and
No. 38.
Refer to P.23A-145.

Q:Is the check result normal?

YES:

Go to Step 6.

NO:

Repair or replace the failure section.

STEP 6. Hydraulic pressure test
Refer to P.23A-145.

Q:Is the check result normal?

YES:

Go to Step 7.

NO:

Remove the A/T from the vehicle, then check and

repair the inside.

STEP 7. Erase the DTC code, and drive the vehicle for a
while.
Check that the normal code is displayed.

Q:Is the check result normal?

YES:

The procedure is complete.

NO:

Return to START.

AUTOMATIC TRANSAXLE MECHANICAL

AUTOMATIC TRANSAXLE DIAGNOSIS

STEP 1. Check the DTC.
Check that P0715 (input shaft speed sensor) and P0720 (output
shaft speed sensor) are set.

Q:Is the DTC set?

YES:

Check and repair the relevant DTC system.

NO:

Go to Step 2.

STEP 2. Check the DTC.
Check if the DTC other than P0736 (Reverse gear ratio) is set.

Q:Is the DTC set?

YES:

Check and repair the relevant DTC system.

NO:

Go to Step 3.

STEP 3. Check the transmission fluid properties.
Check the status of the transmission fluid properties (smell,
color, fouling).

｠

Black: A/T inside damage, seizure

｠

Milky: Water intrusion

Q:Is the check result normal?

YES:

Go to Step 4.

NO:

Remove the A/T from the vehicle, then check and

repair the inside.

STEP 4. Check the transmission fluid level.

Q:Is the check result normal?

YES:

Adjust the transmission fluid level, and then go to

Step 5.

NO:

Go to Step 5.

STEP 5. Check the signals of input shaft speed sensor and
output shaft speed sensor.
Check the signals of C-37 TCM connector terminal No. 37 and
No. 38.
Refer to P.23A-145.

Q:Is the check result normal?

YES:

Go to Step 6.

NO:

Repair or replace the failure section.

STEP 6. Hydraulic pressure test
Refer to P.23A-145.

Q:Is the check result normal?

YES:

Go to Step 7.

NO:

Remove the A/T from the vehicle, then check and

repair the inside.

STEP 7. Erase the DTC code, and drive the vehicle for a
while.
Check that the normal code is displayed.

Q:Is the check result normal?

YES:

The procedure is complete.
