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 that the DTC other than P0729, P0732, P0733, P0734, P0735 (6th, 2nd, 3rd, 4th, 5th 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.

Q:Is the check result normal?
YES: Go to Step 6.
NO: Repair or replace the failure section.

STEP 6. Hydraulic pressure test.

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.
