5. LARGE SHOCK, N -> D POSITION

SYMPTOM
A noticeable shock occurs when the shift lever is shifted from the "N" to "D" position.

DIAGNOSTIC PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULTS
Execute self-diagnosis.
Do the self-diagnosis results indicate A/T fluid temperature sensor, line pressure solenoid valve, or throttle sensor?
Yes >> Check the malfunctioning system. Refer to "DTC P0745 LINE PRESSURE SOLENOID VALVE", "DTC P1705 THROTTLE POSITION SENSOR", "DTC P1710 A/T FLUID TEMPERATURE SENSOR CIRCUIT".
No >>GO TO 2.
2. CHECK ACCELERATOR PEDAL POSITION SENSOR
Check the accelerator pedal position sensor.
- Refer to "DTC P0121 ACCELERATOR PEDAL POSITION (APP) SENSOR".
OK or NG
OK >> GO TO 3.
NG >> Repair or replace the accelerator pedal position sensor.
3. CHECK THE LINE PRESSURE
Check the line pressure with the engine idling in the "D" position.
- Refer to "LINE PRESSURE TEST". OK or NG
OK >>GO TO 4.
NG >> Check line pressure solenoid valve. Refer to "DTC P0745 LINE PRESSURE SOLENOID VALVE".
4. CHECK SYMPTOM
Check again.
OK or NG
OK >> INSPECTION END
NG >> GO TO 5.
5. CHECK TCM INSPECTION
1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
