Large Shock. N->R Position

5. Large Shock. N -> R Position

SYMPTOM: There is large shock when changing from N to R position.

1. CHECK SELF-DIAGNOSTIC RESULTS





Does self-diagnosis show damage to A/T fluid temperature sensor, line pressure solenoid valve or throttle position sensor [accelerator pedal position (APP) sensor] circuit?
Yes or No
Yes >>GO TO 2.
No >>GO TO 3.

2. CHECK DAMAGED CIRCUIT
Check damaged circuit. DTC P0710; P0745; P1705.

3. CHECK THROTTLE POSITION SENSOR [ACCELERATOR PEDAL POSITION (APP) SENSOR]





Check throttle position sensor [accelerator pedal position (APP) sensor]. DTC P0221; P0226.
OK or NG
OK >>GO TO 4.
NG >>Repair or replace throttle position sensor [accelerator pedal position (APP) sensor].

4. CHECK LINE PRESSURE





Check line pressure at idle with selector lever in D position.
OK or NG Line Pressure Test
OK >>GO TO 6.
NG >>GO TO 5.

5. DETECT MALFUNCTIONING ITEM
1. Remove control valve assembly.
2. Check the following items:
- Valves to control line pressure (Pressure regulator valve, pressure modifier valve, pilot valve and pilot filter)
- Line pressure solenoid valve
OK or NG
OK >>GO TO 6.
NG >>Repair or replace damaged parts.

6. CHECK SYMPTOM
Check again.
OK or NG
OK >>INSPECTION END
NG >>GO TO 7.

7. 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.
OK or NG
OK >>INSPECTION END
NG >>Repair or replace damaged parts.
