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 accelerator pedal position (APP) sensor circuit?

   Yes or No

   • Yes: GO TO 2.
   • No: GO TO 3.

2. CHECK DAMAGED CIRCUIT 

   Check damaged circuit.

   • : Refer to "DTC P0710 A/T FLUID TEMPERATURE SENSOR CIRCUIT ", "DTC P0745 LINE PRESSURE SOLENOID VALVE " or "DTC P1705 THROTTLE POSITION SENSOR [ACCELERATOR PEDAL POSITION (APP) SENSOR] ".
3. CHECK LINE PRESSURE 

   Check line pressure at idle with selector lever in D position. Refer to "LINE PRESSURE TEST ".

   OK or NG

   • OK: GO TO 5.
   • NG: GO TO 4.
4. DETECT MALFUNCTIONING ITEM 
   1. Remove control valve assembly. Refer to "CONTROL VALVE ASSEMBLY AND ACCUMULATORS ".
   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
      • Oil pump assembly

   OK or NG

   • OK: GO TO 5.
   • NG: Repair or replace damaged parts.
5. CHECK SYMPTOM 

   Check again.

   OK or NG

   • OK: INSPECTION END 
   • NG: GO TO 6.
6. CHECK TCM INSPECTION 
   1. Perform TCM input/output signal inspection. Refer to "TCM TERMINALS AND REFERENCE VALUE ".
   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.
