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 sensor circuit?

   Yes or No 

   1. Yes: Check damaged circuit. Refer to "DTC P0710 A/T FLUID TEMPERATURE SENSOR CIRCUIT " "DTC P0745 PRESSURE SOLENOID VALVE " or "DTC P1705 ACCELERATOR PEDAL POSITION SENSOR (THROTTLE POSITION SENSOR) ".
   2. No: GO TO 2.
2. CHECK ACCELERATOR PEDAL POSITION SENSOR (THROTTLE POSITION SENSOR 

   Check accelerator pedal position sensor (throttle position sensor). Refer to ACCELERATOR PEDAL POSITION SENSOR .

   OK or NG 

   1. OK: GO TO 3.
   2. NG: Repair or replace accelerator pedal position sensor (throttle position sensor).
3. CHECK LINE PRESSURE 

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

   OK or NG 

   1. OK: GO TO 4.
   2. NG:
      1. Remove 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
4. CHECK SYMPTOM 

   Check again.

   OK or NG 

   1. OK: INSPECTION END 
   2. NG:
      1. Perform TCM input/output signal inspection.
      2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
