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 >> 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].
No >> GO TO 2.

2. 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 3.
NG >>
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
^ Oil pump assembly

3. CHECK SYMPTOM
Check again.
OK or NG
OK >> INSPECTION END
NG >>
1. Perform TCM input/output signal inspection. Pinout Values and Diagnostic Parameters
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
