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 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". P0710 P0745 P1705


No >> GO TO 2.







2. CHECK THROTTLE POSITION SENSOR
Check throttle position sensor. Refer to "DTC P0121 TP SENSOR" P0121.

OK or NG?

OK >> GO TO 3.

NG >> Repair or replace throttle position sensor.






3. CHECK LINE PRESSURE


Check line pressure at idle with selector lever in D position.

OK or NG?

OK >> GO TO 4.

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


4. 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.
