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", "DTC P1705 THROTTLE POSITION SENSOR".
No >> GO TO 2.

2. CHECK THROTTLE POSITION SENSOR





Check throttle position sensor. Refer to "DTC P0121 TP SENSOR" (VG33E only) or "DTC P0121 TP SENSOR" (VG33ER only).

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. Refer to "Line Pressure Test".

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.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
