Large Shock. “N” → “R” PositionECS004SY
SYMPTOM:
There is large shock when changing from “N” to “R” position.
1. CHECK SELF-DIAGNOSTIC RESULTS
Perform self-diagnosis. Refer to AT- 4 5 , "
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)" or AT- 5 2 ,
"Diagnostic Procedure Without CONSULT-II" .
Do the self-diagnosis results indicate A/T fluid temperature sensor, line pressure solenoid valve, accelerator
pedal position (APP) sensor circuit?
YES >>
Check damaged circuit. Refer to the following items.
–AT- 1 5 4 , "DTC P0745 LINE PRESSURE SOLENOID VALVE"
–AT- 1 7 3 , "DTC P1705 ACCELERATOR PEDAL POSITION (APP) SENSOR"
– AT- 1 8 4 , "DTC BATT/FLUID TEMP SEN (A/T FLUID TEMP SENSOR CIRCUIT AND TCM
POWER SOURCE)"
NO >> GO TO 2
2. CHECK LINE PRESSURE
Check line pressure at idle with selector lever in D position. Refer to
AT- 6 8 , "
Line Pressure Test" .
OK or NG
OK >> GO TO 3.
NG >> 1. Remove control valve assembly. Refer to AT- 4 0 4 ,
"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 fil-
ter)
–Line pressure solenoid valve
–Oil pump assembly. Refer to AT- 4 4 3 , "Oil Pump" .
3. CHECK SYMPTOM
Check again. Refer to AT- 7 2 , "
2. CHECK AT IDLE" .
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection. Refer to AT- 9 4 , "
TCM Terminals and Reference
Va l u e" .
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

5. Start engine and measure line pressure at idle and stall speed.

When measuring line pressure at stall speed, follow the
stall test procedure.

Judgement Suspected parts
At idleLine pressure is low in all positions.

Oil pump wear

Control piston damage

Pressure regulator valve or plug sticking

Spring for pressure regulator valve damaged

Fluid pressure leakage between oil strainer and pressure regulator valve

Clogged strainer
Line pressure is low in particular posi-
tion.

Fluid pressure leakage between manual valve and particular clutch

For example, line pressure is:
− Low in R and 1 positions, but
− Normal in D and 2 positions.
Therefore, fluid leakage exists at or around low and reverse brake circuit.
Refer to AT- 2 3
.
Line pressure is high.

Maladjustment of throttle position sensor

A/T fluid temperature sensor damaged

Line pressure solenoid valve sticking

Short circuit of line pressure solenoid valve circuit

Pressure modifier valve sticking

Pressure regulator valve or plug sticking

Open in dropping resistor circuit
At stall
speedLine pressure is low.

Maladjustment of throttle position sensor

Line pressure solenoid valve sticking

Short circuit of line pressure solenoid valve circuit

Pressure regulator valve or plug sticking

Pressure modifier valve sticking
