TROUBLE DIAGNOSIS — BASIC INSPECTION
JUDGEMENT OF LINE PRESSURE TEST
Road TestECS007NZ
DESCRIPTION
●The purpose of the test is to determine overall performance of A/
T and analyze causes of problems.
●The road test consists of the following three parts:
1. Check before engine is started
2. Check at idle
3. Cruise test
●Before road test, familiarize yourself with all test procedures and
items to check.
●Conduct tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.
Refer to the following items.
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
●Line pressure leakage between oil strainer and pressure regulator valve
●Clogged strainer
Line pressure is low in particular posi-
tion.
●Line 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- 1 8 , "
Shift Mechanism" .
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
●Pilot valve sticking

TROUBLE DIAGNOSIS — BASIC INSPECTION
Cruise Test — Part 1
1. CHECK STARTING GEAR (D1 ) POSITION
1. Drive vehicle for approx. 10 minutes to warm engine oil and ATF up to operating
temperature.
2. Park vehicle on flat surface.
3. Set overdrive control switch to “ON” position.
4. Move selector lever to “P” position.
5. Start engine.
6. Move selector lever to “D” position.
7. Accelerate vehicle by constantly depressing accelerator pedal
halfway.
8. Does vehicle start from D
1 ?
Read gear position.
