Judgement of Line Pressure Test
Road TestINFOID:0000000005928095
DESCRIPTION
• The purpose of the test is to det
ermine overall performance of A/T
and analyze causes of malfunctions.
• The road test consists of the following three parts:
1. Check before engine is started. Refer to AT- 5 6
.
2. Check at idle. Refer to AT- 5 6
.
3. Cruise test • Inspection all the item from Part 1 to Part 3. Refer to AT- 5 8
,
AT- 6 1
and AT- 6 2 .

Line Pressure"Sta ll sp ee d
JudgementSuspected parts
At idle Line 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 2 , "
Shift Mechanism".
Line pressure is high. • Accelerator pedal position signal malfunction
• 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
speed Line pressure is low.
• Accelerator pedal position signal malfunction
• 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
1. Apply foot brake.
2. Move selector lever to “R” position.
Is there large shock when changing from
“N” to “R” position?
YES >> • Mark the box on the “Diagnostic Worksheet Chart”.•Go to AT-184, "
Large Shock "N" → "R" Position" .
• Continue “Road Test”.
NO >> GO TO 6.
6.CHECK VEHICLE MOVE
Release foot brake for several seconds.
Does vehicle creep backward when foot brake is released?
YES >> GO TO 7.
NO >> • Mark the box on the “Diagnostic Worksheet Chart”. •Go to AT-185, "
Vehicle Does Not Creep Backward in
"R" Position" .
• Continue “Road Test”.
7.CHECK VEHICLE MOVE
Move selector lever to “D”, “2” and “1” positions and check if vehicle
creeps forward.
Does vehicle creep forward in all three positions?
YES >> Go to AT-58, "Cruise Test - Part 1" .
NO >> • Mark the box on the “Diagnostic Worksheet Chart”.
•Go to AT-186, "
Vehicle Does Not Creep Forward in
"D", "2" or "1" Position" .
• Continue “Road Test”.
Cruise Test - Part 1INFOID:0000000005928098
1.CHECK STARTING GEAR (D1 ) POSITION
1. Drive vehicle for approximately 10 minutes to warm engine oil and ATF up to operating temperature.
2. Park vehicle on flat surface.
