LINE PRESSURE TEST PORTS

Location of line pressure test ports are shown in the figure.
• Always replace pressure plugs as they are self-sealing bolts.

LINE PRESSURE TEST PROCEDURE

1.

Check ATF and engine oil levels. If necessary, add ATF or
engine oil.

2.

Drive vehicle for approx. 10 minutes or until engine oil and ATF
reach operating temperature.

3.

Install oil pressure gauge to corresponding line pressure test
port.

4.

Set parking brake and block wheels.

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

CAUTION:

• Keep the brake pedal pressed all the way down during

measurement.

• When measuring the line pressure at the stall speed, refer

to "STALL TEST".

Judgement

Suspected 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

TM-14, "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

ROAD TEST

ROAD TEST

Description

INFOID:0000000001726682

DESCRIPTION

• The purpose of the test is to determine 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

TM-482

.

2.

Check at idle. Refer to

TM-483

.

3.

Cruise test
• Inspection all the item from Part 1 to Part 3. Refer to

TM-485

,

TM-487

and

TM-488

.

• Before road test, familiarize yourself with all test procedures and

items to check.

• Perform tests on all items until specified symptom is found. Trou-

bleshoot the items which are checked out to be no good after road
test. Refer to

XX-XX, "*****"

,

XX-XX, "*****"

and

XX-XX, "*****"

.

Check Before Engine Is Started

INFOID:0000000001726683

1.

CHECK OD OFF INDICATOR LAMP

1.

Park vehicle on flat surface.

2.

Move selector lever to “P” position.

3.

Turn ignition switch OFF. Wait at least 5 seconds.

4.

Turn ignition switch ON. (Do not start engine.)

Does OD OFF indicator lamp come on for about 2 seconds?

YES

>> 1.

Turn ignition switch OFF.

2.

Perform self-diagnosis and note NG items.
Refer to

XX-XX, "*****"

,

XX-XX, "*****"

.

3.

Go to

TM-483, "Check at Idle"

.

NO

>> Stop “Road Test”. Go to

TM-138, "OD OFF Indicator

Lamp Does Not Come On"

.
