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

Description

INFOID:0000000001696152

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-180

.

2.

Check at idle. Refer to 

TM-181

.

3.

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

TM-183

,

TM-185

 and 

TM-186

.

• 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:0000000001696170

1.

CHECK OD OFF INDICATOR LAMP
