Line Pressure
Judgement of Line Pressure Test
Road Test INFOID:0000000004305320
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-56 .
2. Check at idle. Refer to AT-56 .
3. Cruise test • Inspection all the item from Part 1 to Part 3. Refer to AT-58 ,
AT-61 and
AT-62 .
Engine speed
Line pressure [kPa (kg/cm
2
, psi)]
D, 2nd and 1st positions R position
Idle speed AT-373, " Line Pressure "
Stall speed
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 AT-22, " 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

3. Push overdrive control switch. (OD OFF indicator lamp is off.)
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 half-way.
Read gear position. Refer to AT-79, " CONSULT-III Func-
tion (TRANSMISSION) " .
Does vehicle start from D YES >> GO TO 2.
NO >> • Mark the box on the “D iagnostic Worksheet Chart”.
• Go to AT-188, " Vehicle Cannot Be Started from D .
• Continue “Road Test”. Vehicle Speed at Which Gear Shifting Occurs " .
Read gear position, throttl e opening and vehicle speed.
Refer to AT-79, " CONSULT-III Function (TRANSMISSION) " .
Does A/T shift from D YES >> GO TO 3.
NO >> • Mark the box on the “D iagnostic Worksheet Chart”.
• Go to AT-190, " A/T Does Not Shift: D

• Continue “Road Test”. 8.
CHECK SHIFT-DOWN (D 4 TO D 3 )
Decelerate vehicle by applying foot brake lightly. Read gear position and engine speed. Refer to AT-79, " CON-
SULT-III Functi
on (TRANSMISSION) " .
Does engine speed return to idle smoothly when A/T is shifted from D 4 to D 3 ?
YES >> 1. Stop vehicle.
2. Go to AT-61, " Cruise Test - Part 2 " .
NO >> • Mark the box on the “D iagnostic Worksheet Chart”.
• Go to AT-197, " Engine Speed Does Not Return to Idle
(Light Braking D 4 → D 3 ) " .
• Continue “Road Test”.

CHECK STARTING GEAR (D 1 ) POSITION
1. Push overdrive control switch. (OD OFF indicator lamp is off.)
2. Move selector lever to “D” position.
3. Accelerate vehicle by half throttle again.
Read gear position. Refer to AT-79, " CONSULT-III Func-
tion (TRANSMISSION) " .
Does vehicle start from D 1 ?
YES >> GO TO 2.
NO >> • Mark the box on the “D iagnostic Worksheet Chart”.
• Go to AT-188, " Vehicle Cannot Be Started from D 1 " .
• Continue “Road Test”. 2.
CHECK SHIFT-UP AND SHIFT-DOWN (D 3 TO D 4 TO D 2 )
1. Accelerate vehicle to 80 km/h (50 MPH) as shown in the figure.
2. Release accelerator pedal and then quickly depress it fully.
Read gear position and th rottle opening. Refer to AT-79," CONSULT-III Function (TRANSMISSION) " .
Does A/T shift from D 4 to D 2 as soon as accelerator pedal is
depressed fully?
YES >> GO TO 3.
NO >> • Mark the box on the “D iagnostic Worksheet Chart”.
• Go to AT-190, " A/T Does Not Shift: D 1 → D 2 or Does
Not Kickdown: D 4 → D 2 " .
