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 .
Engine speed Line pressure [kPa (kg/cm
2 , psi)]
D, 2nd and 1st positions R position
Idle speed AT- 3 7 4 , "
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
