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 instruction 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
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
