5. 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 line pressure at stall speed, refer to AT-
43, "STALL TEST" .

Judgement Suspected parts
At idleLine 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”, “3” and “2” positions.
Therefore, fluid leakage exists at or around low and reverse brake circuit.
Refer to AT-18, "
CLUTCH AND BAND CHART" .
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
speedLine pressure is low.

Accelerator pedal position signal malfunction

Line pressure solenoid valve sticking

Short circuit of line pressure solenoid valve circuit
