4. Set parking brake and block wheels.
IContinue to depress brake pedal fully while line pressure
test is being performed at stall speed.
5. Start engine and measure line pressure at idle and stall speed.
I When measuring line pressure at stall speed, follow the
stall test procedure.
Line pressure: Refer to SDS, AT-201.
JUDGEMENT OF LINE PRESSURE TEST
Judgement Suspected parts
At idle Line pressure is low in all
positions.
I
Oil pump wear
I Control piston damage
I Pressure regulator valve or plug sticking
I Spring for pressure regulator valve damaged
I A/T fluid pressure leakage between oil strainer and pressure regulator valve
I Clogged strainer
Line pressure is low in par-
ticular position. I
Fluid pressure leakage between manual valve and particular clutch
I For example, line pressure is:
Ð Low in ªRº and ª1º positions,
Ð Normal in ªDº and ª2º positions.
Then, fluid leakage exists at or around low and reverse brake circuit.
Refer to ªCLUTCH AND BAND CHARTº, AT-11.
Line pressure is high. IMal-adjustment of throttle position sensor
I A/T fluid temperature sensor damaged
I Line pressure solenoid valve sticking
I Short circuit of line pressure solenoid valve circuit
I Pressure modifier valve sticking
I Pressure regulator valve or plug sticking
I Open in dropping resistor circuit
At stall speed Line pressure is low.
IMal-adjustment of throttle position sensor
I Line pressure solenoid valve sticking
I Short circuit of line pressure solenoid valve circuit
I Pressure regulator valve or plug sticking
