Evaluation:
HYDRAULIC TEST
1. MEASURE LINE PRESSURE
NOTICE:
• Perform the test at the normal operating ATF
temperature: 50 to 80
C (122 to 176F).
• The line pressure test should always be
performed with at least 2 people. One person
should observe the condition of the wheels or
wheel chocks while the other is performing the
test.
• Be careful to prevent SST's hose from interfering
with the exhaust pipe.
• This test must be performed after checking and
adjusting the engine.
• Perform the test with the A/C OFF.
• When conducting the stall test, do not continue
for more than 10 seconds.
(a) Warm up the ATF.
(b) Remove the test plug on the transaxle case center

wheels.
(d) Start the engine and check the idling speed.
(e) Keep your left foot firmly on the brake pedal and
move the shift lever to D.
(f) Measure the line pressure when the engine is idling.
Test Result Possible Cause
D range time lag exceeds standard value • Line pressure is low
• C1 clutch is worn
• F3 one-way clutch is not operating properly
• F4 one-way clutch is not operating properly
R range time lag exceeds standard value • Line pressure is low
• C3 clutch is worn
• B4 brake is worn
• F1 one-way clutch is not operating properly

PROBLEM SYMPTOMS TABLE
HINT:
• Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms
are listed in order of probability in the "Suspected area"
column of the table. Check each symptom by checking the
suspected areas in the order they are listed. Replace parts
as necessary.
• The Matrix Chart is divided into 2 chapters. When
troubleshooting, check Chapter 1 first. If instructions are
given in Chapter 1 to proceed to 2, proceed as instructed.
• If the instruction "Proceed to next circuit inspection shown
in problem symptoms table" is given in the flowchart for
each circuit, proceed to the next suspected area in the
table.
• If the problem still occurs even though there are no
malfunctions in any of the circuits, check the ECM and
replace it if necessary.
