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
right side and connect SST.
SST 09992-00095 (09992-00231, 09992-00271)
(c) Fully apply the parking brake and chock the 4
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
