15. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation fluid temperature 70
to 80°C (158 to 176°F).
The line pressure test should always be carried out in
pairs. One technician should observe the conditions
of wheels or wheel stoppers outside the vehicle while
the other is doing the test.
Be careful to prevent SST's hose from interfering with
the exhaust pipe.
This check must be conducted after checking and ad-
justing engine.
Perform under condition that A/C is OFF.
When conducting stall test, do not continue more
than 10 seconds.
(1) Warm up the ATF.
(2) Remove the test plug on the transmission case cen-
ter right side and connect SST.

(3) Fully apply the parking brake and chock the 4
wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressing firmly on the brake ped-
al and shift into D position.
(6) Measure the line pressure when the engine is idling.
(7) Depress the accelerator pedal all the way down.
Quickly read the highest line pressure when engine
speed reaches stall speed.
(8) In the same manner, do the test in R position.
