HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
CAUTION:
The line pressure test should always be carried out in pairs. One technician should observe the conditions of the wheels and wheel stoppers from outside the vehicle while the other is performing the test.
NOTICE:
(1) Warm up the ATF (Automatic Transmission Fluid).
(2) Turn the ignition switch off.
(3) Lift the vehicle up.
(4) Remove the test plug from the transmission case and connect SST.
SST: 09992-00095
09992-00231
09992-00271
(5) Lower the vehicle.
(6) Fully apply the parking brake and chock the 4 wheels.
(7) Start the engine and check the idling speed.
(8) Keep your left foot pressed firmly on the brake pedal and move the shift lever to D.
(9) Measure the line pressure when the engine is idling.
(10) Fully depress the accelerator pedal with your right foot. Quickly read the highest line pressure when the engine speed reaches stall speed.
(11) In the same manner, perform the test with the shift lever in R.
