Automatic Transmission System (For 1Vd-Ftv With Dpf) -- Hydraulic Test



PERFORM HYDRAULIC TEST


  1. 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 chocks outside the vehicle while the other is performing the test.
    NOTICE:
    1. Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature: 50 to 80°C (122 to 176°F).
    2. Be careful to prevent SST hose from interfering with the exhaust pipe.
    3. This check must be conducted after checking and adjusting the engine.
    4. Perform the test with the A/C turned off.
    5. When conducting the stall test, do not continue for more than 5 seconds.

    1. Warm up the ATF (Automatic Transmission Fluid).

    2. Turn the engine switch off.

    3. Lift the vehicle up.

    4. Remove the test plug on the transmission case center right side and connect 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. Fully depress the accelerator pedal with your right foot. Quickly read the highest line pressure when the engine speed reaches the stall speed.

    10. In the same manner, perform the test with the shift lever in R.
