  3. ADJUST FLUID LEVEL AT HIGH TEMPERATURE


    1. Warm up the engine and turn the engine switch off.

    2. Check the automatic transmission fluid temperature.


      1. Connect the GTS to the DLC3 with the engine switch off.

      2. Turn the engine switch on (IG) and turn the GTS on.

        Note

        To reduce load, make sure that all electrical systems, such as the air conditioning and audio system, are off.

      3. Enter the following menus: Powertrain / Transmission / Data List / Engine Speed and A/T Oil Temperature No. 1.


        Powertrain > Transmission > Data List
        Tester Display
        Engine Speed
        A/T Oil Temperature No.1

        Note


        • If the automatic transmission fluid temperature tends to decrease when the automatic transmission fluid temperature is between 75 to 85°C (167 to 185°F) with the engine idling, make sure that automatic transmission fluid temperature is above 85°C (185°F) before starting work.

        • If the automatic transmission fluid temperature tends to increase when the automatic transmission fluid temperature is between 75 to 85°C (167 to 185°F) with the engine idling, make sure that automatic transmission fluid temperature is below 75°C (167°F) before starting work.

        • If the automatic transmission fluid temperature tends to not change when the automatic transmission fluid temperature is between 75 to 85°C (167 to 185°F) with the engine idling, make sure that automatic transmission fluid temperature is 80°C (176°F) before starting work.

    3. Depress and hold the brake pedal.

    4. Start the engine.

    5. Slowly move the shift position from P to M in the order of P → R → N → D → M to circulate the automatic transmission fluid through each part of the automatic transmission, and then move the shift position back to P.

      Tech Tips

      Keep the shift position in each position for approximately 3 seconds.

    6. Lift the vehicle.

      Note

      The automatic transmission fluid level cannot be measured accurately if the vehicle is not level. Make sure it is held level.

    7. B005SN0

      Remove the refill plug and gasket from the automatic transmission assembly.

      CAUTION:

      Make sure not to touch the high temperature parts such as the exhaust pipe, etc.

      *b SST (Tank Assembly)
      *c Hose of SST (Tank Assembly)
      *d Valve Handle (Upper Valve)
      *e Valve Handle (Lower Valve)

      Connect the hose of SST (tank assembly) to SST (vacuum regulator).

      SST
      09993-19025   ( 09993-20010 )

      Note

      Ensure both of the valves of SST (tank assembly) are closed by turning the valve handle (upper valve) and valve handle (lower valve) to the position shown in the illustration so they are perpendicular to the hoses.

    11. Connect a compressed air hose to SST (tank assembly).

      Note

      Do not apply 689 kPa (7.0 kgf/cm2, 100 psi) or more of compressed air to SST (tank assembly).

    12. B006A58

      Open the lower valve of SST (tank assembly) by turning the valve handle (lower valve) so it is in-line with the compressed air hose.

    13. B0069NY

      Open the upper valve of SST (tank assembly) by turning the valve handle (upper valve) so it is in-line with the hose of SST (tank assembly).

      Note

      B006B68

      • Make sure to turn the valve handle (upper valve) slowly.

      • Make sure the valve on the gauge of SST (vacuum regulator) stays between -10 to -20 kPa (-0.1 to -0.2 kgf/cm2, -1.5 to -2.9 psi).

      • If the value on the gauge of SST (vacuum regulator) exceeds -20 kPa (-0.2 kgf/cm2, -2.9 psi), make sure to turn the valve handle (upper valve) so it is perpendicular to the hose of SST (tank assembly) immediately, otherwise parts inside the automatic transmission assembly may be damaged.

      Tech Tips

      Vacuum will be applied to the automatic transmission assembly when both of the valves of SST (tank assembly) are opened to prevent automatic transmission fluid loss when removing/installing the overflow plug.

    14. B005V2B

      Using a 6 mm hexagon socket wrench, remove the overflow plug from the automatic transmission assembly.

      CAUTION:

      A small amount of HOT automatic transmission fluid may leak from the overflow plug hole during removal.

      Note

      The overflow plug and drain plug are located nearby one another. Make sure not to remove the incorrect plug.

      *2 Overflow Plug
      B006AHR Front of Vehicle

      Tech Tips

      *a SST (Overflow Level Gauge)
      *b SST (Adapter 12)

      Install SST (adapter 12) to SST (overflow level gauge) and then install SST (overflow level gauge) to the overflow plug hole by hand until it is fully seated against the automatic transmission oil pan sub-assembly.

      Note

      Ensure that the sliding tube of SST (overflow level gauge) is fully retracted into the housing of SST (overflow level gauge) before inserting it into the overflow plug hole.

      Tech Tips

      The level/measurement indicator on SST (overflow level gauge) will read 0 mm (0 in.) when the sliding tube of SST (overflow level gauge) is fully retracted.

    16. Adjust SST (overflow level gauge) to the specified measurement according to the table below and lock the sliding scale of SST (overflow level gauge) by tightening the thumb screw.

      Specified Measurement
      Specified measurement at automatic transmission fluid temperature 75 to 85°C (167 to 185°F)

      Engine Idle Speed (rpm)

      700 to 800

      		 46 to 49.9 mm (1.81 to 1.96 in.)

      Note

      Before proceeding with the inspection, make sure the automatic transmission fluid temperature is between 75 to 85°C (167 to 185°F) and the engine idle speed is within the specified range in the table above.

    17. B006BRJ

      Close the upper valve of SST (tank assembly) by turning the valve handle (upper valve) so it is perpendicular to the hose of SST (tank assembly).

      Note


      • Make sure to turn the valve handle (upper valve) slowly.

      • Make sure that the gauge of SST (vacuum regulator) reads 0 kPa (0 kgf/cm2, 0 psi).

      Tech Tips

      Vacuum that was applied to the automatic transmission assembly will not be applied when the valve handle (upper valve) is closed.

    18. Observe automatic transmission fluid flowing from the hose at the bottom of SST (overflow level gauge).


      • If the amount of automatic transmission fluid that comes out of SST (overflow level gauge) is large, proceed to step [#1].

    19. [#1] If the amount of automatic transmission fluid that comes out of SST (overflow level gauge) is large.


      1. Wait until the automatic transmission fluid flow slows and only drips come out.

        B0069JB

        Tech Tips

        The automatic transmission fluid flow will not stop completely because the automatic transmission fluid continues to expand as its temperature increases.

      2. B0069NY

        Open the upper valve of SST (tank assembly) by turning the valve handle (upper valve) so it is in-line with the hose of SST (tank assembly).

        *a SST (Overflow Level Gauge) *b Cloth

        Note


        • Use Toyota Genuine ATF WS.

        • Be sure to add automatic transmission fluid slowly. If automatic transmission fluid is added quickly, the automatic transmission fluid may hit internal parts and bounce back, resulting in automatic transmission fluid coming out of the refill hole.

        Tech Tips

        When pouring automatic transmission fluid into the refill hole, cover the area surrounding the refill hole with a cloth.

        If automatic transmission fluid adheres to the automatic transmission oil pan sub-assembly, it may be mistaken for an automatic transmission fluid leak.

      3. Wait until the automatic transmission fluid flow slows and only drips come out.
