  4. CHECK FLUID TEMPERATURE

    Note

    The automatic transmission fluid temperature can be confirmed by checking the D shift indicator on the combination meter or using the GTS. When not using the GTS, it is necessary to enter automatic transmission fluid temperature detection mode.


    1. When using the GTS:

      Tech Tips

      The actual ATF temperature can be checked on the Data List using the GTS.


      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, lighting system, electric fan and audio system are off.

      3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Connect the TC and TE1.

      4. Select the Active Test item: Connect the TC and TE1 / ON.

      5. Select the Data List menu: A/T Oil Temperature 1.

      6. Check the ATF temperature.

        Note


        • If the fluid temperature is below 45°C (113°F), proceed to the next step. (Recommended ATF temperature: 35°C (95°F) or less)

        • If the fluid temperature is 45°C (113°F) or more, turn the engine switch off and wait until the fluid temperature drops below 45°C (113°F).

      7. Depress and hold the brake pedal.

      8. Start the engine.

        Note

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

      9. Slowly move the shift lever from P to S, then move the shift lever to P.

        Tech Tips

        Slowly move the shift lever to circulate the automatic transmission fluid through each part of the automatic transmission assembly.

      10. While observing the D shift indicator on the combination meter, move the shift lever back and forth between N and D at an interval of less than 1.5 seconds for 6 seconds or more.

        Note

        Do not pause for more than 1.5 seconds.

        Tech Tips

        Performing this operation will cause the vehicle to enter automatic transmission fluid temperature detection mode.

      11. B001VVO

        Check that the D shift indicator comes on for 2 seconds.

        Tech Tips


        • When fluid temperature detection mode is activated, the D shift indicator on the combination meter comes on for 2 seconds.

        • If the D shift indicator does not come on for 2 seconds, return to the first step and perform the procedure again.

      12. Move the shift lever from N to P.

      13. Release the brake pedal.

      14. Select the Active Test item: Connect the TC and TE1 / OFF.

        Note

        Be sure that terminals TC and TE1 are not connected. If the terminals are connected, the fluid level cannot be precisely adjusted due to fluctuations in engine speed.

        Tech Tips


        • Disconnecting terminals TC and TE1 activates engine idle speed control mode.

        • Even after terminals TC and TE1 are disconnected, automatic transmission fluid temperature detection mode will be active until the engine switch off.

    2. When not using the GTS:

        Note

        Be sure that terminals TC and CG are not connected. If the terminals are connected, the automatic transmission fluid level cannot be precisely adjusted due to fluctuations in engine speed.

        Tech Tips


        • Disconnecting terminals TC and CG activates the engine idle speed control mode.

        • Even after terminals TC and CG are disconnected, automatic transmission fluid temperature detection mode will be active until the engine switch off.

    3. Allow the engine to idle until the automatic transmission fluid temperature reaches 35 to 45°C (95 to 113°F).

    4. The D shift indicator will come on again when the fluid temperature reaches 35°C (95°F) and will blink when it exceeds 45°C (113°F).

      Tech Tips

      Adjust the transmission fluid level when the "D" shift position indicator is illuminated.


      1. If the P shift position indicator is not illuminated, idle the engine to warm it up until the P shift position indicator illuminates.

      2. If the P shift position indicator is illuminated, immediately begin to adjust the automatic transmission fluid level.

      3. If the P shift position indicator is blinking, stop the engine to cool the automatic transmission fluid. Once the automatic transmission fluid temperature drops to the appropriate level, perform the automatic transmission fluid level adjustment procedure again.

  5. CHECK FLUID LEVEL


    1. Lift the vehicle.

      Note

      Set the vehicle on a lift so that the vehicle is kept level when it is lifted up (make sure that the tilt angle from the front to rear of the vehicle is within +/-1°).

    2. B001ZZC

      Using a 5 mm hexagon socket wrench, remove the overflow plug and gasket from the automatic transmission assembly.

      CAUTION:

      Be careful as the automatic transmission fluid coming out of the overflow hole is hot.

    3. Check the amount of automatic transmission fluid that comes out of the overflow hole.


      • If the amount of automatic transmission fluid that comes out of the overflow hole is large, proceed to step [*1].

      • If no automatic transmission fluid comes out of the overflow hole, proceed to step [*2].

      Note

      If only a small amount of automatic transmission fluid (approximately 5 cc) comes out of the overflow hole, then only automatic transmission fluid remaining in the overflow tube of overflow hole has come out. This is not considered to be overflow.

    4. B001X7P

      If the amount of automatic transmission fluid that comes out of the overflow hole is large, wait until the automatic transmission fluid flow slows and only drips come out. [*1]

      Tech Tips

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

    5. B001ZZ6C01
      *a Refill Hole
      *b Overflow Hole

      If no automatic transmission fluid comes out of the overflow hole, remove the refill plug and O-ring. Then add automatic transmission fluid to the refill hole until it flows out of the overflow hole. Wait until the automatic transmission fluid flow slows and only drips come out. [*2]

      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.
