CONTINUOUSLY VARIABLE TRANSAXLE FLUID ADJUSTMENT

Note


  • This transaxle requires Toyota Genuine CVT fluid FE.

  • Make sure that the vehicle is level when inspecting the fluid level.

    (The front-to-rear inclination angle must be within +/- 1° from horizontal.)

  • Allow the fluid to cool to room temperature before performing any of these procedures.


  1. ADD CONTINUOUSLY VARIABLE TRANSAXLE FLUID

    Tech Tips

    Refer to the following diagram when adding fluid.

    A011A5IE02

    1. When adding fluid (large fill volume) *1


      1. Be sure that the vehicle remains level and lift the vehicle.

      2. A0118LF

        Using a 6 mm hexagon socket wrench, remove the overflow plug and the gasket.

      3. A0117KC

        Using a 6 mm hexagon socket wrench, check that the No. 1 transmission oil filler tube is tightened to the specified torque.

        Torque:
        0.8 N*m  { 8 kgf*cm, 7 in.*lbf }

        Note

        If the No. 1 transmission oil filler tube is not tightened to the specified torque, then the fluid level cannot be adjusted correctly.

      4. A011AAZ

        Remove the refill plug and the gasket.

      5. A011BTH

        Add fluid into the refill hole until it flows out from the overflow hole.

        Note

        Use Toyota Genuine CVT fluid FE.

      6. Wait until the steady flow slows to a trickle, install the gasket, and temporarily tighten the overflow plug with a 6 mm hexagon socket wrench.

        A011BDH

        Tech Tips

        Because the overflow plug will be removed again, the gasket can be reused at this time.

      7. A011AL7

        Fill the specified volume of fluid into the refill hole.

        Note

        The fill amount varies depending on the procedures being completed.

        Reference Capacity
        Related Procedure Fill Volume
        Transaxle replacement (with a new torque converter) 1.4 liters (1.5 US qts, 1.2 Imp. qts)

      8. A011AAZ

        Install the gasket and temporarily tighten the refill plug.

        Tech Tips

        Because the refill plug will be removed again, the gasket can be reused at this time.

      9. Lower the vehicle.

    2. When refilling (small fill volume) *2


      1. A011AAZ

        Be sure that the vehicle remains level and lift the vehicle.

      2. Remove the refill plug and the gasket.

      3. A011AL7

        Fill the specified volume of fluid into the refill hole.

        Reference Capacity
        Related Procedure Fill Volume
        Oil cooler removal/installation or replacement 0.4 liters (0.4 US qts, 0.4 Imp. qts)
        Repair of oil seeping or oozing 0.4 liters (0.4 US qts, 0.4 Imp. qts)
      4. A011AAZ

        Install the gasket and temporarily tighten the refill plug.

        Tech Tips

        Because the refill plug will be removed again, the gasket can be reused at this time.

      5. Lower the vehicle.

  2. FLUID TEMPERATURE CHECK

    Note

    The fluid temperature can be confirmed by checking the indicator light in the meter or by using the intelligent tester. When using the intelligent tester, it is necessary to change to temperature detection mode in order to idle the vehicle appropriately.


    1. When using the intelligent tester:


      1. Turn the ignition switch off.

      2. Connect the intelligent tester to the DLC3.

      3. Turn the ignition switch to ON.

      4. Turn the intelligent tester on.

      5. Enter the following menus: Powertrain / Engine and ECT / Data List / A/T Oil Temperature 1.

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

    2. When not using the intelligent tester:


      1. A01191HE67
        Text in Illustration
        *1 DLC3

        Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

        SST
        09843-18040

    3. Start the engine.

      Note

      Check that electrical systems such as the air conditioning system, audio system and lighting system are off.

      Tech Tips

      Indicator lights of the meter blink to output DTCs when terminals 13 (TC) and 4 (CG) are connected.

    4. Slowly move the shift lever from P to B and back to P again.

      Tech Tips

      Hold the shift lever in each position for approximately 3 seconds.

    5. A0119OX

      Move the shift lever to D, and then continuously 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.

      Standard condition
      The indicator light (D) remains illuminated for 2 seconds and then turns off.

      Tech Tips

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

    6. Return the shift lever to P.

    7. When using the intelligent tester:


      1. According to the display on the intelligent tester, perform the Active Test "Connect the TC and TE1 / OFF".

    8. When not using the intelligent tester:


      1. Remove SST from terminals 13 (TC) and 4 (CG).

    9. The indicator light (D) remains off, illuminates, or blinks depending on the fluid temperature.

      Indicator Light (D)
      Remains Off Illuminates Blinks
      Below 35°C (95°F)

      35°C (95°F) to

      45°C (113°F)

      		 45°C (113°F) or higher
      Below proper temperature Proper temperature range Above proper temperature

    10. If the indicator remains off or illuminates, perform the "Fluid Level Check".

      Tech Tips

      If the light is blinking, stop the engine, wait for the fluid temperature to decrease, and repeat the procedure from "Fluid Temperature Check".

  3. FLUID LEVEL CHECK


    1. A0117VD

      Idle the engine to warm it up, and ensure that the fluid temperature is correct.

    2. Lift the vehicle immediately after the indicator light (D) illuminates.

      Note

      Adjust the fluid level while the indicator light (D) is illuminated.

    3. A0118LF

      Using a 6 mm hexagon socket wrench, remove the overflow plug and the gasket, and then check the fluid condition.

      Tech Tips


      • Check that the fluid flows out from the overflow tube.

      • If the volume of fluid that flows out is small, it is possible that fluid was remaining in the No. 1 transmission oil filler tube (approximately 5 cc (0.3 cu in.)), so assume that there was no overflow.

    4. If the fluid overflows:


      1. Wait until the steady flow slows to a trickle, and then use a 6 mm hexagon socket wrench to install a new gasket and tighten the overflow plug.

        A011BDH
        Torque:
        40 N*m  { 408 kgf*cm, 30 ft.*lbf }
      2. A011AAZ

        Replace the refill plug with a new gasket and tighten the refill plug.

        Torque:
        49 N*m  { 500 kgf*cm, 36 ft.*lbf }

    5. If the fluid does not overflow:


      1. A011AAZ

        Remove the refill plug and the gasket.

      2. A011BTH

        Add fluid into the refill hole until it flows out from the overflow hole.

        Note

        Use Toyota Genuine CVT fluid FE.

      3. Wait until the steady flow slows to a trickle, and then install a new gasket and tighten the overflow plug.

        A011BDH
        Torque:
        40 N*m  { 408 kgf*cm, 30 ft.*lbf }
      4. A011AAZ

        Install a new gasket and fully tighten the refill plug.

        Torque:
        49 N*m  { 500 kgf*cm, 36 ft.*lbf }

    6. Lower the vehicle.

    7. When using the intelligent tester:


      1. Turn the ignition switch off and disconnect the intelligent tester.

    8. When not using the intelligent tester:


      1. Turn the ignition switch off.

  4. INSPECT FOR CONTINUOUSLY VARIABLE TRANSAXLE FLUID LEAK


    1. Clean the area and check for fluid leaks.
