NOTICE:
  1. This transmission requires Toyota Genuine CVT Fluid TC.
  2. Make sure that the vehicle is level when inspecting the fluid level.
    (The front-to-rear inclination angle must be within +/- 1° from horizontal.)
  3. Allow the fluid to cool to room temperature before performing any of these procedures.



1. ADD CVT FLUID

HINT:
Refer to the following diagram when adding fluid.

C196797E01



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



      C195107

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

    2. Use a socket hexagon wrench (6 mm) to remove the drain plug and gasket.



      3. C196794E01

    3. Use a socket hexagon wrench (6 mm) to check that the No. 1 transmission oil filler tube is tightened to the specified torque.

      *1
      		No. 1 Transmission Oil Filler Tube

      Torque:
      0.8 N*m{ 8.2 kgf*cm , 7 in.*lbf }

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



      4. C195108

    4. Remove the refill plug and gasket.



      5. C195110

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

      NOTICE:
      This transmission requires Toyota Genuine CVT Fluid TC.



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

      HINT:
      Because the drain plug will be removed again, the gasket can be reused at this time.

    7. Fill the specified volume of transmission fluid into the refill hole.

      NOTICE:
      The fill amount varies depending on the procedures being completed.

      		0.4 liters (0.42 US qts, 0.35 Imp. qts)

    4. Install the gasket and temporarily tighten the refill plug.

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

    5. Lower the vehicle.



2. FLUID TEMPERATURE CHECK

NOTICE:
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 tester on.

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

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



  1. When not using the intelligent tester



      C101492J18

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

      SST
      09843-18040  

  1. Start the engine.

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

    HINT:
    Indicator lights of the meter blink to output DTCs when terminals TC and CG are connected.

  1. Slowly move the shift lever from P to B (from P to D for multi-mode automatic transmission) and back to P again.

    HINT:
    Hold the shift lever in each position for about 3 seconds.



    C197456

  1. Move the shift lever to D, and then continuously move the shift lever back and forth between N and D at a rate of 1 shift/1.5 seconds or faster for 6 seconds or more. This will activate the fluid temperature detection mode.

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

  1. Return the shift lever to P.

  1. 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

  1. If the indicator remains off or illuminates, disconnect the TC terminal and perform the "Fluid Level Check".

    NOTICE:
    1. If the TC terminal is not OFF (open), accurate fluid level adjustment is not possible, so be sure to disconnect this terminal.
    2. If the TC terminal is not OFF (open), in some cases, the fluid temperature reading will immediately exceed the proper temperature for adjustment.
    3. 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


    C195113

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

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

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

  1. Use a socket hexagon wrench (6 mm) to remove the drain plug and gasket, and then check the fluid condition.

    HINT:
    1. Check that the fluid flows out from the overflow tube.
    2. If the volume of fluid that flows out is small, it is possible that fluid was remaining in the tube (about 5 cc (0.30512 cu in.)), so assume that there was no overflow.

  1. If the fluid overflows

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

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

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

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

  1. If the fluid does not overflow

    1. Remove the refill plug and gasket.

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

      NOTICE:
      This transmission requires Toyota Genuine CVT Fluid TC.

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

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

    4. Install a new gasket and fully tighten the refill plug.

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

  1. Lower the vehicle.

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



4. INSPECT FOR CONTINUOUSLY VARIABLE TRANSAXLE FLUID LEAK

  1. Clean the area and check for fluid leaks.
