AUTOMATIC TRANSMISSION FLUID ADJUSTMENT

CAUTION / NOTICE / HINT

B001H92E01

Note


  • This transmission requires Toyota Genuine ATF WS.

  • After servicing the transmission, you must follow the ATF adjustment procedure.

  • Maintain the vehicle in a horizontal position while adjusting the fluid level.

PROCEDURE


  1. BEFORE FILLING TRANSMISSION


    • When you have replaced the entire transmission, transmission pan, drain plug, valve body and/or torque converter, proceed to the "Transmission Fill" procedures.

    • When you have replaced the transmission hose and/ or output shaft oil seal, proceed to the "Fluid Temperature Check" procedures.

      *1 Refill Plug
      *2 Overflow Plug
      *3 Refill Hole

      Remove the refill plug and overflow plug.

    2. B001G9JE02

      *1 Overflow Tube
      *a Specified Fluid Level

      Fill the transmission through the refill hole until fluid begins to trickle out of the overflow tube.

    3. Reinstall the overflow plug.

    4. Fill the transmission with the amount of fluid listed in the table below.

      Reference Capacity
      Repair Fill Amount
      Transmission pan and drain plug removal 1.7 liters (1.8 US qts, 1.5 Imp. qts)
      Transmission valve body removal 4.3 liters (4.5 US qts, 3.8 Imp. qts)
      Torque converter removal 5.4 liters (5.7 US qts, 4.8 Imp. qts)

    5. Install the refill plug.

      Tech Tips

      If you cannot fill the listed amount of fluid, perform the following:


      1. Start the engine and idle it.

        Note

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

      2. Move the shift lever through the entire gear range to circulate the fluid.

      3. Wait for 30 seconds with the engine idling.

      4. Stop the engine.

      5. Remove the refill plug.

      6. Fill the transmission with the remaining fluid until the amount in the table has been filled.

      7. Install the refill plug.

  3. FLUID TEMPERATURE CHECK

    Note

    The ATF temperature can be confirmed by using the GTS.


    1. Turn the ignition switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON.

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

    5. Check the ATF temperature.

      Note

      If the ATF temperature is higher than 45°C (113°F), turn the ignition switch off and wait until the fluid temperature drops to below 40°C (104°F).

  4. FLUID LEVEL CHECK

    CAUTION:


    • It is necessary to change to temperature detection mode in order to idle the vehicle appropriately.

    • The ATF temperature must be between 40 and 45°C (104 and 113°F) to accurately check the fluid level.


    1. When using the GTS:

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

      *a Front view of DLC3

      When not using the GTS:

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

      SST
      09843-18040
      Standard condition
      Indicator lights in the combination meter blink.

    3. Start the engine and idle it.

      Note

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

    4. Slowly move the shift lever from P to S, and then change the gear from 1st to 5th. Then return the shift lever to P.

      Tech Tips

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

    5. B001E6FC01
      *A w/o Multi-Information Display
      *B w/ Multi-Information Display

      Move the shift lever to D, and quickly move it back and forth between N and D (once within 1.5 seconds) for at least 6 seconds. This will activate the fluid temperature detection mode.

      Standard condition
      Indicator light [D] remains illuminated for 2 seconds and then turns off.

    6. When using the GTS:

      Return the shift lever to P and terminate the Active Test on the GTS.

    7. When not using the GTS:

      Return the shift lever to P and disconnect SST from the DLC3.

    8. Allow the engine to idle until the fluid temperature reaches 40 to 45°C (104 to 113°F).

      Tech Tips

      The indicator [D] will come on again when the fluid temperature reaches 40°C (104°F) and will blink if it is higher than 45°C (113°F).

      Indicator [D] Indication of ATF Temperature
      Below 40°C (104°F) 40 to 45°C (104 to 113°F) Higher than 45°C (113°F)
      Turn off Turn on Blinking

      *1 Overflow Tube
      *a Specified Fluid Level

      Remove the overflow plug and gasket with the engine idling.

    10. Wait until the overflow slows to a trickle.

      Note

      If the fluid does not overflow, perform the following:


      1. Remove the refill plug and gasket.

      2. Refill the transmission through the refill hole until fluid begins to trickle out of the overflow tube.

      3. Wait until the overflow slows to a trickle.

    11. Install a new gasket and the overflow plug.

      Torque:
      20 N*m  { 204 kgf*cm, 15 ft.*lbf }

    12. Install a new gasket and the refill plug.

      Torque:
      37 N*m  { 379 kgf*cm, 27 ft.*lbf }

  5. COMPLETE


    1. Turn the ignition switch off.

    2. When using the GTS:

      Disconnect the GTS from the DLC3.

    3. Inspect for automatic transmission fluid leaks.

  6. ATF THERMAL DEGRADATION ESTIMATE RESET

    Tech Tips

    Approximately 50% or more of the automatic transmission fluid has been replaced during a repair of the transmission or a similar operation.
