Automatic Transmission Fluid -- Adjustment



1. BEFORE REFILL TRANSMISSION
  1. This transmission requires Toyota Genuine ATF WS transmission fluid.
  2. After servicing the transmission, you must refill the transmission with the correct amount of fluid.
  3. Maintain the vehicle in a horizontal position while adjusting the fluid level.
  4. If the transmission pan, drain plug, valve body or torque converter is replaced, proceed to the "transmission pan fill" procedures.
  5. If the transmission hose or output shaft oil seal is replaced, remove the refill plug and proceed to the "transmission fill" procedures.
  6. If the entire transmission is replaced, proceed to the "fluid circulation" procedures.
    HINT:
    New transmissions are already filled with transmission fluid.


2. TRANSMISSION PAN FILL

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

  1. Reinstall the overflow plug.



3. TRANSMISSION FILL

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

  1. Reinstall the refill plug to prevent the fluid from splashing.

    Standard 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 (4.54 US qts, 3.78 Imp. qts)
    Torque converter removal
    		5.4 liters (5.71 US qts, 4.75 Imp. qts)
    HINT:
    If the amount of fluid listed in the table cannot be added, perform the next step.

  1. When the amount of fluid listed in table cannot be added:

    1. Install the refill plug.

    2. Allow the engine to idle with the air conditioning OFF.

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

    4. Wait for 30 seconds with the engine idling.

    5. Stop the engine.

    6. Remove the refill plug and add fluid.

    7. Reinstall the refill plug.



4. FLUID CIRCULATION

  1. Allow the engine to idle with the air conditioning OFF.

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

  1. Allow the engine to idle until the fluid temperature reaches 36°C (97°F). Proceed to the step to the next to check fluid temperature.

    HINT:
    The fluid temperature should be less than 30°C (86°F) before starting the engine.


5. FLUID TEMPERATURE CHECK

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

    09843-18040

  1. Depress and hold the brake pedal.

  1. Start the engine.

    NOTICE:
    Check that electrical systems, such as the air conditioning system, audio system and lighting system, are off.
    HINT:
    The indicator lights in the meter blink to indicate output DTCs when terminals TC and CG are connected.

  1. Slowly move the shift lever from P to D, and then back to P.

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

  1. Move the shift lever back and forth between N and D at 1.5 second intervals for 6 seconds.

  1. The A/T OIL TEMP indicator turns on for 2 seconds when the combination meter starts to detect the fluid temperature.

  1. The A/T OIL TEMP indicator turns on again when the fluid temperature reaches 36°C (97°F) and blinks when it exceeds 46°C (115°F).



6. FLUID LEVEL CHECK

NOTICE:
The ATF temperature must be between 36° (97°F) and 46°C (115°F) to accurately check the fluid level.

  1. Remove the overflow plug with the engine idling.

  1. Check that the fluid comes out of the overflow tube.
    If fluid does not come out, proceed to the "Transmission Refill" procedures.
    If fluid comes out, wait until the overflow slows to a trickle and proceed to the "Complete" procedures.



7. TRANSMISSION REFILL

  1. Remove the overflow plug.

  1. Remove the refill plug.

  1. Add ATF into the refill hole until ATF flows from the overflow tube.

  1. Wait until the overflow slows to a trickle and proceed to the "Complete" procedures.



8. COMPLETE

  1. Install a new gasket and the overflow plug.

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

  1. Stop the engine.

  1. Install a new gasket and the refill plug.

    Torque:
    37 N*m{377 kgf*cm, 27 ft.*lbf}
