AUTOMATIC TRANSAXLE FLUID ADJUSTMENT


  1. PRECAUTIONS AND WORK DESCRIPTION


    1. The U760E automatic transaxle does not have an oil filler tube and oil level gauge. When adding fluid, add fluid through the refill hole on the transaxle case. The fluid level can be adjusted by draining excess fluid (allowing excess fluid to overflow) through the No. 1 transmission oil filler tube of the oil pan.

      Tech Tips

      "Overflow" indicates the condition under which fluid comes out of the overflow plug hole.

    2. Before adjusting the fluid level, add the specified amount of fluid when the engine is cold and warm up the engine to circulate the fluid in the transaxle. Ensure that the fluid temperature is as specified and the engine is idling.

  3. BEFORE FILLING TRANSAXLE WITH FLUID


    1. Lift the vehicle.

      Note

      Set the vehicle on a lift so that the vehicle is kept level when it is lifted up.

    2. Remove the No. 2 engine under cover and front fender apron seal LH.

  4. PERFORM INITIAL FILLING

    Note

    If the transaxle is hot (ATF temperature is high), wait until the fluid temperature becomes the same as the ambient temperature before starting the following procedure. (Recommended ATF temperature: around 20°C [68°F])


    1. A01ELL0

      Remove the refill plug and gasket from the automatic transaxle assembly.

      Note

      After performing any of the following operations, it is not necessary to perform the initial filling procedure. Proceed to the Add Specified Amount of Fluid procedure.

      Operations that do not require initial filling

      • Disconnection of the oil cooler tube or oil cooler hose

      • Repair of fluid leakage due to a loose case plug, or a faulty plug gasket or O-ring

      • Replacement of a new transaxle with torque converter (filled fluid parts)

      1. Connect the GTS to the DLC3 with the ignition switch off.

      2. Turn the ignition switch to ON and turn the GTS on.

        Note

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

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

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

      5. 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 ignition switch off and wait until the fluid temperature drops below 45°C (113°F).

      6. Select the Active Test menu: Connect the TC and TE1 / ON.

        Tech Tips

        The indicator lights on the meter will not blink to indicate a DTC output when ''Connect the TC and TE1 / ON'' is performed.

      7. Depress and hold the brake pedal.

      8. Start the engine.

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

        Tech Tips

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

      10. A01EISX

        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 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 the fluid temperature detection mode.

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

        Tech Tips


        • When the 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 step where terminal TC is first turned off and perform the procedure again.

      12. Move the shift lever from N to P.

      13. Release the brake pedal.

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

        Note

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

        Tech Tips


        • Turning terminals TC and TE1 off activates the engine idle speed control mode.

        • In the engine idle speed control mode, engine idle speed control starts when the fluid temperature becomes 35°C (95°F) or more and the engine speed is maintained at approximately 800 rpm.

        • Even after terminals TC and TE1 are turned off, the fluid temperature detection mode is active until the ignition switch is turned off.

      15. A01EJFJE01

        Warm up the engine with the engine idling until the fluid temperature reaches the normal operating temperature (35 to 45°C [95 to 113°F]).

  7. ADJUST FLUID LEVEL

    CAUTION:

    Use caution while the engine is idling and the radiator fan is operating.


    1. Lift the vehicle.

    2. Adjust the fluid level.


      1. A01EM8H

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

        CAUTION:

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

      2. Check the amount of fluid that comes out of the overflow plug hole.

        Note

        If only a small amount of fluid (approximately 1 cc) comes out of the overflow plug hole, then only fluid remaining in the No. 1 transmission oil filler tube has come out. This condition is not considered as overflow, so it is necessary to add fluid.

      3. A01ELT4

        If the amount of fluid that comes out of the overflow plug hole is large, wait until the fluid flow slows and only drips come out.

      4. A01EJYU

        If no fluid comes out of the overflow plug hole, remove the refill plug and gasket. Then add transaxle fluid through the refill hole until fluid comes out of the overflow plug hole. Wait until the fluid flow slows and only drips come out.

        Note

        Use Toyota Genuine ATF WS.

      5. A01EJYP

        Check that the fluid flow has slowed and only drips come out.

        Tech Tips

        The fluid flow will not completely stop because the fluid expands as its temperature increases.
