AUTOMATIC TRANSAXLE FLUID ADJUSTMENT

Note

Precautions and work description


  • The U760E automatic transaxle does not have an oil filler tube and oil dipstick. 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.

  • 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.

  • The U760E automatic transaxle requires Toyota Genuine ATF WS.

  • The adjustment should be performed according to the procedures and notes.

Tech Tips

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

  1. BEFORE ADDING FLUID

    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. 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 2 bolts, clip and front fender apron seal LH.

  2. PERFORM INITIAL FILLING

    Note

    After performing either 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

    • Oil cooler tube or oil cooler hose removal/installation


    • Repair of oil seeping or oozing

  6. ADJUST FLUID LEVEL

    CAUTION:

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


    1. Lift the vehicle.

      Note

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

    2. A019NDI

      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.

    3. 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.

    4. If the fluid overflows


      1. A019OMG

        Wait until the fluid flow slows and only drips come out.

      2. A019N41

        Remove the refill plug and gasket.
