PROCEDURE


  1. PRECAUTIONS AND WORK DESCRIPTION


    1. The U661F automatic transaxle assembly does not have an oil filler tube and oil level gauge. When adding automatic transaxle fluid, add automatic transaxle fluid through the refill hole on the rear transaxle cover sub-assembly. The automatic transaxle fluid level can be adjusted by draining excess automatic transaxle fluid (allowing excess fluid to overflow) through the No. 1 transmission oil filler tube of the automatic transaxle oil pan sub-assembly.

      Tech Tips

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

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

  9. ADJUST AUTOMATIC TRANSAXLE FLUID LEVEL

    CAUTION:

    Use caution while the engine is idling and the radiator fans are operating.


    1. Lift the vehicle.

      Note

      Set the vehicle on a lift so that the vehicle is kept level when it is lifted up (make sure the tilt angle from the front to rear of the vehicle is within +/- 1°).

    2. A01VWZI

      Using a 6 mm hexagon socket wrench, remove the overflow plug and gasket from the automatic transaxle oil pan sub-assembly.

      CAUTION:

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

    3. Check the amount of automatic transaxle fluid that comes out of the overflow plug hole.


      • If the amount of automatic transaxle fluid that comes out of the overflow plug hole is large, proceed to step [#1].

      • If no automatic transaxle fluid comes out of the overflow plug hole, proceed to step [#2].

      Note

      If only a small amount of automatic transaxle fluid (approximately 1 cc) comes out of the overflow plug hole, then only automatic transaxle 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 automatic transaxle fluid.

    4. If the amount of automatic transaxle fluid that comes out of the overflow plug hole is large. [#1]


      1. A01VWWH

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