AUTOMATIC TRANSMISSION FLUID ADJUSTMENT

PROCEDURE

1. BEFORE FILLING TRANSMISSION

   
   

   • The AA81E automatic transmission assembly requires Toyota Genuine ATF WS.

   • If the entire automatic transmission assembly, automatic transmission oil pan sub-assembly, drain plug, transmission valve body assembly and/or torque converter assembly have/has been replaced, proceed to the Fill Transmission procedure.

   • If the automatic transmission extension housing oil seal has been replaced and/or automatic transmission fluid leak has been repaired, proceed to the Check Fluid Temperature procedure.

2. FILL TRANSMISSION PAN 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 (make sure that the tilt angle from the front to rear of the vehicle is within +/- 1°).

   2. 

      *1	Refill Plug
      *a	Refill Hole

      Remove the refill plug and O-ring from the automatic transmission assembly.

   3. 

      Using a 5 mm hexagon socket wrench, remove the overflow plug and gasket from the automatic transmission assembly.

   4. 

      *a	Refill Hole
      *b	Overflow Plug Hole

      Add automatic transmission fluid to the refill hole until it flows out of the overflow plug hole.

      Note

      
      

      • Use Toyota Genuine ATF WS.

      • Be sure to add automatic transmission fluid slowly. If automatic transmission fluid is added quickly, the automatic transmission fluid may hit internal parts and bounce back, resulting in automatic transmission fluid coming out of the refill hole.

   5. 

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

   6. 

      Using a 5 mm hexagon socket wrench, temporarily install the overflow plug and gasket to the automatic transmission assembly.

      Tech Tips

      Reuse the old gasket as the overflow plug will be removed again.

6. CHECK 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 (make sure that the tilt angle from the front to rear of the vehicle is within +/- 1°).

   2. 

      Using a 5 mm hexagon socket wrench, remove the overflow plug and gasket from the automatic transmission assembly.

      CAUTION:

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

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

      
      

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

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

      Note

      If only a small amount of automatic transmission fluid (approximately 5 cc) comes out of the overflow plug hole, then only automatic transmission fluid remaining in the No. 1 transmission oil filler tube has come out. This is not considered to be overflow.

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

      
      

      1. 

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

         Tech Tips

         The automatic transmission fluid flow will not stop completely because the automatic transmission fluid continues to expand as its temperature increases.
