AUTOMATIC TRANSAXLE FLUID REPLACEMENT

When using the intelligent tester:

1. Connect the intelligent tester to the DLC3 with the engine switch off.

2. Turn the engine switch on (IG) and turn the intelligent tester on.

   Note

   To reduce load, make sure that all electrical systems, such as the air conditioning, lighting system, electric fan and audio system are off.

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

4. Select the Active Test item: Connect the TC and TE1 / ON.

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

6. Check the ATF temperature.

   Note

   
   

   • If the fluid temperature is below 45°C (113°F), proceed to the next step. (Recommended ATF temperature: 40°C [104°F] or less)

   • If the fluid temperature is 45°C (113°F) or more, turn the engine switch off and wait until the fluid temperature drops below 45°C (113°F).

7. Depress and hold the brake pedal.

8. Start the engine.

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

   Tech Tips

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

10. 

    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 less than 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 fluid temperature detection mode.

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

    Tech Tips

    
    

    • When 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 first step and perform the procedure again.

12. Move the shift lever from N to P.

13. Release the brake pedal.

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

    Note

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

    Tech Tips

    
    

    • Disconnecting terminals TC and TE1 activates engine idle speed control mode.

    • In 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 disconnected, fluid temperature detection mode is active until the engine switch is turned off.

    Warm up the engine with the engine idling until the fluid temperature reaches the fluid level adjustment temperature (40 to 45°C [104 to 113°F]).

    Below Fluid Level Adjustment Temperature	Fluid Level Adjustment Temperature	Above Fluid Level Adjustment Temperature
    40°C or less (104°F or less)	40 to 45°C (104 to 113°F)	45°C or more (113°F or more)

    Note

    
    

    • If the fluid temperature is within the fluid level adjustment temperature range, immediately proceed to the Adjust Fluid Level procedure.

    • If the fluid temperature is 45°C (113°F) or more, stop the engine and wait until the fluid temperature drops to 40°C (104°F) or less. Then perform the Adjust Fluid Temperature procedure again from the beginning.

    Tech Tips

    In fluid temperature detection mode, the D shift indicator comes on, goes off, or blinks depending on the fluid temperature.

Adjust the fluid level.

1. 

   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. 

   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. 

   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. 

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

   Tech Tips

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