CONTINUOUSLY VARIABLE TRANSAXLE FLUID ADJUSTMENT

PROCEDURE

PRECAUTIONS AND WORK DESCRIPTION
1. The K411 continuously variable transaxle does not have an oil filler tube or dipstick. When adding fluid, add fluid through the refill hole in 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. When adding fluid, add the specified amount of fluid while the engine is cold. Then, warm up the engine to circulate the fluid in the transaxle and adjust the fluid level with the engine idling at the specified fluid temperature.
3. The K411 continuously variable transaxle requires Toyota Genuine CVT fluid TC.
4. When adjusting the fluid level, park the vehicle on level ground. Longitudinal tilt should be within +/- 1°.
5. When adjusting the fluid level, turn off all electrical devices, such as the air conditioning, headlights and electric fan, to reduce electrical load.
6. The fluid temperature in the text indicates "A/T Oil Temperature 1" displayed on the intelligent tester.
7. Perform the adjustment according to the following procedures and notes.
WORK FLOW
1. The adjustment should be performed according to the procedures referenced in the work flow below.
BEFORE FILLING TRANSAXLE WITH FLUID
Note

If the transaxle is hot (fluid temperature is high), wait until the fluid temperature becomes the same as the ambient temperature before starting the following procedure (recommended fluid temperature: approximately 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 (make sure the tilt angle from the front to rear of the vehicle is within +/- 1°).
2. Remove the engine under cover LH.

PERFORM INITIAL FILLING

Note

After performing any of the following operations, it is not necessary to perform the initial filling procedure. Proceed to the Add Specified Amount procedure (Step 5).

Operations that do not Require Initial Filling
Repair of fluid leak, etc. Removal and installation of the oil cooler.

Remove the refill plug and gasket from the continuously variable transaxle.
Using a 6 mm socket hexagon wrench, remove the overflow plug and gasket from the continuously variable transaxle.
Note
- If fluid comes out after removing the overflow plug, wait until the fluid flow slows and only drops come out.
- In this case, it is not necessary to perform the initial filling (Skip operation "d" and "e").

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 fluid temperature detection mode.

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 step where terminals are first connected and perform the procedure again.
Move the shift lever from N to P.
Release the brake pedal.
Disconnect the terminals of the DLC3.
1. When using the intelligent tester.
  - Enter the Active Test menus: Connect the TC and TE1 / OFF.
2. When not using the intelligent tester.
  - Remove SST from terminals 13 (TC) and 4 (CG).
  Note
  
  Make sure that the terminals 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 activates engine idle speed control mode.
  - In engine idle speed control mode, engine idle speed control starts when the fluid temperature reaches the specified temperature and the engine speed is maintained.
  - Even after the terminals are disconnected, fluid temperature detection mode is active until the ignition switch is turned off.

Adjust the fluid temperature to the normal operating temperature.

Check the fluid temperature by the D shift indicator.
Tech Tips
- In the fluid temperature detection mode, the D shift indicator comes on, goes off, or blinks depending on the fluid temperature.
- The fluid filling procedure should be performed when the D shift indicator is on (the fluid temperature is within the normal operating temperature range).

Adjust the fluid temperature.

If the D shift indicator is off [Below Normal Operating Temperature: 35°C (95°F) or less]: Warm up the engine with the engine idling in the engine idle speed control mode until the D shift indicator turns on.

If the D shift indicator is on [Normal Operating Temperature: 35 to 45°C (95 to 113°F)]: Immediately proceed to the Adjust Fluid Level procedure (Step 8).

If the D shift indicator blinks [Above Normal Operating Temperature: 45°C (113°F) or more]: Stop the engine and wait until the fluid temperature drops to 35°C (95°F) or less (the D shift indicator goes off). Then perform the Adjust Fluid Temperature procedure again from the beginning.

The Relationship between Normal Operating Temperature and the D Shift Indicator

	Below Normal Operating Temperature	Normal Operating Temperature	Above Normal Operating Temperature
Fluid Temperature ("A/T Oil Temperature 1" displayed on the intelligent tester)	35°C (95°F) or less	35 to 45°C (95 to 113°F)	45°C (113°F) or more
D Shift Indicator	Off	On	Blinks

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 (make sure the tilt angle from the front to rear of the vehicle is within +/-1°).
2. Using a 6 mm socket hexagon 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.
  - If the amount of fluid that comes out of the overflow plug hole is large, proceed to *1.
  - If no fluid comes out of the overflow plug hole, proceed to *2.
  Note
  
  If only a small amount of fluid (approximately 5 cc) comes out of the overflow plug hole, then only fluid remaining in the No. 1 transmission oil filler tube has come out. This is not considered to be overflow.
4. *2:
  
  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 drops come out.
  
  Note
  
  Use Toyota Genuine CVT fluid TC.
5. *1:
  
  If the amount of fluid that comes out of the overflow plug hole is large, wait until the fluid flow slows and only drops come out.
  
  Tech Tips
  
  The fluid flow will not completely stop because the fluid expands as its temperature increases.
6. Install a new gasket and the overflow plug.
  
  Torque:
  
  40 N*m { 408 kgf*cm, 30 ft.*lbf }
7. Install a new gasket and the refill plug.
  
  Torque:
  
  49 N*m { 500 kgf*cm, 36 ft.*lbf }
8. Lower the vehicle.
9. Turn the ignition switch off.
  
  Tech Tips
  
  Turning the ignition switch off exits fluid temperature detection mode.
10. Remove the intelligent tester from the DLC3 (when using the intelligent tester).
AFTER FILLING TRANSAXLE
