Continuously Variable Transaxle Fluid Adjustment

The K111F continuously variable transaxle does not have an oil filler tube or oil level gauge. 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.

HINT:

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

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.

The K111F continuously variable transaxle requires Toyota Genuine CVT fluid TC.

When adjusting the fluid level, park the vehicle on level ground. Make sure that the longitudinal tilt of the vehicle is not more than 1°.

When adjusting the fluid level, turn off all electrical devices, such as the air conditioning, headlights and electric fan, to reduce electrical load.

The fluid temperature in the text indicates "A/T Oil Temperature 1" displayed on the intelligent tester.

Perform the adjustment according to the following procedures and notes.

The adjustment should be performed according to the procedures referenced in the work flow below.

Lift the vehicle.

NOTICE:

Set the vehicle on a lift so that the vehicle is kept level when it is lifted up (make sure the longitudinal tilt of the vehicle is not more than 1°).

Remove the No. 1 engine under cover and rear engine under cover LH.

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.

NOTICE:

1. If fluid comes out after removing the overflow plug, wait until the fluid flow slows and only drops come out.
   
2. If fluid comes out, it is not necessary to perform the initial filling procedure. After checking the tightening torque of the No. 1 transmission oil filler tube, temporarily install the overflow plug.
   

Using a 6 mm socket hexagon wrench, check that the No. 1 transmission oil filler tube is tightened to the specified torque.

Torque:

1.7 N*m{17 kgf*cm, 15 in.*lbf}

NOTICE:

If the No. 1 transmission oil filler tube is not tightened to the specified torque, the amount of fluid cannot be precisely adjusted.

HINT:

To check the torque of the No. 1 transmission oil filler tube, insert the hexagon socket into the overflow plug hole.

Perform initial filling.

1. Fill fluid into the refill hole until it flows out from the overflow plug hole.
   

   NOTICE:

   Use Toyota Genuine CVT fluid TC.

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

Temporarily install the overflow plug.

HINT:

Reuse the old gasket. The plug will be removed again to adjust the fluid level.

Remove the refill plug and gasket from the continuously variable transaxle (when initial filling is not performed).

Depress and hold the brake pedal.

Start the engine.

NOTICE:

Make sure that electrical systems, such as the air conditioning system, audio system and lighting system, are off.

Slowly move the shift lever from P to D, and then back to P (keep the shift lever in each position for approximately 3 seconds).

HINT:

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

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.

NOTICE:

Do not pause for more than 1.5 seconds.

HINT:

Performing this operation will cause the vehicle to enter fluid temperature detection mode.

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

HINT:

1. When fluid temperature detection mode is activated, the D shift indicator in the combination meter comes on for 2 seconds.
   
2. If the D shift indicator does not come on for 2 seconds, return to the step where the 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 following menus: Connect the TC and TE1 / OFF.
   

2. When not using the intelligent tester.
   Remove SST from terminals 13 (TC) and 4 (CG).
   

   NOTICE:

   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.

   HINT:

   1. Disconnecting the terminals activates engine idle speed control mode.
      
   2. 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.
      
   3. 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.

1. Check the fluid temperature by the D shift indicator.
   

   HINT:

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

2. Adjust the fluid temperature.
   

   1. If the D shift indicator is off [Below Normal Operating Temperature: 30°C (86°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.
      
   1. If the D shift indicator is on [Normal Operating Temperature: 30 to 40°C (86 to 104°F)]: Immediately proceed to the Adjust Fluid Level procedure (Step 7).
      
   1. If the D shift indicator blinks [Above Normal Operating Temperature: 40°C (104°F) or higher]: Stop the engine and wait until the fluid temperature drops to 30°C (86°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)	30°C or less (86°F or less)	30 to 40°C (86 to 104°F)	40°C or higher (104°F or higher)
   D Shift Indicator	Off	On	Blinks

Lift the vehicle.

NOTICE:

Set the vehicle on a lift so that the vehicle is kept level when it is lifted up (make sure the longitudinal tilt of the vehicle is not more than 1°).

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.

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

1. If the amount of fluid that comes out of the overflow plug hole is large, proceed to *1.
   
2. If no fluid comes out of the overflow plug hole, proceed to *2.
   

NOTICE:

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.

*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.

NOTICE:

Use Toyota Genuine CVT fluid TC.

*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.

HINT:

The fluid flow will not completely stop because the fluid expands as its temperature increases.
