Adjustment [08/2013 - ]: Procedure

PRECAUTIONS AND WORK DESCRIPTION

The K313 continuously variable transaxle assembly does not have an oil filler tube or oil level gauge. When adding fluid, add fluid through the refill hole in the continuously variable transaxle assembly. 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 transaxle oil (CVT) pan sub-assembly.
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 assembly is cold. Then, warm up the engine assembly to circulate the fluid in the continuously variable transaxle assembly and adjust the fluid level with the engine idling at the specified fluid temperature.
The K313 continuously variable transaxle assembly requires Toyota Genuine CVT fluid FE.
When adjusting the fluid level, park the vehicle on level ground (make sure that the tilt angle from the front to rear of the vehicle is within +/-1°).
When adjusting the fluid level, turn off all electrical systems, such as the air conditioning, lighting system, electric fan and audio system, to reduce load.
The fluid temperature shown in the text is "A/T Oil Temperature 1" displayed on the Techstream.

Fluid level adjustment should be performed according to the following procedure and notes.

If the D shift indicator does not come on for 2 seconds, return to the first step and perform the procedure again.

Move the shift lever to P.
Release the brake pedal.
Disconnect the terminals of the DLC3.
1. When using the Techstream:
  - According to the display on the Techstream, perform the Active Test "Connect the TC and TE1 / OFF".
2. When not using the Techstream:
  - Remove SST from terminals 13 (TC) and 4 (CG).
  NOTE:
  Make sure that terminals 13 (TC) and 4 (CG) are not connected. If the terminals are connected, the fluid level cannot be precisely adjusted due to fluctuations in engine speed.
  
  HINT:
  - Disconnecting the 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 value and the engine speed is maintained.
  - Even after the terminals are disconnected, fluid temperature detection mode remains active until the ignition switch is turned off.

Adjust the fluid temperature to the fluid level adjustment temperature.

Check the fluid temperature by monitoring the D shift indicator.
HINT:
- In 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 fluid level adjustment temperature range).

Adjust the fluid temperature.

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

If the D shift indicator is on [Fluid Level Adjustment Temperature: 35 to 45°C (95 to 113°F)]: Immediately proceed to Adjust Fluid Level (Step 7).

If the D shift indicator is blinking [Above Fluid Level Adjustment 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.

ADJUST FLUID LEVEL

WARNING:

Use caution while the engine assembly is idling and the radiator fan is operating.

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°).

Using a 6 mm hexagon socket wrench, remove the overflow plug and gasket from the continuously variable transaxle assembly.

WARNING:

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.
- 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.

*1:

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.

HINT:

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

*2:

If no fluid comes out of the overflow plug hole, remove the refill plug and gasket. Then add 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 CVT fluid FE.
