On-Vehicle Inspection

WARNING: This page is about a different variant/trim than selected.

PRECAUTIONS AND WORK DESCRIPTION
- The U660E automatic transaxle does not have an oil filler tube and oil level gauge. When adding fluid, add fluid through the refill hole on the transaxle case. The fluid level can be adjusted by draining excess fluid (allowing excess fluid to overflow) through the overflow tube of the oil pan.
  HINT:
  
  "Overflow" indicates the condition under which fluid comes out of the overflow plug hole.
- Before adjusting the fluid level, add the specified amount of fluid when the engine is cold and warm up the engine to circulate the fluid in the transaxle. Ensure that the fluid temperature is as specified and the engine is idling.
- The U660E automatic transaxle requires Toyota Genuine ATF WS.
- The adjustment should be performed according to the prcedures and notes.
WORK FLOW
1. The adjustment should be performed according to the procedures referring to the work flow below.
BEFORE FILLING TRANSAXLE WITH FLUID
1. Lift the vehicle.
  NOTICE:
  
  Set the vehicle on a lift so that the vehicle is kept level when it is lifted up.
2. Remove the engine under covers RH, and LH and fender apron seal LH.

PERFORM INITIAL FILLING

NOTICE:

If the transaxle is hot (AT fluid temperature is high), wait until the fluid temperature becomes the same as the ambient temperature before starting the following procedure. (Recommended ATF temperature: around 20°c [68°f])

Remove the refill plug and gasket from the automatic transaxle.

NOTICE:

After performing any of the following operations, it is not necessary to perform the initial filling procedure. Proceed to the next "ADD SPECIFIED AMOUNT OF FLUID" procedure.

Operation that does not require initial filling

Operation that does not require initial filling
Disconnection the oil cooler tube or oil cooler hose Repair of fluid leakage due to a loose case plug, or a faulty plug gasket or O-ring Replacement of a new transaxle with torque converter (filled fluid parts)

Using a 6 mm socket hexagon wrench, remove the overflow plug and gasket from the automatic transaxle.
NOTICE:
- If ATF comes out after removing the overflow plug, wait until the fluid flow slows and only drips come out.
- If ATF comes out, it is not necessary to perform the initial filling procedure. After checking the tightening torque of the overflow tube, temporarily tighten the overflow plug.

Using a 6 mm socket hexagon wrench, check that the overflow tube is tightened to the specified torque.
Torque: 1.7 N*m (17 kgf*cm, 15 ft.*lbf)

NOTICE:

If the transmission overflow tube is not tightened to the specified torque, the amount of fluid cannot be precisely adjusted.

HINT:

To check the torque of the overflow tube, insert the hexagon socket into the overflow hole.

ADJUST FLUID TEMPERATURE

When using the Techstream:

HINT:

The actual ATF temperature can be checked on the data list using the Techstream.

Connect the Techstream to the DLC3 with the iginition switch off.
Turn the ignition switch to ON and turn the Techstream main switch ON.
NOTICE:

Check that electrical systems such as the air conditioning system, audio system and lighting system are off.
Enter the following menus: Powertrain / Engine / Active test / Connect the TC and TE1.
Select the data list menu: A/T Oil Temperature 1.
Check A/T Oil Temperature 1.
NOTICE:
- If the fluid temperature is below 45°C (113°F), proceed tot he next step (Recommended ATF temperature 40°C [104°F] or less)
- If the fluid temperature is 45°C (113°F) or more, turn the ignition switch off and wait until the fluid temperature drops below 45°C (113°F).
Push the active test menu: Connect the TC and TE1 / ON.
HINT:

Indicator lights of the meter do the DTC output blinking when TC and TE1 / ON.
Depress and hold down the brake pedal.
Start the engine.
Slowly move the shift lever from P to D, then back to P.
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 teh shift lever back and forth between N and D at an inerval of 1.5 seconds for 6 seconds or more.
NOTICE:

Do not pause for more than 1.5 seconds.
Check that the D shift indicator comes on for 2 seconds.
HINT:
- When the 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 terminal TC is first turned on and perform the procedure again.
Move the shift lever from N to P.
Release the brake pedal.
Push the active test menu: TC and TE1 / OFF
NOTICE:

Be sure to turn terminals TC and TE1 off. If the terminals are on, the fluid level cannot be precisely adjusted due to fluctuations in idle speed.

HINT:
- Turning terminals TC and TE1 off activates the engine idle speed control mode.
- In the engine idle speed control mode, engine idle speed control starts when the fluid temperature becoems 35°C (95°F) or more and the engine speed is maintained at approximately 800 RPM.
- Even after terminals TC and TE1 are turned off, the fluid temperature detection mode is active until the iginiton switch is turned off.

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

Temperatures

Below Normal Operating Temperature	Normal Operating Temperature	Above Normal Operating 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)

NOTICE:

If the fluid temperature is within the normal operating 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.

ADJUST TRANSAXLE FLUID LEVEL
CAUTION:

To work while engine is idling and the radiator fan is rotating, it takes care enough.
1. Lift the vehicle.
2. Adjust fluid level

  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 hole is hot.
  2. Check the amount of fluid that comes out of the overflow plug hole.
    NOTICE:
    
    If only a small amount of fluid (approximately 1 cc) comes out of the overflow hole, then only fluid remaining in the overflow 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 hole is large, wait until the fluid flow slows and only drips come out.
  4. If no fluid comes out of the overflow hole, remove the refill plug and gasket. Then add transaxle fluid through the refill hole until fluid comes out of the overflow hole. Wait until the fluid flow slows and only drips come out.
    NOTICE:
    
    Use Toyota Genuine ATF WS.
  5. Check that the fluid flow has slowed and only drips come out.
    HINT:
    
    The fluid flow will not completely stop because the fluid expands as its temperature increases.
3. Install the overflow plug with a new gasket.
  Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf)
4. Install the refill plug with a new gasket.
  Torque: 49 N*m (408 kgf*cm, 36 ft.*lbf)
5. Lower the vehicle.
6. Turn the ignition switch OFF.
  HINT:
  
  Turning the ignition switch off exits the fluid temperature detection mode.
7. Remove the Techstream form DLC3 (when using the Techstream).
AFTER FILLING TRANSMISSION
1. Lift the vehicle.
2. Clean each part.
3. Check the fluid leak.
4. Install the fender apron seal LH, engine under cover RH, and LH.
5. Lower the vehicle.
