Toyota Venza: Adjustment

ADJUSTMENT

PROCEDURE

1. PRECAUTIONS AND WORK DESCRIPTION

(a) 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 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.

(b) 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.


(c) The U660E automatic transaxle requires Toyota Genuine ATF WS.

(d) The adjustment should be performed according to the procedures and notes.

2. WORK FLOW

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


3. BEFORE FILLING TRANSAXLE WITH FLUID

(a) Lift the vehicle.

NOTICE:

Set the vehicle on a lift so that the vehicle is kept level when it is lifted up.

(b) Remove the No. 2 engine under cover and front fender apron LH.

4. PERFORM INITIAL FILLING

NOTICE:

If the transaxle is hot (ATF 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])

(a) 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 Add Specified Amount of Fluid procedure.

Operations that do not require initial filling

  • Disconnection of the oil cooler tube or oil cooler hose
  • Repair of fluid leak due to a loose case plug, or a faulty plug gasket or O-ring
  • Installation of a new transaxle with torque converter (filled fluid parts)

(b) 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 No. 1 transmission oil filler tube, temporarily tighten the overflow plug.

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

7. ADJUST FLUID LEVEL

CAUTION:

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

(a) Lift the vehicle.

NOTICE:

Set the vehicle on a lift so that the vehicle is kept level when it is lifted up.

(b) Adjust the 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 plug 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 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.

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.


(c) Install the overflow plug with a new gasket.

Torque:

40 N·m {408 kgf·cm, 30 ft·lbf}


(d) Install the refill plug with a new gasket.

Torque:

49 N·m {500 kgf·cm, 36 ft·lbf}


(e) Lower the vehicle.

(f) Turn the ignition switch off.
