Adjustment [12/2012 - 10/2015]: Procedure

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

PRECAUTIONS AND WORK DESCRIPTION

The U760E automatic 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.
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 U760E automatic transaxle requires Toyota Genuine ATF WS.

Perform the adjustment according to the following procedures and notes.

ADJUST FLUID LEVEL

WARNING:

Use caution while the engine 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.

Adjust the fluid level.

Using a 6 mm hexagon socket wrench, remove the overflow plug and gasket.

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 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.

*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.

*2:

If no fluid comes out of the overflow plug hole, remove the refill plug and gasket. Then add transaxle fluid into 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 ATF WS.

Check that the fluid flow has slowed and only drops come out.

HINT:

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

Install a new gasket and the overflow plug.

Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf)

Install a new gasket and the refill plug.

Torque: 49 N*m (500 kgf*cm, 36 ft.*lbf)
