CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during automatic transaxle fluid replacement are shown below.

PROCEDURE

1. PRECAUTIONS AND WORK DESCRIPTION

(a) The UA80E automatic transaxle assembly does not have an oil filler tube and oil level gauge. When adding automatic transaxle fluid, add automatic transaxle fluid through the refill hole on the automatic transaxle case sub-assembly. The automatic transaxle fluid level can be adjusted by draining excess automatic transaxle fluid (allowing excess automatic transaxle fluid to overflow) through the overflow plug of the transaxle housing.

HINT:

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

(b) Before adjusting the automatic transaxle fluid level, add the specified amount of automatic transaxle fluid when the engine is cold and warm up the engine to circulate the automatic transaxle fluid in the automatic transaxle assembly. Ensure that the automatic transaxle fluid temperature is as specified and the engine is idling.

(c) The UA80E automatic transaxle assembly requires Toyota Genuine ATF WS.

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