Adjustment [12/2019 - 10/2022]: Procedure
- PRECAUTIONS AND WORK DESCRIPTION
- 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.
- 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.
- The UA80E automatic transaxle assembly requires Toyota Genuine ATF WS.
- The adjustment should be performed according to the procedures and notes.

The actual automatic transaxle fluid temperature can be checked on the Data List using the GTS.
Powertrain > Transmission > Active Test
Active Test Display Activate the TC Terminal Data List Display A/T Oil Temperature No. 1 - According to the display on the GTS, perform the Data List "A/T Oil Temperature No. 1".
- According to the display on the GTS, perform the Active Test Activate the TC Terminal and set it to "ON".
- Check the automatic transaxle fluid temperature.NOTE:
- If the automatic transaxle fluid temperature is below 45°C (113°F), proceed to the next step. Recommended automatic transaxle fluid temperature: 35°C (95°F) or less.
- If the automatic transaxle fluid temperature is 45°C (113°F) or more, turn the ignition switch off and wait until the automatic transaxle fluid temperature drops below 45°C (113°F).
- Depress and hold 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 automatic transaxle fluid through each part of the automatic transaxle assembly.
