Repair Procedures: Removal

CAUTION:

When the solenoid valve Diagnostic Trouble Codes (DTC) is on, perform the following procedure to replace it.
Automatic transaxle is composed of delicate components. Be careful not to cause any damage on the component in the course of assembly and disassembly.
Maintain clean condition so that foreign substance does not get into the automatic transaxle.
Use a coated apron, latex gloves, and stainless tray to prevent foreign substance from getting into the transaxle.
Automatic transaxle fluid (ATF) can be reused. Collect it using a clean 10-liter beaker.

Shut off the high voltage circuit. (Refer to HIGH VOLTAGE SHUT-OFF PROCEDURES
Remove the under cover. (Refer to Engine Mechanical System - "ENGINE ROOM UNDER COVER ")
Drain the engine coolant. (Refer to Engine Mechanical System - "COOLANT ")
Drain the coolant of hybrid motor cooling system. (Hybrid Motor System - "COOLANT ")
