Unit Disassembly

TRANSAXLE UNIT COMPONENTS














DISASSEMBLY
General Notice
1. Disassemble transaxle in a clean area (dust proof work space) to prevent entry of dust into mechanisms.
2. Inspect individual transaxle components in accordance with Quick Diagnosis Chart during disassembly.
3. Use only plastic hammers when applying force to separate light alloy case joints.
4. Never use shop towels during disassembly; they may leave particles that can clog fluid passages.
5. Several parts resemble one another; organize them so that they do not get mixed up.
6. Disassemble control valve assembly and thoroughly clean it when a clutch or brake band has burned or when ATF has degenerated.

Cleaning Notice
1. Clean transaxle exterior thoroughly with a steam cleaner or cleaning solvents before disassembly.
2. Clean removed parts with cleaning solvent, and dry with compressed air. Clean out all holes and passages with compressed air, and check that there are no obstructions.

Caution: Wear eye protection when using compressed air to clean components.

NOTICE: Do not allow ATF to spill when removing torque converter
