Disassembly And Assembly: Disassembly

CAUTION:

• Because the automatic transaxle is manufactured from high-precision parts, care must be taken not to scratch or damage these parts during disassembly and assembly.
• Work on a rubber mat and keep it clean at all times.
• Do not wear any cloth gloves and do not use any shop towels during disassembly. Use only nylon cloth, paper towels or any other lint-free material.
• Parts which have been disassembled should all be cleaned. Metal parts can be cleaned with normal detergent, but they should be dried completely using compressed air.
• Clutch discs, plastic thrust plates and rubber parts should be cleaned with automatic transmission fluid (ATF).
• If the transaxle body has been damaged, disassemble and clean the cooler system.
