Automatic Trans: Overhaul: Transaxle: Disassembly

CAUTION: Because the automatic transaxle is manufactured from high-precision parts, sufficient care must be taken not to scratch or damage these parts during disassembly and reassembly.

CAUTION: The working area should be covered with a rubber mat to keep it clean at all times.

CAUTION: Do not wear any cloth gloves and do not use any rags during disassembly. Use nylon cloth if you need to use something.

CAUTION: 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.

CAUTION: Clutch discs, plastic thrust plates and rubber parts should be cleaned with automatic transmission fluid (ATF) so that they do not become dirty.

CAUTION: If the transmission body has been damaged, disassemble and clean the cooler system also.
