Disassembly

DISASSEMBLY

CAUTION:
^ Because the automatic transmission is manufactured from high-precision parts, sufficient care must be taken not to scratch or damage these parts during disassembly and reassembly.
^ During the work, always use bare hands or vinyl gloves. Do not use cotton gloves. Use nylon cloth or paper towels when necessary. Do not use shop towels.
^ Parts which have been disassembled should be cleaned. Metal parts can be cleaned with normal detergent, but they should be dried completely using compressed air.
^ Clutch discs, plastic thrust race and rubber parts should be cleaned with ATF automatic transmission fluid so that they do not become dirty.
^ If the transmission body has been damaged, disassemble and clean the cooler system also.
