Disassembly And Assembly: 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.
