Disassembly And Reassembly: Disassembly

CAUTION:
  1. 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.
  2. The working area should be covered with a rubber mat to keep it clean at all times.
  3. Do not wear any cloth gloves and do not use any rags during disassembly. Use nylon cloth if you need to use something.
  4. 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.
  5. Clutch discs, plastic thrust plates and rubber parts should be cleaned with automatic transmission fluid (ATF) so that they do not become dirty.
  6. If the transmission body has been damaged, disassemble and clean the cooler system also.
  1. Remove the torque converter. Prior to disassembly, measure input shaft end play by positioning dial indicator on input shaft.
