2. PRECAUTION

NOTICE:

  • When disconnecting the cable from the negative (-) battery terminal, initialize the following systems after the cable is reconnected (See page Perform the Reset Memory procedures (A/T initialization) after replacing ).
  • Perform the Reset Memory procedures (A/T initialization) after replacing the automatic transmission assembly, transmission valve body assembly or any of the shift solenoid valves (See page HINT: ).

    HINT:

    Reset Memory cannot be completed by only reconnecting the cable to the negative (-) battery terminal.

  • Perform Registration (VIN registration) when replacing the ECM (See page ).

CAUTION:

When using compressed air, always aim away from yourself to prevent Automatic Transmission Fluid (ATF) or kerosene from spraying on your face.

NOTICE:

  • The automatic transmission is composed of precision-made parts, necessitating careful inspection before reassembly because even a small nick could cause fluid leakage or affect performance.
  • The procedures are organized so that you work on only one component group at a time. This will help avoid confusion with similar-looking parts of different sub-assemblies being on your workbench at the same time.
  • The component groups are inspected and repaired from the converter housing side.
  • Whenever possible, complete the inspection, repair and reassembly before proceeding to the next component group. If a defect is found in a certain component group during reassembly, inspect and repair this group immediately. If a component group cannot be assembled because parts are being ordered, be sure to keep all parts of the group in a separate container while proceeding with disassembly, inspection, repair and reassembly of other component groups.
  • Use of Toyota Genuine ATF WS is recommended.
  • All disassembled parts should be washed clean, and compressed air should be blown through any fluid passages and holes.
  • Dry all parts with compressed air. Never use cloth.
  • The recommended ATF or kerosene should be used for cleaning.
  • After cleaning, the parts should be arranged in the order they were removed for efficient inspection, repairs and reassembly.
  • New discs for the brakes and clutches that will be used for replacement must be soaked in ATF for at least 15 minutes before reassembly.
  • All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with ATF prior to reassembly.
  • All old gaskets and rubber O-rings must be replaced.
  • Do not apply adhesive cement to gaskets and similar parts.
  • Make sure that the ends of the snap rings are not aligned with any cutouts. Also make sure that snap rings are correctly installed into the grooves.
  • If a worn bushing is to be replaced, the sub-assembly containing the bushing must also be replaced.
  • Check the thrust bearings and races for wear or damage. Replace them if necessary.
  • Use petroleum jelly to keep parts in place.
  • When working with seal packing material, the following must be observed:
    • Using a razor blade and a gasket scraper, remove all the old seal packing material from the gasket surface.
    • Thoroughly clean all components to remove any loose material.
    • Clean both sealing surfaces with a non-residue solvent.
    • Parts must be reassembled within 10 minutes of application. Otherwise, the seal packing material must be removed and reapplied.
