• If automatic transaxle parts are replaced, perform the following as necessary referring to the table below:
  • Registration of the transaxle compensation code (See page ).
  
  
  • Initialization of the transaxle compensation code (See page ).
  
  
  • Road test (See page ).

    Table

    Replaced Part		Transaxle Compensation Code	Road Test	Reset Memory (Learned Values)
    Automatic Transaxle Assembly		Input	Necessary	Reset
    Valve Body Assembly		Initialize	Necessary	Reset
    Shift Solenoid Valve SL1 and/or SL2		-	Necessary	-
    Shift Solenoid Valve SL3 and/or SL4		Initialize	Necessary	Reset
    TCM (If possible, read the transaxle compensation code from the previous TCM)	Possible	Input (Into the new TCM)	Necessary	Reset
    	Impossible	Initialize	Necessary	Reset

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

NOTICE:

• The automatic transaxle 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 rubber O-rings must be replaced.
• Do not apply adhesive cement to gaskets 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 FIPG material, the following must be observed:
  • Using a razor blade and a gasket scraper, remove all the old packing (FIPG) 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 packing (FIPG) material must be removed and reapplied.
