AUTOMATIC TRANSAXLE SYSTEM PRECAUTION NOTICE:

Perform the RESET MEMORY (AT initialization) when replacing the automatic transaxle assembly, engine assembly or ECM (See page AX-14).
Perform the REGISTRATION (VIN registration) when replacing the ECM (See page ES-13).

HINT:
The RESET MEMORY cannot be completed by only disconnecting the battery cable.

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 transaxle is composed of high precision parts which need careful inspection before reassembly. Even a small nick could cause fluid leakage or affect the performance. The instructions here are organized so that you work on only one component group at a time. This will help avoid confusion caused by 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. As far as 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 that group immediately. If a component group cannot be assembled because some parts are on order, 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.
When changing the automatic transmission fluid, use only “Toyota Genuine ATF WS” (ATF JWS3324 or NWS9638).
All disassembled parts should be washed clean and any fluid passages and holes should be blown through with compressed air.
Dry all parts with compressed air. Never use a shop rag or a piece of cloth to dry them.
Only recommended ATF or kerosene should be used for cleaning.
After cleaning, the parts should be arranged in the correct order for efficient inspection, repair, and reassembly.
When disassembling a valve body, be sure to match each valve with the corresponding spring.• New brake and clutch discs that are to 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 gaskets and rubber O-rings should be replaced with new ones.
Do not apply adhesive cements to gaskets or similar parts.
Make sure that the ends of snap rings are not aligned with any cutouts and are installed in the grooves correctly.
When replacing a worn bushing, the sub-assembly containing the bushing must also be replaced.
Check thrust bearings and races for wear and damage. Replace them as necessary.
When working with FIPG material, you must observe the following:
– Using a razor blade and a gasket scraper, remove all the old packing (FIPG) material from the gasket surface.
– 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.
