Toyota Tacoma (2015-2018) Service Manual: Precaution
PRECAUTION
1. PRECAUTION
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.
