AUTOMATIC TRANSMISSION:

• When fasteners are removed, always reinstall them at the same location from which they were removed. If a fastener needs to be replaced, use the correct part number fastener for that application.
• If the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may be used. Fasteners that are not reused, and those requiring thread locking compound will be called out.
• The correct torque value must be used when installing fasteners that require it. If the above conditions are not followed, parts or system damage could result.
