DISASSEMBLY, INSPECTION AND

REASSEMBLY OF MINOR COMPONENTS

NOTE:

The instructions here are organized so that you work on
only one component group at a time.
This will help avoid confusion from similar-looking parts of
different subassemblies being on your workbench at the
same time.
The component groups are inspected and repaired from
the converter housing side.
As much as possible, complete the inspection, repair and
reassembly before proceeding to the next component
group. If a component group cannot be reassembled
because parts are being ordered, be sure to keep all parts
of that group in separate container while proceeding with
disassembly, inspection, repair and reassembly of other
component groups.
Recommended ATF type BESCO ATF Ⅲ.

GENERAL CLEANING NOTES:

1. All disassembled parts should be washed clean and any

fluid passages and holes blown through with compressed
air.

2. When using compressed air to dry parts, always aim

away from yourself to prevent accidentally spraying
automatic transmission fluid in your face.

3. The recommended automatic transmission fluid should be

used for cleaning.

PARTS ARRANGEMENT:

1. After cleaning, the parts should be arranged in proper

order to allow performing inspection, repairs, and
reassembly with efficiency.

2. When disassembling a valve body, be sure to keep each

valve together with the corresponding spring.

3. New brakes and clutches that are to be used for

replacement must be soaked in transmission fluid for at
least thirty minutes before assembly.

GENERAL ASSEMBLY:

1. All oil seal rings, clutch discs, clutch plates, rotating parts,

and sliding surfaces should be coated with transmission
fluid prior to reassembly.

2. All gaskets and rubber O-ring should be replaced.
3. Make sure that the ends of a snap ring are not aligned

with one of the cutouts and are installed in the groove
correctly.

4. If a worn bushing is to be replaced, the subassembly

containing that bushing must be replaced.

5. Check thrust bearings and races for wear or damage.

Replace if necessary.

6. Use petroleum jelly or vaseline to keep parts in place.
