UNIT REPAIR (AW30–40LE) 7A4–37
Diaassembly, 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 nex t
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 DEXRON III.
General Cleaning Notes:
1. All disassembled parts should be washed clean and
any fluid passages and holes should be 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.
