7A3-18 ON-VEHICLE SERVICE (AW30–40LE)
Transmission Fluid Level and Condition
Inspection
Park vehicle on level ground and set parking brake.
W ith the engine idling, move the shift lever through all
positions from “P" to “L", then return to position “P".
Check to see if the level of fluid comes to “HOT" range
of about 75 °
°°
°
C (167 °
°°
°
F) on the dipstick gauge.
If the level of fluid is too low, replenish to bring it to
maximum level in “HOT" range.
Inspection of fluid condition. If the ATF is except
normality (refer to the following table) or smells burnt,
try to find these cause and replace it.

Major Components
Disassembly, inspection and reassembly of each
component group is indicated in the following chapter.
Before reassembly, make sure, again, that all
component groups are assembled correctly.
If something wrong is found in a certain component
group during assembly, inspect and repair this group
immediately.
General Assembly Notes:
1. The automatic transmission is composed of highly
precision-finished parts, necessitating careful
inspection before assembly because even a small
nick could cause fluid leakage or affect
performance.


2. Before assembling new clutch discs and brake
bands, soak them in automatic transmission fluid fo
r
at least thirty minutes.
3. Apply automatic transmission fluid on the sliding o
r
rotating surfaces of parts before assembly.
4. Use petroleum jelly to keep small parts in thei
r
palces.
5. Do not use adhesive cements on gaskets and similar parts.
6. W hen assembling the transmission, be sure to use new gaskets and O-rings.
7. Dry all parts with compressed air - never use shop rags.
8. Be sure to install the thrust bearings and races in the correct direction and position.

7A4–36 UNIT REPAIR (AW30–40LE)
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 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 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 inproper 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.
