ON-VEHICLE SERVICE
242RX00001
TRANSIMISSION FLUID LEVEL AND
CONDITION
Park vehicle on level ground and set parking brake.
With 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 80
C (176F) 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 black or smells burnt, replace it.
ATF REPLACEMENT
NOTE:
Do not overfill.
1) Remove the drain plug from oil pan and drain the
fluid.
2) Reinstall the drain plug securely.
3) With the engine OFF, add new fluid through the filler
tube.
4) Star t the engine and shift the selector into all
position from "P" through "L", and then shift into "P".
5) With the engine idling, check the fluid level. Add fluid
up to the "COLD" level on the dipstick.
6) The ATF level must be checked again for correct
level with the "HOT" level.
NOTE:
To prevent fluid leaks, the drain plug gasket must be
replaced each time this plug is removed.

DISASSEMBLY, INSPECTION AND
REASSEMBLY OF MINOR COMPONENTS
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 a
separate container while proceeding with disassembly,
inspection, repair and reassembly of other component groups.
Recommended ATF type BESCO ATF II or 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 par ts 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 thir ty 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-rings should be replaced.
3. Make sure that 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 par ts in place.

REASSEMBLY OF MAJOR COMPONENTS
Disassembly, inspection and reassembly of each
component group have been indicated in the preceding
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 for at least thir ty
minutes.
3. Apply automatic transmission fluid on the sliding or rotating
surfaces of parts before assembly.
4. Use petroleum jelly to keep small par ts in their places.
5. Do not use adhesive cements on gaskets and similar parts.
6. When assembling the transmission, be sure to use new
gaskets and O–rings.
7. Dry all par ts with compressed air - never use shop rags.
8.Be sure to install the thrust bearings and races in the
correct direction and position.
