INSTALLATION
To install, follow the removal steps in the reverse order, noting
the following points;
Adjustment of select lever and control rod
1) Place the vehicle on a level surface.
NOTE:
If the vehicle is not on a level surface, the shift select cable
set position will vary with the movement of the engine. To
prevent possible misadjustment of the cable, the vehicle
must be placed on a level surface.
2) Install the shift control rod (1) to the transfmission select
lever (2), and then place the lever in the "N" position.
3) Set select lever in the "N" position.
4) Push select lever forward and secure it (using a rubber
band (3), etc.) so that pin comes into contact with the wall
of detent plate.
5) Install the shift control rod (1) to the selector lever arm (4).
NOTE:
Do not apply to threaded portions.
6) After adjustment, operate select lever on a trial basis to
makes sure of its smooth operation and no abnormal
indication in each position.
Adjustment of shift lock cable
1) Set ignition key in "LOCK" position and selector lever in "P"
position.
2) Adjust cable screw cap on selector lever side to provide a
gap (slack for cable) of 1–2mm between rod on steering
lock side and stopper.
Adjust cap as follows:
a. Pull screw cap (1) in arrow direction to put off slack of
inner cable.
b. With cable kept as (a), adjust gap between nut (2) and
bracket to 5mm (0.2in).
c. Lock inner cable by tur ning nut (3) while holding nut (2) in
place.
NOTE:
Clean the rod threads and do not apply oil to the threaded
portions.Nꞏm(kgꞏm / lbꞏft)

alternately, star ting with clutch disc, onto the rear planetary
gear assembly.
11. Oil seal ring
Coat the oil seal ring with ATF and install it to the output
shaft.
NOTE:
Do not spread the ring ends too much.
12. Output shaft
Install output shaft into rear planetary assembly.

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.
