1. Precaution
When disassembling or assembling the automatic
transmission, observe the following instructions.
1) Workshop
Provide a place that is clean and free from dust. Principally
the conventional workshop is suitable except for a dusty
place. In a workshop where grinding work, etc. which pro-
duces fine particles is done, make independent place
divided by the vinyl curtain or the equivalent.
2) Work table
The size of 1 x 1.5 m (40 x 60 in) is large enough to work,
and it is more desirable that its surface be covered with flat
plate like iron plate which is not rusted too much.
3) Cleaning of exterior
(1) Clean the exterior surface of transmission with
steam and/or kerosene prior to disassembly, however it
should be noted that vinyl tape be placed on the air
breather or oil level gauge to prevent infiltration of the
steam into the transmission and also the cleaning job
be done away from the place of disassembly and
assembly.
(2) Partial cleaning will do, depending on the extent of
disassembly (such as when disassembly is limited to
some certain parts).
4) Disassembly, assembly and cleaning
(1) Disassemble and assemble the transmission while
inspecting the parts in accordance with the Diagnostics.
(2) During job, don’t use gloves. Don’t clean the parts
with rags: Use chamois or nylon cloth.
(3) Pay special attention to the air to be used for clean-
ing. Get the moisture and the dust rid of the air as much
as possible. Be careful not to scratch or dent any part
while checking for proper operation with an air gun.
(4) Complete the job from cleaning to completion of
assembly as continuously and speedily as possible in
order to avoid occurrence of secondary troubles
caused by dust. When stopping the job unavoidably
cover the parts with clean chamois or nylon cloth to
keep them away from any dust.
(5) Use kerosene, white gasoline or the equivalent as
washing fluid. Use always new fluid for cleaning the
automatic transmission parts and never reuse. The
used fluid is usable in disassemble and assemble work
of engine and manual transmission.
(6) Although the cleaning should be done by dipping
into the washing fluid or blowing of the pressurized
washing fluid, the dipping is more desirable. (Do not rub
with a brush.) Assemble the parts immediately after the
cleaning without exposure to the air for a while. Besides
in case of washing rubber parts, perform the job quickly
not to dip them into the washing fluid for long time.

3-2SERVICE PROCEDURE
1. Precaution

G3M0854
(7) Apply the automatic transmission fluid (ATF) onto
the parts immediately prior to assembly, and the speci-
fied tightening torque should be observed carefully.
(8) Use vaseline if it is necessary to hold parts in the
position when assembling.
(9) Drain ATF and differential gear oil into a saucer so
that the conditions of fluid and oil can be inspected.
(10) Do not support axle drive shaft, stator shaft, input
shaft or various pipes when moving transmission from
one place to another.
(11) Always discard old oil seals and O-ring, and install
new ones.
(12) Do not reuse old aluminum (overrunning clutch
pipes, etc.) pipes, gaskets, spring pins. Install new
ones.
(13) Be sure to replace parts which are damaged,
worn, scratched, discolored, etc.

A: INSPECTION
1. ATF LEVEL
1) Raise ATF temperature to 60 to 80°C (140 to 176°F)
from 40 to 60°C (104 to 140°F) (when cold) by driving a
distance of 5 to 10 km (3 to 6 miles).
NOTE:
The level of ATF varies with fluid temperature. Pay atten-
tion to the fluid temperature when checking oil level.
2) Make sure the vehicle is level. After selecting all posi-
tions (P, R, N, D, 3, 2, 1), set the selector leveler in“P”
range. Measure fluid level with the engine idling.
NOTE:
After running, idle the engine for one or two minutes before
measurement.
3) If the fluid level is below the center between upper and
lower marks, add the recommended ATF until the fluid level
is found within the specified range (above the center
between upper and lower marks). When the transmission
is hot, the level should be above the center of upper and
lower marks, and when it is cold, the level should be found
below the center of these two marks.
CAUTION:
Use care not to exceed the upper limit level.
ATF level varies with temperature. Remember that
the addition of fluid to the upper limit mark when the
transmission is cold will result in the overfilling of
fluid.
4) Fluid temperature rising speed
By idling the engine
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 25 minutes

Time for temperature rise to 30°C (86°F) with atmo-
spheric temperature of 0°C (32°F): Approx. 8 minutes
By running the vehicle
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 10 minutes
5) Method for checking fluid level upon delivery or at peri-
odic inspection
Check fluid level after a warm-up run of approx. 10 min-
utes. During the warm-up period, the automatic transmis-
sion functions can also be checked.

A: DISASSEMBLY
1. EXTERNAL PARTS
1) Place the transmission unit on a work bench, with the
oil pan facing down.
CAUTION:
Be careful not to bend or damage external parts.

2) Remove the drain plug, and drain differential oil. Tighten
the plug temporarily after draining.
G3M0326
3) Remove the drain plug, and drain automatic transmis-
sion fluid (ATF). Tighten the plug temporarily after draining.

4) Extract the torque converter clutch assembly.
NOTE:
Extract the torque converter clutch horizontally. Be care-
ful not to scratch the bushing inside the oil pump shaft.
Note that oil pump shaft also comes out.
