3-2COMPONENT PARTS

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.

1. Precaution

G3M0283
2. DIFFERENTIAL GEAR OIL LEVEL
1) Ensure the vehicle is in safe condition.
NOTE:
Do not check the oil level nor add oil to the case with the
front end of the vehicle jacked-up; this will result in an
incorrect reading of the oil level.
2) Check whether the oil level is between the upper (F)
and lower (L) marks. If it is below the lower limit mark, add
oil until the level reaches the upper mark.
G3M0854
3. OIL LEAKAGE
It is difficult to accurately determine the precise position of
a oil leak, since the surrounding area also becomes wet
with oil. The places where oil seals and gaskets are used
are as follows:
Jointing portion of the case
Transmission case and oil pump housing jointing portion
Torque converter clutch case and oil pump housing joint-
ing portion
Transmission case and transmission cover jointing por-
tion (FWD)
Transmission case and extension case jointing portion
