0A-8 GENERAL INFORMATION
When removing the battery, be sure to disconnect the nega-
tive cable first and then the positive cable. When reconnect-
ing the battery, connect the positive cable first and then the
negative cable, and replace the terminal cover.
When removing parts that are to be reused, be sure to keep
them arranged in an orderly manner so that they may be rein-
stalled in the proper order and position.
Whenever you use oil seals, gaskets, packing, O-rings, lock-
ing washers, split pins, self-locking nuts, and certain other
parts as specified, be sure to use new ones. Also, before
installing new gaskets, packing, etc., be sure to remove any
residual material from the mating surfaces.
Make sure that all parts used in reassembly are perfectly
clean.
When use of a certain type of lubricant, bond or sealant is
specified, be sure to use the specified type.
ªAº: Sealant 99000-31150
Be sure to use special tools when instructed.

COMPRESSION SYSTEM DIAGNOSIS
Compressor troubles are mainly following three types: gas leakage, noise and insufficient pressure.
Compressor gas leakages in most cases develop from the shaft seal. When detecting gas leakage, always use
a leak tester. If a small amount of oil seeps out from the shaft seal, there is no necessity of replacing the seal. The
shaft seal has been designed to allow a small amount of oil to leak out for lubricating purpose. Thus, the shaft seal
should be replaced only when a large amount of compressor oil is leaking out or when gas leakage is discovered
by using gas tester.
In regard to noise and insufficient pressure, repairs should be made only after diagnosing the trouble properly.

2) Check each connection for fluid leakage and bleed air.
Refer to ªAIR BLEEDING PROCEDUREº in this section.
3) With engine idling, turn steering wheel and warm up engine till
temperature of fluid in P/S fluid reservoir rises to 50 ± 60C (122
± 140F).
4) Check back pressure by measuring hydraulic pressure with en-
gine idling and hands off steering wheel.
Back pressure: Lower than 1000 kPa (10 kg / cm
2, 142 psi)
When back pressure is higher than specified values, check con-
trol valve and piping for clogging.

plate. Then take off bleeder plug cap from brake pipe and con-
nect pipe (or pipes) to wheel cylinder just enough to prevent fluid
from leaking.

Be sure to check gasket for deterioration or any damage be-
fore installation and replace if found defective.
2) Tighten wheel cylinder to brake back plate to specified torque.
3) Torque flare nut (or nuts) of brake pipe which was connected in

The manual transmission consists of the input shaft,
main shaft, counter shaft and reverse gear which are
installed in the aluminum and castings cases. Its
gears are of forward five speeds in synchro mesh and
reverse one speed in sliding idler gear arrangement
system.
The main shaft gears are held by the needle bear-
ings and on them the synchronizer rings and syn-
chronizer sleeve & hubs are assembled.
The gear shift lever case is located at the upper be-
hind the transmission case and has a cam which pre-
vents direct gear shift from the 5th speed gear to the
reverse gear.As the aluminum and castings cases are sealed with
liquid type gasket, it is necessary to use genuine seal-
ant or its equivalent on its mating surfaces when reas-
sembling them. Also, the case fastening bolts must be
tightened to specified torque by means of the torque
wrench and tightening over or below the specified
torque should be avoided.
The description under ON-VEHICLE SERVICE in this
section covers the transfer partially which is next to
the transmission as well, but their gear boxes are in-
dependent and each of them has its own drain and
level / filler plugs for the oil change or the level check.
For the repair procedure of the transfer unit, refer to
Section 7D.

OPERATION CHECK
Whenever shift solenoid valves and TCC (lock-up) solenoid valve
are removed from transmission, verify their valve function physical-
ly before they are reinstalled.
1) Apply oiler to solenoid valve and give compression by hands
and then check to be sure that transmission fluid from oiler does
not come out of holes in solenoid valve when battery voltage is
not conducted.
2) Under the same conditions as above, conduct battery voltage
and then make sure that fluid comes out with vigor.
NOTE:
If fluid does not come out with vigor in above step 2 in-
spection, do not re-use that solenoid valve.
Figure at the left shows shift solenoid valve check.
Check TCC solenoid valve also in the same way.
