Manual Transmission Oil Inspection and Change
Inspection
1) Inspect transmission case for evidence of oil leakage.
Repair leaky point if any.
2) Make sure that vehicle is placed level for oil level check.
3) Remove level plug of transmission.
4) Check oil level.
Oil level can be checked roughly by means of level plug hole.
That is, if oil flows out of level plug hole or if oil level is found up
to hole when level plug is removed, oil is properly filled.
If oil is found insufficient, pour specified amount of specified oil.
5) Tighten level plug to specified torque.
Refer to Section 7A or 7A1 for installation and tightening torque.
Change
Change transmission oil with new specified oil referring to Section
7A or 7A1.

Automatic Transmission Fluid Inspection and Change
Inspection
1) Inspect transmission case for evidence of fluid leakage.
Repair leaky point, if any.
2) Make sure that vehicle is placed level for fluid level check.
3) Check fluid level.
For fluid level checking procedure, refer to On-vehicle service in
Section 7B1 and be sure to perform it under specified conditions.
If fluid level is low, replenish specified fluid.

replaced with a new one.
CAUTION:
Never disassemble P / S gear box. If perform this prohib-
ited service, it will affect original performance.
INSTALLATION
Reverse removal procedure for installation of steering gear box
noting the following points.
After confirming that front tire is in straight position, install steering
gear box to body temporarily. Next, with tie-rod end installed to
knuckle, set rack in position close to neutral. Then obtain the neu-
tral state by aligning match marks on pinion shaft and steering
gear case and insert steering lower joint into pinion shaft.
CAUTION:
Be sure to confirm that steering wheel and front tires
(wheels) are in straight position when inserting steering
lower joint into steering pinion shaft.
If a plug was put to disconnected pipe when removing steering
gear box, remove that plug before reconnecting pipe.
Use specified torque as given below.

race to prevent rollers in bearing race from coming out.
2) Insert the other bearing race on the opposite side into yoke, tap-
ping with a hammer until it is flush with yoke face.
3) Insert bearing races on the flange yoke side in the same way as
described in 1) and 2) above.
4) Place a metal plate on bearing races when tapping them in to
avoid damaging yoke.
5) Securely fit 4 circlips to shaft and flange yoke.
NOTE:
After assembly, check to ensure that both shaft yoke and

As the aluminum case is sealed with liquid type gas-
ket, it is necessary to use genuine sealant or its equiv-
alent on its mating surfaces when reassembling it.
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 a part of the TYPE 2 manual transmis-
sion and the transfer. The transfer is next to the trans-
mission as well, but their gear boxes are independent
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.

GENERAL DESCRIPTION
The manual transmission consists of the input shaft,
main shaft, countershaft and reverse gear which are
installed in the aluminum case. Its gears are of for-
ward five speeds in synchro mesh and reverse one
speed in constant mesh system.
The main shaft gears are held by the needle bearings
and on them the synchronizer rings and synchronizer
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.

GEAR OIL
INSPECTION AND CHANGE
1) Before changing or inspecting oil, be sure to stop engine and lift
vehicle horizontally.
2) With vehicle lifted up, check oil level and leakage. If leakage ex-
ists, correct or repair it.
3) Drain old oil and fill new specified oil as shown below by speci-
fied amount (roughly up to level hole).
NOTE:
It is highly recommended to use SAE 75W-90 gear oil.
Whenever vehicle is hoisted for any other service work
than oil change, also be sure to check for oil leakage and
status of breather hoses.
If water or rust is mixed in drained oil, be sure to check
breather hose and boot of transmission and transfer.
Gear Oil Specification
Oil grade: API GL-4
Viscosity: SAE 75W-85, 75W-90 or 80W-90
Oil Capacity:
Transmission 1.5 liters (3.2 / 2.6 US / Imp. pt)
Transfer 1.7 liters (3.6 / 3.0 US / Imp. pt)
4) Torque drain plug and level / filler plug as specified below after
applying sealant to its thread.
CAUTION:
Transmission oil must not be poured through gear shift
control lever part.
Do not loosen or remove reverse idle gear shaft bolt.

INSPECTION OF 4WD SWITCH AND BACK UP LIGHT
SWITCH
1) Undo clamp and disconnect coupler of back up light switch
and / or 4WD switch.
2) Function of back up light switch can be checked as shown in fig-
ure.
There should be conduction at these terminals only when shift
lever is shifted to reverse position.
3) Function of transfer 4WD switch can be checked in the same
manner as back up light switch.
There should be conduction at these terminals when shift lever
is shifted to 4H, and 4L positions.
Upon completion of check, connect coupler and clamp wiring har-
ness as they were.
NOTE:
When replacing switch(es), use care not to let dust enter trans-
mission through switch hole(s).
