REQUIRED SERVICE MATERIALS7A1-5 . . . . . .
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.

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 2.6 liters (5.5 / 4.6 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 thread of plug (c).
CAUTION:
Transmission oil must not be poured through gear shift
control lever part.
