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.

REMOVAL
1) Remove 4 screws at the front and rear and 2 clips at the center
then take off front and rear center console boxes.
NOTE:
To remove clip, push in its center pin first.
2) Remove console box bracket by removing bolts and lift up boot
cover and boot No. 2.
3) Remove boot clamp and then remove boot No. 1 from transmis-
sion shift lever case.
4) With gear shift control case cover pushed down with fingers, turn
it to counter clockwise and take out shift control lever.
5) Take out transfer shift control lever in similar manner as de-
scribed above.
INSPECTION AND INSTALLATION
1) Check shift control lever lower portion and control lever locating
sheet for excessive wear, and boot for damage. Correct or re-
place if necessary.
2) Apply grease to pivot portions and seat, then install shift control
lever.
ªAº: Grease 99000-25010
3) Perform above steps also for transfer shift control lever.
4) If control lever locating bolts (a) are replaced or retightened,
torque them as specified below.
Replacing of control lever locating bolts requires thread lock ce-
ment.
