GENERAL DESCRIPTION
This automatic transmission is a full automatic type with 3-speed plus overdrive (O / D).
The torque converter is a 3-element, 1-step and 2-phase type and is equipped with an electronically controlled
lock-up mechanism. The gear shift device consists of 3 sets of planetary gear units, 3 disc type clutches, 4 disc
type brakes and 3 one-way clutches. The gear shift is done by selecting one of 6 positions (ªPº, ªRº, ªNº, ªDº, ª2º
and ªLº) by means of the select lever installed on the floor. On the shift knob, there is an overdrive (O / D) cut switch
which allows shift-up to the overdrive mode (except at 4L) and shift-down from the overdrive mode. Also, by using
the P / N change switch located on the console box, it is possible to select the gear change timing of 2 modes, nor-
mal and power.

LEVEL CHECK AT ROOM TEMPERATURE
The fluid level check at room temperature performed after repair or
fluid change before test driving is just preparation for level check of
normal operating temperature. The checking procedure itself is the
same as that described previously. If the fluid level is between FULL
COLD and LOW COLD, proceed to test drive. And when the fluid
temperature has reached the normal operating temperature, check
fluid level again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) With engine is cool, remove drain plug from oil pan and drain A / T
fluid.
3) Install drain plug.

shaft.
4) Likewise, take out front propeller shaft. (if equipped)
5) Remove nut from the end of select cable and bracket to set
cable free.
6) Remove select cable bracket by removing its 2 bolts.
7) Remove exhaust No.1 and No.2 pipe.
8) Remove transmission stiffener (right side) if equipped.
9) Unclamp and disconnect oil cooler hoses from pipes.
NOTE:
To avoid leakage of transmission fluid, plug open ends of
oil cooler pipes and hoses right after they are discon-
nected.
10) Remove torque converter housing lower plate.
11) Holding drive plate stationary with special tool or the like, re-
move torque converter mounting bolts with wrench.

7C1-2 CLUTCH
The clutch is a diaphragm-spring clutch of a dry single
disc type. The diaphragm spring is of a tapering-finger
type, which is a solid ring in the outer diameter part,
with a series of tapered fingers pointing inward.
The disc, carrying torsional coil springs, is positioned
on the transmission input shaft with an involute spline
fit.
The clutch cover is secured to the flywheel, and car-
ries the diaphragm spring in such a way that the pe-
ripheral edge part of the spring pushes on the pres-
sure plate against the flywheel (with the disc in be-
tween), when the clutch release bearing is held back.
This is the engaged condition of the clutch.Depressing the clutch pedal causes the release bear-
ing to advance and pushes on the tips of the tapered
fingers of the diaphragm spring. When this happens,
the diaphragm spring pulls the pressure plate away
from the flywheel, thereby interrupting the flow of
drive from flywheel through clutch disc to transmis-
sion input shaft.

7D
TRANSFER 7D-1
The aluminum transfer case directly connected to the
back of the transmission contains the input gear,
countershaft & gear, output rear shaft, output low gear
and output front shaft (for front drive) connected by
way of the hyvo-chain.
The transfer has such a selective mechanism as to
enable the shift control lever to make selection of high
speed (direct connection with transmission output:
main shaft), low speed (speed reduction by input
gear, counter gear and output low gear) or neutral by
way of the reduction sleeve located between input
gear and output low gear, and selection of two-wheel-
drive (high speed only) or four-wheel-drive (high or
low speed) by way of the front drive clutch sleeve lo-cated at the center of the output rear shaft. Also, with
a synchronizer installed to the front drive clutch, it is
possible to change the drive mode between 2WD
(high speed only) and 4WD (high speed only) even
while running.
The front drive shift fork has an auxiliary spring to
make a smooth shift from 4H to 2H possible.
The case has an oil gutter and a plate at synchronizer
to provide proper lubrication even under the strict
conditions of use.
WARNING:
For towing the vehicle for the purpose of repair or
the like, follow the towing instructions in OWN-
ER'S MANUAL.

DIAGNOSIS
DIAGNOSIS TABLE
Before attempting to repair the transfer or related components for any reason other than mechanical failure, the
condition and probable causes should be identified.
Transfer failures are revealed by shifting difficulties such as excessive shifting effort, gear clash, or gear grinding.
When any of these conditions occur, the following inspections should be made before disassembling the transfer.
1) Check transfer oil level for insufficient or incorrect oil. Refer to ªTransfer and Differential Oil Inspection and
Changeº in SECTION 0B ªMAINTENANCE AND LUBRICATIONº.
2) Check transfer mountings for wear or looseness.
3) Check gearshift control lever for distortion or excessive wear.
After performing the above inspections, refer to following diagnosis table.
