2. Automatic Transmission

Symptom and possible cause Remedy
5. Noises when cornering


1Damaged differential gear. Replace.


2Excessive wear or damage of thrust washer. Replace.


3Broken pinion mate shaft. Replace.


4Seized or damaged side bearing. Replace.
6. Gear noises
Since noises from engine, muffler, transmission, propeller shaft, wheel bearings, tires, and body are sometimes mistaken for noises
from differential assembly, be careful in checking them. Inspection methods to locate noises include coasting, accelerating, cruising,
and jacking-up all four wheels. Perform these inspections according to condition of trouble. When listening to noises, shift gears into
four wheel drive and fourth speed position, trying to pick up only differential noise.


1Improper tooth contact of hypoid gear. Readjust or replace hypoid gear set.


2Improper backlash for hypoid gear. Readjust.


3Scored or chipped teeth of hypoid gear. Replace hypoid gear set.


4Seized hypoid gear. Replace hypoid gear set.


5Improper preload for front or rear bearings. Readjust.


6Seized, scored, or chipped front or rear bearing. Replace.


7Seized, scored, or chipped side bearing. Replace.


8Vibrating differential carrier. Replace.
2. Propeller Shaft
Symptom and possible cause Remedy
1. Vibration of propeller shaft
Vibration is caused by propeller shaft during operation and is transferred to vehicle body. Generally vibration increase in proportion to
vehicle speed.


1Worn or damaged universal joint. Replace.


2Unbalanced propeller shaft due to bend or dent. Replace.


3Loose installation of propeller shaft. Retighten.


4Worn or damaged center bearing and damaged center mount-
ing rubber.Replace.
2. Tapping when starting and noise while cruising, caused by propeller shaft.


1Worn or damaged universal joint. Replace.


2Worn spline of sleeve yoke. Replace.


3Loose installation of propeller shaft. Retighten.


4Loose installation of joint. Replace.


5Worn or damaged center bearing and damaged center mount-
ing rubber.Replace.
NOTE:
Vibration while cruising may be caused by an unbalanced
tire, improper tire inflation pressure, improper wheel
alignment, etc.

B: INSTALLATION
1. SEDAN MODEL
1) Before installing backrest, ensure that trim panel, insu-
lator and seat belt are properly installed.
2) Transfer outer seat belt webbing to front of backrest and
fold backrest forward. Attach seat wire to upper hooks (2
places), and move pillow in the direction of“B”until back-
rest is aligned with lower mounting holes in body.
3) Engage backrest’s folding mechanism with striker.
4) Secure lower center and both sides of backrest to body
with bolts.
5) Slightly raise front section of cushion while pushing
down on cushion in the direction of“C”. With cushion held
in that position, attach rear section of cushion to hooks at
lower frame location.
6) Secure front of cushion to body with bolts.
CAUTION:

Before installing seat, ensure that seat belt is placed
on cushion.

Confirm that winding of three-point type seat belt

B: AUTOMATIC TRANSMISSION
1. ELECTRONIC-HYDRAULIC CONTROL SYSTEM
The electronic-hydraulic control system consists of various
sensors and switches, a transmission control module
(TCM) and the hydraulic controller including solenoid
valves. The system controls the transmission proper
including shift control, lock-up control, overrunning clutch
control, line pressure control and shift timing control. It also
controls the AWD transfer clutch. In other words, the sys-
tem detects various operating conditions from various input
signals and sends output signals to shift solenoids 1, 2 and
3 and duty solenoids A, B and C (a total of six solenoids).
