GENERAL INFORMATION
Following are general descriptions of major compo-
nents used in XJ (Cherokee)/YJ (Wrangler) audio sys-
tems. Refer to Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
RADIOS
Radio options for the XJ and YJ models include an
AM/FM stereo or an AM/FM stereo/cassette receiver.
Both units are Electronically-Tuned Radios (ETR)
and include a clock function. For more information
on radio features, setting procedures, and control
functions refer to the owner's manual.
IN-LINE FUSE
Each radio receives fused battery feed when the ig-
nition switch is in the ON or ACCESSORY position.
There is an additional in-line fuse in the back of the
radio chassis. The in-line fuse (Fig. 1) will blow to
protect the vehicle electrical system in the event of
internal radio failure.
IGNITION-OFF DRAW FUSE
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various ac-
cessories that require current when the ignition
switch is in the OFF position, including the clock and
radio station preset memory functions. The fuse is re-
moved to prevent battery discharge during vehicle
storage.The IOD fuse should be checked if the radio station
preset memory or clock functions are erratic or inop-
erative. The IOD fuse is located in the Power Distri-
bution Center (PDC). Refer to underside of PDC
cover for IOD fuse identification.
RADIO ILLUMINATION RELAY
All radios are connected to a radio illumination re-
lay. The relay controls the source of battery feed for
radio/clock display illumination.
When the park and headlamp switch is in the OFF
position, the radio illumination relay remains de-en-
ergized. The radio/clock display receives full battery
voltage through the normally closed contacts of the
relay. This results in the radio/clock display being il-
luminated at full brightness for easier visibility in
daylight.
When the park and headlamp switch is in the ON
position, the radio illumination relay coil is ener-
gized. With the relay coil energized, the normally
closed contacts of the relay open, and the normally
open contacts of the relay close. This causes the ra-
dio/clock display to receive battery feed through the
instrument panel dimmer switch. The display illumi-
nation brightness can now be adjusted with other
panel lamps for night visibility.
SPEAKERS
Speaker system options include two, four or six (XJ
only) speaker locations. On XJ model two-speaker
systems, one speaker is located in each front door.
Four-speaker systems add one speaker at each end of
a rear-mounted overhead sound bar. The premium
six-speaker option upgrades all the speakers in the
above locations, and adds one tweeter at each end of
the lower instrument panel.
On YJ model two-speaker systems, one speaker is
located at each end of the instrument panel. Four-
speaker systems add one speaker at each end of a
rear-mounted overhead sound bar.

justment must be performed properly and in the cor-
rect sequence. The correct sequence is line pressure
adjustment first and throttle pressure adjustment
last.
Line Pressure Adjustment
Measure distance from the valve body to the inner
edge of the adjusting screw with an accurate steel
scale (Fig. 124).
Distance should be 33.4 mm (1-5/16 in.).
If adjustment is required, turn the adjusting screw
in, or out, to obtain required distance setting.
The 33.4 mm (1-5/16 in.) setting is an approxi-
mate setting. Because of manufacturing toler-
ances, it may be necessary to vary from this
dimension to obtain desired pressure.
One complete turn of the adjusting screw changes
line pressure approximately 1-2/3 psi (9 kPa). Turn-
ing the adjusting screw counterclockwise increases
pressure while turning the screw clockwise decreases
pressure.
Throttle Pressure Adjustment
Insert Gauge Tool C-3763 between the throttle le-
ver cam and the kickdown valve stem (Fig. 125).
Push the gauge tool inward to compress the kick-
down valve against the spring and bottom the throt-
tle valve.
Maintain pressure against kickdown valve spring.
Turn throttle lever stop screw until the screw head
touches throttle lever tang and the throttle lever cam
touches gauge tool.
The kickdown valve spring must be fully com-
pressed and the kickdown valve completely
bottomed to obtain correct adjustment.
TRANSMISSION ASSEMBLY TIPS
Do not allow dirt, grease, or foreign material to en-
ter the case or transmission components during as-
sembly. Keep the transmission case and componentsclean. Also make sure the tools and workbench area
used for assembly are equally clean.
Shop towels used for wiping off your hands and
service tools must be made oflint freematerials.
Lint will adhere to transmission parts and could in-
terfere with valve operation, or even restrict fluid
passages.
Lubricate the transmission components with Mopar
ATF Plus during reassembly. Use Mopar Door-Ease,
or Ru-Glyde on seals and O-rings to ease installation.
Petroleum jelly can also be used to hold thrust
washers and plates in position during assembly oper-
ations. However,do notuse chassis grease, bearing
grease, white grease, or similar lubricants on any
transmission part. These types of lubricants can
eventually block or restrict fluid passages and valve
operation. Use petroleum jelly only.
Do not force parts into place. Most of the transmis-
sion components are easily installed by hand when
properly aligned. If a part seems extremely difficult
to install, it is either misaligned or incorrectly assem-
bled. Also verify that thrust washers, thrust plates
and seal rings are correctly positioned before assem-
bly. These parts can interfere with proper assembly if
mispositioned or ``left out'' by accident.
TRANSMISSION ASSEMBLY AND ADJUSTMENT
PROCEDURES
SERVO INSTALLATION
(1) Install rear servo piston, spring and spring re-
tainer. Compress rear servo spring and retainer with
Compressor Tool C-3422-B or a large C-clamp.
(2) Install front servo piston, spring and rod guide.
Compress front servo rod guide with Valve Spring
Compressor C-3422-B and install servo snap ring.
