clock setting DODGE NEON 1999 Service Repair Manual

When the ignition switch is in the OFF position, or
when the radio frequency is being displayed, time
keeping is accurately maintained.
The procedure for setting the clock varies slightly
with each radio. The correct procedure is described in
the individual radio operating instructions. Refer to
the Owner's Manual supplied with the vehicle.
INSTRUMENT CLUSTER
There are two conventional instrument cluster
assemblies available. The clusters electronically drive
the speedometer, odometer, and gauges (Fig. 1) and
(Fig. 2).
GAUGES
All gauges in the electronic clusters are the analog
type gauges. When the ignition switch is moved to
the OFF position, the cluster drives each gauge to its
lowest position.
WARNING AND INDICATOR LAMPS
The instrument cluster has warning lamps and
indicators for the following systems:
²Airbag
²Anti-lock Brakes (ABS) if equipped
²Brake warning
²Charging System
²Door Ajar
²High beam indicator
²Low oil pressure
²Malfunction indicator (service engine soon) lamp
²Right and left turn signals.
²Seat belt warning
DIAGNOSIS AND TESTING
AIRBAG WARNING SYSTEM
For testing of this system refer to Group 8M,
Restraint Systems.
BRAKE SYSTEM WARNING LAMP TEST
The brake warning lamp illuminates when the
parking brake is applied with ignition switch turned
to the ON position. The same lamp will also illumi-
nate if one of the two service brake systems fail the
when brake pedal is applied.
To test the system:
²As the ignition switch is turned to the start posi-
tion the lamp should light.
²Turn ignition switch to the ON position and
apply the parking brake. The lamp should light.

GENERAL INFORMATION
INTRODUCTION
Operating instructions for the factory installed
audio systems can be found in the Owner's Manual
provided with the vehicle.
The vehicles are equipped with an Interior (Igni-
tion Off Draw) fuse in the Power Distribution Center
located in the engine compartment. After the Interior
(IOD) fuse or battery has been disconnected the clock
will require resetting.
DESCRIPTION AND OPERATION
INTERFERENCE ELIMINATION
The radio utilizes a ground wire plugged on to a
blade terminal and is bolted to the radio chassis.
Both connector and terminal should be securely
attached. The engine has three separate ground
straps to suppress ignition noise which may interfere
with radio reception.
²Left engine mount clip on strap
²Engine to shock tower reinforcement
²Rear strut to body, clip-on strap
Inductive type spark plug cables in the high ten-
sion circuit of the ignition system complete the inter-
ference suppression. Faulty or deteriorated spark
plug wires should be replaced.
In addition, there is a capacitor mounted on the
cylinder head which also helps suppress ignition
noise.
DIAGNOSIS AND TESTING
AUDIO DIAGNOSTIC TEST PROCEDURES
CAUTION: The CD player will only operate between
approximate temperatures of -23ÉC and +65ÉC (-10ÉF
and +145ÉF).
Whenever a radio malfunction occurs;
(1) First check FUSES:
(a) Power Distribution Center (PDC), Interior
lamp fuse, M1 - Radio Memory Feed
(b) Fuse Block:
(I) Fuse 12, Illumination in the fuse block
(II) Fuse 16, Ignition feed in the fuse block
NOTE: The vehicles are shipped with the INTERIOR
LAMP fuse disconnected.
(2) Verify, the radio wire harness are properly con-
nected before starting normal diagnosis and repair
procedures. Refer to Audio Diagnosis table and/or
Group 8W, Wiring Diagrams, Radio Section.
PLAUDIO SYSTEM 8F - 1

(3) Move selector lever on transaxle two detents
forward from full rearward position. This is selector
D position.
(4) Read pressures on both gauges as throttle lever
on transaxle is moved from full clockwise to the full
counterclockwise position.
(5) Line pressure should read 52 to 58 psi with
throttle lever clockwise. Pressure should gradually
increase to 80 to 88 psi. as lever is moved counter-
clockwise.
(6) Kickdown release is pressurized only in direct
drive and should be same as line pressure within 3
psi, up to kickdown point.
(7) This tests pump output, pressure regulation,
and condition of rear clutch, front clutch, and
hydraulic circuits.
TEST FOUR (SELECTOR IN REVERSE)
(1) Attach 300 psi gauge to low-reverse port.
(2) Operate engine at 1600 rpm for test.
(3) Move selector lever on transaxle four detents
forward from full rearward position. This is selector
R position.
(4) Low/reverse pressure should read 180 to 220
psi with throttle lever clockwise. Pressure should
gradually increase to 260 to 300 psi. as lever is
moved counterclockwise.
(5) This tests pump output, pressure regulation,
and condition of front clutch and rear servo hydraulic
circuits.
(6) Move selector lever on transaxle to D position
to check that low/reverse pressure drops to zero.
(7) This tests for leakage into rear servo, due to
case porosity, which can cause reverse band burn out.
TEST RESULT INDICATIONS
(1) If proper line pressure, minimum to maximum,
is found in any one test, the pump and pressure reg-
ulator are working properly.
(2) Low pressure in D, 1, and 2 but correct pres-
sure in R, indicates rear clutch circuit leakage.
(3) Low pressure in D and R, but correct pressure
in 1 indicates front clutch circuit leakage.
(4) Low pressure in R and 1, but correct pressure
in 2 indicates rear servo circuit leakage.
(5) Low line pressure in all positions indicates a
defective pump, a clogged filter, or a stuck pressure
regulator valve.
GOVERNOR PRESSURE
Test only if transaxle shifts at wrong vehicle
speeds when throttle cable is correctly adjusted.
(1) Connect a 0-150 psi pressure gauge to governor
pressure take-off point. It is located at lower right
side of case, below differential cover.
(2) Operate transaxle in third gear to read pres-
sures. The governor pressure should respondsmoothly to changes in mph and should return to 0
to 3 psi when vehicle is stopped. High pressure
(above 3 psi) at standstill will prevent the transaxle
from downshifting.
THROTTLE PRESSURE
No gauge port is provided for throttle pressure.
Incorrect throttle pressure should be suspected if
part throttle upshift speeds are either delayed or
occur too early in relation to vehicle speed. Engine
runaway on shifts can also be an indicator of low
throttle pressure setting, or misadjusted throttle
cable.
In no case should throttle pressure be adjusted
until the transaxle throttle cable adjustment has
been verified to be correct.
CLUTCH AND SERVO AIR PRESSURE TESTS
A no±drive condition might exist even with correct
fluid pressure, because of inoperative clutches or
bands. The inoperative units, clutches, bands, and
servos can be located through a series of tests. This
is done by substituting air pressure for fluid pressure
(Fig. 5).
The front and rear clutches, kickdown servo, and
low/reverse servo can be tested by applying air pres-
sure to their respective passages. To make air pres-
sure tests, proceed as follows:
NOTE: Compressed air supply must be free of all
dirt and moisture. Use a pressure of 30 psi.
Remove oil pan and valve body. Refer to Valve
Body for removal procedure.
FRONT CLUTCH
Apply air pressure to front clutch apply passage
and listen for a dull thud, which indicates that front
clutch is operating. Hold air pressure on for a few
seconds and inspect system for excessive oil leaks.
REAR CLUTCH
Apply air pressure to rear clutch apply passage
and listen for a dull thud, which indicates that rear
clutch is operating. Also, inspect for excessive oil
leaks. If a dull thud cannot be heard in the clutches,
place finger tips on clutch housing and again apply
air pressure. Movement of piston can be felt as the
clutch is applied.
KICKDOWN SERVO (FRONT)
Direct air pressure into KICKDOWN SERVO ON
passage. Operation of servo is indicated by a tighten-
ing of front band. Spring tension on servo piston
should release the band.

quality, and part throttle downshift sensitivity. If the
setting is too long, early shifts and slippage between
shifts may occur. If the setting is too short, shiftsmay be delayed and part throttle downshifts may be
very sensitive.
(1) Perform transaxle throttle pressure cable
adjustment while engine is at normal operating tem-
perature.
(2) Release cross-lock on the cable assembly (pull
cross-lock upward) See (Fig. 14).
(3) To insure proper adjustment, the cable must be
free to slide all the way toward the engine, against
its stop, after the cross-lock is released.
(4) Move transaxle throttle control lever fully
clockwise, against its internal stop, and press cross-
lock downward into locked position.
The adjustment is complete and transaxle throttle
cable backlash was automatically removed.
Test cable freedom of operation by moving the
transaxle throttle lever forward (counterclockwise).
Then slowly release it to confirm it will return fully
rearward (clockwise).
No lubrication is required for any component of the
throttle cable system.

(6) Verify the shift lever and transaxle are in the
PARK position. Rotate collar on the shift cable
adjuster end up until it seats against the plastic
housing. NOTE: If the collar will not rotate to the
fully detented lock position, rotate the collar back to
its initial unlocked position. Position the ATX in the
gated PARK position. Apply a slight load to the shift
lever, fore or aft in vehicle, while simultaneously
rotating the collar upward to the LOCK position. The
collar must seat against the plastic housing to
achieve the required detented lock position. The gear-
shift linkage should now be properly adjusted.
Check adjustment as follows:
(7) Detent position for NEUTRAL and DRIVE
should be within limits of hand lever gate stops.
(8) Key start must occur only when the shift lever
is in PARK or NEUTRAL positions.
THROTTLE PRESSURE CABLE ADJUSTMENT
PROCEDURE
The throttle pressure cable adjustment is very
important to proper transaxle operation. This adjust-
ment positions a valve which controls shift speed,
shift quality, and part throttle downshift sensitivity.
If the setting is too long, early shifts and slippage
between shifts may occur. If the setting is too short,
shifts may be delayed and part throttle downshifts
may be very sensitive.(1) Perform transaxle throttle pressure cable
adjustment while engine is at normal operating tem-
perature.
(2) Release cross-lock on the cable assembly (pull
cross-lock upward) see (Fig. 197).
(3) To ensure proper adjustment, the cable must be
free to slide all the way toward the engine, against
its stop, after the cross-lock is released.
(4) Move transaxle throttle control lever fully
clockwise, against its internal stop, and press cross-
lock downward into locked position.
The adjustment is complete and transaxle throttle
cable backlash was automatically removed.
Test cable freedom of operation by moving the
transaxle throttle lever forward (counterclockwise).
Then slowly release it to confirm it will return fully
rearward (clockwise).
No lubrication is required for any component of the
throttle cable system.
SHIFTER/IGNITION INTERLOCK SYSTEM
If ignition switch cannot be turned to the LOCK
position, with shifter in PARK, an adjustment of the
Interlock System may be required. To adjust Shifter/

with needle±nose pliers and pull back on cable. This
will allow the ignition switch to be turned to the
LOCK or ACCESSORY position.
(8) Check that the interlock cable slug is com-
pletely seated into the shifter interlock lever.
(9) Check that the ignition switch is still in the
LOCK or ACCESSORY position.
(10) Pry up the adjuster lock on the shifter/igni-
tion interlock cable (Fig. 198).
(11) The spring on the interlock cable should auto-
matically compensate for the slack in the adjuster.
(12) Then snap down the interlock adjuster lock
onto cable.
(13) After adjusting the interlock system, perform
the interlock system operation check. See Interlock
System Operation Check in this section.
BAND ADJUSTMENT
KICKDOWN BAND (FRONT)
The kickdown band adjusting screw is located on
left side (top front) of the transaxle case.
(1) Loosen locknut and back±off nut approximately
five turns. Test adjusting screw for free turning in
the transaxle case.
(2) Using wrench, tighten adjusting screw to 8
N´m (72 in. lbs.).
(3) Back±off adjusting screw the number of turns
listed in Specifications. Hold adjusting screw in this
position and tighten locknut to 47 N´m (35ft. lbs.)
LOW/REVERSE BAND (REAR)
To adjust low/reverse band, proceed as follows:
(1) Loosen and back off locknut approximately five
turns.
(2) Using an inch-pound torque wrench, tighten
adjusting screw to 5 N´m (41 in. lbs.) true torque.(3) Back±off adjusting screw the number of turns
listed under Specifications. A chart is located at the
rear of this section.
(4) Tighten locknut to 14 N´m (10 ft. lbs.).
HYDRAULIC CONTROL PRESSURE ADJUSTMENTS
LINE PRESSURE
An incorrect throttle pressure setting will cause
incorrect line pressure readings even though line
pressure adjustment is correct. Always inspect and
correct throttle pressure adjustment before adjusting
the line pressure.
The approximate adjustment for line pressure is
1-5/16 inches, measured from valve body to inner
edge of adjusting nut. However, due to manufactur-
ing tolerances, the adjustment can be varied to
obtain specified line pressure.
The adjusting screw may be turned with an Allen
wrench. One complete turn of adjusting screw
changes closed throttle line pressure approximately
1-2/3 psi. Turning adjusting screw counterclockwise
increases pressure, and clockwise decreases pressure.
THROTTLE PRESSURE
Throttle pressures cannot be tested accurately;
therefore, the adjustment should be measured if a
malfunction is evident.
(1) Insert gauge pin of Tool C-3763 between the
throttle lever cam and kickdown valve.
(2) By pushing in on tool, compress kickdown
valve against its spring so throttle valve is com-
pletely bottomed inside the valve body.
(3) While compressing spring, turn throttle lever
stop screw with adapter C-4553. Turn until head of
screw touches throttle lever tang, with throttle lever
cam touching tool and throttle valve bottomed. Be
sure adjustment is made with spring fully com-
pressed and valve bottomed in the valve body.
BEARING ADJUSTMENT PROCEDURES
(1) Take extreme care when removing and install-
ing bearing cups and cones.Use only an arbor
press for installation, as a hammer may not
properly align the bearing cup or cone.Burrs or
nicks on the bearing seat will give a false end play
reading, while gauging for proper shims. Improperly
seated bearing cup and cones are subject to low-mile-
age failure.
(2) Bearing cups and cones should be replaced if
they show signs of pitting or heat distress.
(3) If distress is seen on either the cup or bearing
rollers, both cup and cone must be replaced.
NOTE: Bearing end play and drag torque specifica-
tions must be maintained to avoid premature bear-
ing failures.
