DODGE NEON 2000 Service Repair Manual

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 andcorrect 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.
(4) Used (original) bearing may lose up to 50 per-
cent of the original drag torque after break-in.
NOTE: All bearing adjustments must be made with
no other component interference or gear inter-
mesh, except the transfer gear bearing.
(5) Refer to the conversion chart in specifications
to convert inches to millimeter measurements. Refer
to bearing shim chart for proper shim thicknesses.

OUTPUT SHAFT BEARING
With output shaft gear removed, install a 13.65
mm (0.537 inch) and a 1.34 mm (0.053 inch) gauging
shim on the planetary rear annulus gear hub using
grease to hold the shim in place. The 13.65 mm shim
has a larger inside diameter and must be installed
over the output shaft first. The 1.34 mm shim pilots
on the output shaft.
Install output shaft gear and bearing assembly,
torque to 271 N´m (200 ft. lbs.).
To measure bearing end play:
(1) Attach Tool L-4432 to the output shaft gear.
(2) Mount a steel ball with grease into the end of
the output shaft.
(3) Push and pull the gear while rotating back and
forth to insure seating of the bearing rollers.
(4) Using a dial indicator mounted to the transaxle
case, measure output shaft end play.
(5) Once bearing end play has been determined,
refer to the output shaft bearing shim chart.
(6) The 12.65 mm (0.498 inch), 13.15 mm (0.518
inch) or 13.65 mm (0.537 inch) shims are always
installed first.These shims have lubrication slots
that are necessary for proper bearing lubrica-
tion.
(7) Shims thinner than 12.65 mm listed in the
chart are common to both the transfer shaft and out-
put shaft bearings.
(8) Use tool L-4434 to remove the retaining nut
and washer. To remove the output shaft gear use tool
L-4407.
(9) Remove the two gauging shims and install the
proper shim combination, making sure to install the
12.65, 13.15, or 13.65 mm shim first. Use grease to
hold the shims in place. Install the output shaft gear
and bearing assembly.
(10) Install the retaining nut and washer, and
torque to 271 N´m (200 ft. lbs.).
(11) Using an inch-pound torque wrench, check the
turning torque.The torque should be between 3
and 8 inch-pounds.
(12) If the turning torque is too high, install a
0.05mm (0.002 inch) thicker shim. If the turning
torque is too low, install a 0.05 mm (0.002 inch) thin-
ner shim. Repeat until the proper turning torque is 3
to 8 inch pounds.
DIFFERENTIAL BEARING
(1) Position the transaxle assembly vertically on
the support stand, differential bearing retainer side
up.
(2) Install Tool L-4436A into the differential and
onto the pinion mate shaft.
(3) Rotate the differential at least one full revolu-
tion to ensure the tapered roller bearings are fully
seated.(4) Using Tool L-4436A and an inch-pound torque
wrench, check the turning torque of the differential.

The turning torque should be between 5 and 18
inch-pounds.
(5) If the turning torque is within specifications,
remove tools. Setup is complete.
(6) If turning torque is not within specifications
proceed with the following steps.
(a) Remove differential bearing retainer from
the transaxle case.
(b) Remove the bearing cup from the differential
bearing retainer using Tool 6062A.
(c) Remove the existing shim from under the
cup.
(d) Measure the existing shim.
(e)
NOTE: If the turning torque was too high when
measured, install a.05 mm (.002 inch) thinner shim.
If the turning torque is was too low, install a.05 mm
(.002 inch) thicker shim. Repeat until 5 to 18 inch-
pounds turning torque is obtained.
Oil Baffle is not required when making shim
selection.
(f) Install the proper shim under the bearing
cup. Make sure the oil baffle is installed properly
in the bearing retainer, below the bearing shim
and cup.
(g) Install the differential bearing retainer using
Tool 5052 and C-4171. Seal the retainer to the
housing with MOPARtAdhesive Sealant and
torque bolts to 28 N´m (250 in. lbs.).
(7) Using Tool L-4436A and an inch-pound torque
wrench, recheck the turning torque of the differen-
tial.The turning torque should be between 5
and 18 inch-pounds.
TRANSFER SHAFT BEARING
(1) Use tool L-4434 to remove the retaining nut
and washer. Remove the transfer shaft gear using
tool L-4407.
(2) Install a 2.29 mm (0.090 inch) and a 1.39 mm
(0.055 inch) gauging shims on the transfer shaft
behind the governor support.
(3) Install transfer shaft gear and bearing assem-
bly and torque the nut to 271 N´m (200 ft. lbs.).
To measure bearing end play:
a. Attach tool L-4432 to the transfer gear.
b. Mount a steel ball with grease into the end of
the transfer shaft.
c. Push and pull the gear while rotating back and
forth to insure seating of the bearing rollers.
d. Using a dial indicator, measure transfer shaft
end play.
e. Refer to the Transfer Bearing Shim Chart for
the required shim combination to obtain the proper
bearing setting.
f. Use tool L-4434 to remove the retaining nut and
washer. Remove the transfer shaft gear using tool
L-4407.
