( 1) - Different interval may be required for normal and severe
service. Severe service is described as long periods of engine
idling, frequent short trip operation of less than 5 miles,
trailer towing, off-highway operation, snow removal operation,
or operating in dusty or excessively hot conditions.
( 2) - Service interval is not available from manufacturer. Use filter-
minder on top of air cleaner housing to determine condition of
air filter. If filter-minder is in the Red zone, replace air
filter. Reset filter-minder by depressing button on top of
filter-minder.
( 3) - Replace coolant at 30,000 miles or 24 months whichever occurs
first. Replace coolant at 24 months regardless of mileage. After
first coolant change, replace coolant every 24 months or 30,000
miles thereafter.
( 4) - Monthly interval is not available from manufacturer.
( 5) - Does not require routine adjustments.

NOTE: For models not covered in this article, see STARTERS -
AVENGER, SEBRING COUPE & TALON article.
DESCRIPTION
Bosch, Melco and Mitsubishi starters use a planetary gear
train that transmits power from starter motor to pinion shaft. Six
permanent magnets (Bosch and Melco starters) or 4 permanent magnets
(Mitsubishi starters) are used, eliminating potential field wire-to-
frame short circuits.
Nippondenso starter is a 4-field, 4-brush, 12-volt motor with
a solenoid mounted within the housing. The unit has a 2-to-1 reduction
gear set in a die cast aluminum housing. Starter has serviceable gear
and clutch assembly only. If starter solenoid fails, entire starter
motor must be replaced.
All models use a starter relay in starter circuit between the
battery and starter solenoid terminal. Automatic Transmission (A/T)
equipped vehicles use a Park/Neutral Position (PNP) switch or a
Transmission Range (TR) sensor to provide ground path for the starter
relay. Manual Transmission (M/T) equipped vehicles use a clutch pedal
position switch to provide battery voltage from ignition switch to the
starter relay. See WIRING DIAGRAMS.

TROUBLE SHOOTING
NOTE: See TROUBLE SHOOTING article in GENERAL INFORMATION.

Fig. 10: Manual Transmission & Clutch

PCM controls operation of electric cooling fan. PCM operates fan
through radiator fan relay by grounding or ungrounding relay control
circuit. PCM regulates engine idle speed through IAC motor when fan is
on.
SHIFT INDICATOR LIGHT
PCM provides ground for shift indicator light on models
equipped with manual transmission. Based on engine speed, throttle
position, and vehicle speed, PCM turns shift indicator light on to
advise driver to shift to a higher gear for optimum fuel economy.
SPEED CONTROL SERVO
System is electrically actuated and vacuum operated. Controls
are located on steering wheel. Controls consist of 3 buttons: OFF/ON,
RESUME/ACCEL and SET/DECEL. Speed control servo is controlled by PCM.
System will operate at 35-85 MPH.
TACHOMETER
PCM provides signal to drive tachometer.
TORQUE CONVERTER CLUTCH (TCC) SOLENOID
PCM controls torque converter lock-up through TCC solenoid.
PCM controls lock-up according to various operating conditions.
TRANSMISSION GOVERNOR SOLENOID
PCM controls solenoid to regulate line pressure for shift
control.
TRANSMISSION OVERDRIVE/OVERRIDE (OD/OR) SWITCH INDICATOR
LIGHT
PCM controls indicator light on OD/OR switch on models
equipped with overdrive automatic transmission.
TRANSMISSION OVERDRIVE (OD) SOLENOID
On models equipped with OD transmission, PCM controls 3-4 OD
upshift and downshift through OD solenoid. PCM determines optimum OD
shift scheduling for all operating conditions.

WARNING: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
MANUAL TRANSMISSION
NOTE: For manual transmission replacement procedures, see
appropriate article in CLUTCHES.
AUTOMATIC TRANSMISSION
DAKOTA & DURANGO
Removal
1) Disconnect negative battery cable. Raise and support
vehicle. Disconnect and remove necessary skid plates and exhaust
components for transmission removal. Remove engine-to-transmission
struts (if equipped). These struts are located between front of
transmission and engine.
2) Ensure area around transmission oil cooler lines fitting
are clean. Disengage retainer on quick-disconnect cooler line fitting.
Pull cooler line from transmission oil cooler.
CAUTION: Crankshaft position sensor must be removed from transmission
housing before removing transmission to prevent damage to
crankshaft position sensor.
3) Remove starter. Disconnect electrical connector for
crankshaft position sensor. On 2.5L, crankshaft position sensor is
mounted on driver's side of transmission housing. See Fig. 1. On 3.9L,
5.2L and 5.9L, crankshaft position sensor is mounted on passenger's
side of transmission housing. See Fig. 2.
4) Remove crankshaft position sensor bolts or nuts. Remove
crankshaft position sensor from transmission housing. Remove dipstick,
dipstick tube and "O" ring from transmission.
5) Remove torque converter cover. Place reference mark on
flexplate and torque converter for installation reference. Rotate
crankshaft clockwise and remove torque converter bolts.
6) Place reference mark on drive shaft flanges for
installation reference. Remove drive shaft from transmission. On 4WD
models, disconnect drive shaft from transfer case. Disconnect shift
rod for transfer case from transfer case shift lever.
7) On all models, disconnect necessary control cables, wiring
harnesses, and shift linkage or cable from transmission. Support rear
of engine with jack stand. Using transmission jack, slightly raise
transmission to release pressure from rear mount and rear crossmember.
8) Remove bolts securing rear support and rear mount to
transmission and rear crossmember. Raise transmission slightly. Slide
exhaust hanger arm from bracket on rear support. Remove rear support
and rear mount.
9) Remove rear crossmember located below the transmission. On
4WD models, disconnect electrical connectors from transfer case. On

(1) - Approximate quantity listed.

plug is located on rear of transfer case, just below identification
tag.
3) Fill transfer case with appropriate type of transfer case
fluid until fluid level is even with bottom of fill plug hole on
transfer case. See RECOMMENDED FLUID. Install and tighten transfer
case fill plug to specification. See TORQUE SPECIFICATIONS.
Power Take-Off (PTO) Adapter (Ram Pickup 2WD 2500 & 3500)
1) Ensure vehicle is parked on level surface. Remove drain
plug from rear of PTO adapter. See Fig. 3. Allow fluid to drain from
PTO adapter.
2) Reinstall drain plug. Tighten drain plug to specification.
