(6) Remove the power steering cooler mounting
bolts and position the power steering cooler out of
the way.
(7) Disconnect the transmission cooler lines at the
transmission. The transmission cooler will remain on
the radiator and can be removed as an assembly.
(8) Remove the lower shroud assembly and the
electronic viscous fan wiring from the upper shroud
assembly.
(9) Remove the two radiator upper mounting bolts
(Fig. 36).
(10) Lift radiator straight up and out of engine
compartment. The bottom of the radiator is equipped
with two alignment dowels that fit into holes in the
lower radiator support panel. Rubber biscuits (insu-
lators) are installed to these dowels. Take care not to
damage cooling fins or tubes on the radiator and air
conditioning condenser when removing.
CLEANING
Clean radiator fins are necessary for good heat
transfer. The radiator and oil cooler fins should be
cleaned when an accumulation of debris has
occurred. With the engine cold, apply cold water and
compressed air to the back (engine side) of the radi-
ator to flush the radiator and/or oil coolers of debris.
INSPECTION
Inspect the radiator side tanks for cracks, broken
or missing fittings also inspect the joint where the
tanks seam up to the radiator core for signs of leak-
age and/or deteriorating seals.
Inspect radiator core for corroded, bent or missing
cooling fins. Inspect the core for bent or damaged
cooling tubes.
INSTALLATION
(1) Install rubber insulators to alignment dowels
at lower part of radiator.
(2) Lower the radiator into position while guiding
the two alignment dowels into lower radiator sup-
port. Different alignment holes are provided in the
lower radiator support for each engine application.

(10) Position heater controls tofull heatposition.
(11) Fill cooling system with coolant (Refer to 7 -
COOLING - STANDARD PROCEDURE).
(12) Operate engine until it reaches normal tem-
perature. Check cooling system and automatic trans-
mission (if equipped) fluid levels.
RADIATOR PRESSURE CAP
DESCRIPTION
All cooling systems are equipped with a pressure
cap (Fig. 37). For 5.9L engines, the pressure cap is
located on top of the radiator outlet tank. For the
3.7L/4.7L engines, the pressure cap is located on top
of the coolant degas container. The cap releases pres-
sure at some point within a range of 97-to-124 kPa
(14-to-18 psi). The pressure relief point (in pounds) is
engraved on top of the cap
The cooling system will operate at pressures
slightly above atmospheric pressure. This results in a
higher coolant boiling point allowing increased radi-
ator cooling capacity. The cap contains a spring-

DESCRIPTION
An air-to-oil transmission oil cooler is standard on
all engine packages. The transmission oil cooler is
mounted to the front of the radiator above the power
steering cooler (Fig. 2).
OPERATION
Transmission oil is routed through the cooler
where heat is removed from the transmission oil
before returning to the transmission. Vehicles
equipped with the 5.9L engine have an internal ther-
mostat that controls fluid flow through the cooler-
.When the transmission fluid is cold ( less than
operating temperature) the fluid is routed through
the cooler bypass. when the transmission fluid
reaches operating temperatures and above, the ther-
mostat closes off the bypass allowing fluid flow
through the cooler. The thermostat is serviceable.
NOTE: Vehicles with the 3.7L/4.7L engines are not
equipped with the oil cooler thermostat.
REMOVAL
(1) Disconnect the battery negative cable.
(2) Place a drain pan under the oil cooler lines.(3) Disconnect the transmission oil cooler line

engine powered models when equipped with an auto-
matic transmission.
The main water-to-oil transmission oil cooler is
mounted to a bracket on the intake side of the engine
(Fig. 4).
The air-to-oil cooler is located in front of and to the
left side of the radiator (Fig. 5).
OPERATION
The transmission oil is routed through the main
cooler first, then the auxiliary cooler where addi-
tional heat is removed from the transmission oil
before returning to the transmission. The cooler has
an internal thermostat that controls fluid flow
through the cooler. When the transmission fluid is
cold (less then operating temperature), the fluid is
routed through the cooler bypass. When the trans-
mission fluid reaches operating temperatures and
above, the thermostat closes off the bypass allowing
fluid flow through the cooler. The thermostat is ser-
vicable.

OPERATION
OPERATION - PCM
The PCM operates the fuel system. The PCM is a
pre-programmed, triple microprocessor digital com-
puter. It regulates ignition timing, air-fuel ratio,
emission control devices, charging system, certain
transmission features, speed control, air conditioning
compressor clutch engagement and idle speed. The
PCM can adapt its programming to meet changing
operating conditions.
The PCM receives input signals from various
switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations
through different system components. These compo-
nents are referred to as Powertrain Control Module
(PCM) Outputs. The sensors and switches that pro-
vide inputs to the PCM are considered Powertrain
Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon
inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant tem-
perature, throttle position, transmission gear selec-
tion (automatic transmission), vehicle speed, power
steering pump pressure, and the brake switch.
The PCM adjusts idle speed based on inputs it
receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine
coolant temperature and from inputs it receives from
the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts
ignition coil dwell. The PCM also adjusts the gener-
ator charge rate through control of the generator
field and provides speed control operation.

STANDARD PROCEDURE
STANDARD PROCEDURE - TCM QUICK LEARN
The quick learn procedure requires the use of the
DRBtscan tool.
This program allows the electronic transmission
system to recalibrate itself. This will provide the
proper transmission operation. The quick learn pro-
cedure should be performed if any of the following
procedures are performed:
²Transmission Assembly Replacement
²Transmission Control Module Replacement
²Solenoid Pack Replacement
²Clutch Plate and/or Seal Replacement
²Valve Body Replacement or Recondition
To perform the Quick Learn Procedure, the follow-
ing conditions must be met:
²The brakes must be applied
²The engine speed must be above 500 rpm
²The throttle angle (TPS) must be less than 3
degrees²The shift lever position must stay in PARK until
prompted to shift to overdrive
²The shift lever position must stay in overdrive
after the Shift to Overdrive prompt until the DRBt
indicates the procedure is complete
²The calculated oil temperature must be above
60É and below 200É
STANDARD PROCEDURE - DRIVE LEARN
When a transmission is repaired and a Quick
Learn procedure has been performed on the Trans-
mission Control Module (TCM), the following Drive
Learn procedure can be performed to fine tune any
shifts which are particularly objectionable.
NOTE: It is not necessary to perform the complete
Drive Learn procedure every time the TCM is Quick
Learned. Perform only the portions which target the
objectionable shift.
DRELECTRONIC CONTROL MODULES 8E - 21
TRANSMISSION CONTROL MODULE (Continued)

LEARN A SMOOTH 1ST NEUTRAL TO DRIVE SHIFT
Perform this procedure only if the complaint is for
a delayed or harsh shift the first time the transmis-
sion is put into gear after the vehicle is allowed to
set with the engine not running for at least 10 min-
utes. Use the following steps to have the TCM learn
the 1st N-D UD CVI.
NOTE: The transmission oil temperature must be
between 80 - 110ÉF (27 - 43ÉC).
(1) Start the engine only when the engine and
ignition have been off for at least ten (10) minutes.
(2) With the vehicle at a stop and the service
brake applied, record the 1st N-D UD CVI while per-
forming a Neutral to Drive shift. The 1st N-D UD
CVI accounts for air entrapment in the UD clutch
that may occur after the engine has been off for a
period of time.
(3) Repeat Step 1 and Step 2 until the recorded 1st
N-D UD CVI value stabilizes.
NOTE: It is important that this procedure be per-
formed when the transmission temperature is
between 80 - 110ÉF (27 - 43ÉC). If this procedure
takes too long to complete fully for the allowed
transmission oil temperature, the vehicle may be
returned to the customer with an explanation that
the shift will improve daily during normal vehicle
usage. The TCM also learns at higher oil tempera-
tures, but these values (line pressure correction
values) are not available for viewing on the DRBT
III.
LEARN A SMOOTH NEUTRAL TO DRIVE GARAGE
SHIFT
Perform this procedure if the complaint is for a
delayed or harsh shift when the transmission is put
into gear after the vehicle has had its first shift. Use
the following steps to have the TCM learn the Norm
N-D UD CVI.
NOTE: The transmission oil temperature must be
between 80 - 110ÉF (27 - 43ÉC) to learn the UD CVI.
Additional learning occurs at temperatures as low
as 0ÉF and as high as 200ÉF. This procedure may be
performed at any temperature that experiences poor
shift quality. Although the UD CVI may not change,
shift quality should improve.
(1) Start the vehicle engine and shift to drive.
(2) Move the vehicle forward to a speed of at least
16 km/h (10 MPH) and come to a stop. This ensures
no air is present in the UD hydraulic circuit.
(3) Perform repeated N-D shifts at a stop while
pausing in Neutral for at least 2-3 seconds and mon-itor Norm N-D UD CVI volume until the value stabi-
lizes. The value will change during the N-D shift.
This is normal since the UD value is different for the
N-D shift then the normal value shown which is used
for 4-3 coastdown and kickdowns. Perform repeated
shifts in this temperature range until the Norm N-D
UD CVI value stabilizes and the N-D shifts become
smooth.
LEARN THE 1ST 2-3 SHIFT AFTER A RESTART OR
SHIFT TO REVERSE
Use the following steps to have the TCM learn the
1st 2-3 shift OD CVI.
NOTE: The transmission oil temperature must be
above 80ÉF (27ÉC).
(1) With the vehicle engine running, select reverse
gear for over 2 seconds.
(2) Shift the transmission to Drive and accelerate
the vehicle from a stop at a steady 15 degree throttle
opening and perform a 2-3 shift while noting the 1st
2-3 OD CVI.
(3) Repeat Step 1 and Step 2 until the 1st 2-3
upshift becomes smooth and the 1st 2-3 OD CVI sta-
bilizes.
LEARN A SMOOTH 2-3 AND 3-4 UPSHIFT
NOTE: The transmission oil temperature must be
above 110ÉF (43ÉC).
Use the following steps to have the TCM learn the
OD and 4C CVI's.
(1) Accelerate the vehicle from a stop at a steady
15 degree throttle opening and perform multiple 1-2,
2-3, and 3-4 upshifts. The 2nd 2-3 shift following a
restart or shift to reverse will be shown during the
shift as a value between the 1st 2-3 OD CVI and the
normal OD CVI. Updates to the normal OD CVI will
occur after the 2nd shift into 3rd gear, following a
restart or shift to reverse.
(2) Repeat Step 1 until the 2-3 and 3-4 shifts
become smooth and the OD and 4C CVI become sta-
ble.
LEARN A SMOOTH 4-3 COASTDOWN AND PART
THROTTLE 4-3 KICKDOWN
NOTE: The transmission oil temperature must be
above 110ÉF (43ÉC).
Use the following steps to have the TCM learn the
UD shift volume.
(1) At a vehicle speed between 64-97 km/h (40-60
MPH), perform repeated 4-3 kickdown shifts.
