2005 CHRYSLER VOYAGER Module

ment can be obtained. The result of this engagement
is a direct 1:1 mechanical link between the engine
and the transmission.
The engagement and disengagement of the TCC
are automatic and controlled by the Powertrain Con-
trol Module (PCM). The engagement cannot be acti-
vated in the lower gears because it eliminates the
torque multiplication effect of the torque converter
necessary for acceleration. Inputs that determine
clutch engagement are: coolant temperature, vehicle
speed and throttle position. The torque converter
clutch is engaged by the clutch solenoid on the valve
body. The clutch will engage at approximately 56
km/h (35 mph) with light throttle, after the shift to
third gear.
REMOVAL
(1) Remove transmission and torque converter
from vehicle. (Refer to 21 - TRANSMISSION/TRANS-
AXLE/AUTOMATIC - 41TE - REMOVAL)
(2) Place a suitable drain pan under the converter
housing end of the transmission.
CAUTION: Verify that transmission is secure on the
lifting device or work surface, the center of gravity
of the transmission will shift when the torque con-
verter is removed creating an unstable condition.
The torque converter is a heavy unit. Use caution
when separating the torque converter from the
transmission.
(3) Pull the torque converter forward until the cen-
ter hub clears the oil pump seal.
(4) Separate the torque converter from the trans-
mission.
INSTALLATION
Check converter hub and drive notches for sharp
edges, burrs, scratches, or nicks. Polish the hub and
notches with 320/400 grit paper or crocus cloth if nec-
essary. The hub must be smooth to avoid damaging
the pump seal at installation.
(1) Lubricate converter hub and oil pump seal lip
with transmission fluid.
(2) Place torque converter in position on transmis-
sion.
CAUTION: Do not damage oil pump seal or bushing
while inserting torque converter into the front of the
transmission.(3) Align torque converter to oil pump seal open-
ing.
(4) Insert torque converter hub into oil pump.
(5) While pushing torque converter inward, rotate
converter until converter is fully seated in the oil
pump gears.
(6) Check converter seating with a scale and
straightedge (Fig. 329). Surface of converter lugs
should be 1/2 in. to rear of straightedge when con-
verter is fully seated.
(7) If necessary, temporarily secure converter with
C-clamp attached to the converter housing.
(8) Install the transmission in the vehicle. (Refer
to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC
- 41TE - INSTALLATION)
(9) Fill the transmission with the recommended
fluid. (Refer to 21 - TRANSMISSION/TRANSAXLE/

TRANSMISSION CONTROL
RELAY
DESCRIPTION
The transmission control relay (Fig. 330) is located
in the Intelligent Power Module (IPM), which is
located on the left side of the engine compartment
between the battery and left fender.
OPERATION
The relay is supplied fused B+ voltage, energized by
the PCM/TCM, and is used to supply power to the sole-
noid pack when the transmission is in normal operating
mode. When the relay is ªoffº, no power is supplied to
the solenoid pack and the transmission is in ªlimp-inº
mode. After a controller reset (ignition key turned to the
ªrunº position or after cranking engine), the PCM/TCM
energizes the relay. Prior to this, the PCM/TCM verifies
that the contacts are open by checking for no voltage at
the switched battery terminals. After this is verified,
the voltage at the solenoid pack pressure switches is
checked. After the relay is energized, the PCM/TCM
monitors the terminals to verify that the voltage is
greater than 3 volts.
TRANSMISSION RANGE
SENSOR
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted
to the top of the valve body inside the transaxle andcan only be serviced by removing the valve body. The
electrical connector extends through the transaxle
case (Fig. 331).
The Transmission Range Sensor (TRS) has four
switch contacts that monitor shift lever position and
send the information to the PCM/TCM.
The TRS also has an integrated temperature sen-
sor (thermistor) that communicates transaxle tem-
perature to the TCM and PCM (Fig. 332).

MANUAL VALVE
The manual valve is operated by the mechanical
shift linkage. Its primary responsibility is to send
line pressure to the appropriate hydraulic circuits
and solenoids. The valve has three operating ranges
or positions.
CONVERTER CLUTCH SWITCH VALVE
The main responsibility of the converter clutch
switch valve is to control hydraulic pressure applied
to the front (off) side of the converter clutch piston.
Line pressure from the regulator valve is fed to the
torque converter regulator valve, where it passes
through the valve, and is slightly regulated. The
pressure is then directed to the converter clutch
switch valve and to the front side of the converter
clutch piston. This pressure pushes the piston back
and disengages the converter clutch.
CONVERTER CLUTCH CONTROL VALVE
The converter clutch control valve controls the
back (on) side of the torque converter clutch. When
the PCM/TCM energizes or modulates the LR/CC
solenoid to apply the converter clutch piston, both
the converter clutch control valve and the converter
control valve move, allowing pressure to be applied to
the back side of the clutch.
T/C REGULATOR VALVE
The torque converter regulator valve slightly regu-
lates the flow of fluid to the torque converter.
LOW/REVERSE SWITCH VALVE
The low/reverse clutch is applied from different
sources, depending on whether low (1st) gear or
reverse is selected. The low/reverse switch valve
alternates positions depending on from which direc-
tion fluid pressure is applied. By design, when the
valve is shifted by fluid pressure from one channel,
the opposing channel is blocked. The switch valve
alienates the possibility of a sticking ball check, thus
providing consistent application of the low/reverse
clutch under all operating conditions.

OPERATION
The Tire Pressure Monitoring (TPM) system uses
radio and sensor technology to monitor tire air pres-
sure levels. Sensors, mounted to each road wheel as
part of the valve stem, transmit a low frequency indi-
cating their individual pressure to a receiver located
in the Wireless Control Module (WCM) portion of the
Sentry Key Remote Electronic Entry Module
(SKREEM). These transmissions occur approximately
once every minute at speeds over 20 mph (32 km/h).
The Tire Pressure Monitoring system remains active
even if no tire pressure related message is displayed.
The sensors lay dormant (Park Mode), then wake
and start transmitting (Drive Mode) when the vehicle
first reaches speeds over 20 mph (32 km/h). Once the
wheels stop rotating for a period of approximately 30
minutes, the sensors shut down until again awaken.
Although not transmitting as when in Drive Mode,
while in Park Mode, the sensors still transmit
approximately once every 13 hours to let the receiver
know air pressure status at that time.
The receiver only receives information from the
four rotating tires. A fifth sensor may be located in
the spare tire wheel, depending on vehicle options.
Although this fifth sensor may be present, it does not
broadcast any information because it does not rotate.
When the system detects that a tire is going low,
below the Low Pressure (lamp) ON Threshold (See
following table), the driver is alerted to the situation.
The Base system illuminates an indicator lamp,
warning the driver of a pressure issue and sounds an
audible chime. In equipped with the Premium sys-
tem, the information is also displayed on the Elec-
tronic Vehicle Information Center (EVIC).
Once pressure in the suspect tire raises above the
Low Pressure (lamp) OFF Threshold, the lamp will
go out and the system returns to normal.

SENSOR - TPM
DESCRIPTION
On vehicles equipped with Tire Pressure Monitor-
ing, one tire pressure sensor is mounted to each road
wheel (Fig. 18), and depending on factory wheel
options, a sensor may be located in the spare tire
wheel. Both aluminum and steel wheels are used in
this system, although sensors for one type wheel can-
not be used in the other type wheel.Each sensor has an internal battery that lasts up
to 10 years. The battery is not serviceable. At the
time of battery failure, the sensor must be replaced.
The serviceable components of the tire pressure sen-
sor are:
²Sensor-To-Wheel Grommet
²Valve Stem Cap
²Valve Stem Core
Valve stem caps and cores are specifically designed
for the tire pressure monitoring sensors. Although
similar to standard valve stem caps and cores, they
are different.
CAUTION: Do not use a standard valve stem cap or
core in a tire pressure sensor. Always use the orig-
inal equipment style sensor cap and core.
CAUTION: Do not reuse the Sensor-To-Wheel Grom-
met. Always use a new grommet when installing a
pressure sensor and properly torque the sensor
nut.
CAUTION: Do not attempt to install a tire pressure
sensor in an aftermarket wheel. Use only in original
style factory wheels.
OPERATION
The battery operated tire pressure sensors lay dor-
mant (Park Mode), then wake and start transmitting
(Drive Mode) when the vehicle first reaches speeds
over 20 mph (32 km/h). Once the wheels stop rotat-
ing for a period of approximately 30 minutes, the
sensors shut down until again awaken. Although not
transmitting as when in Drive Mode, while in Park
Mode, the sensors still transmit approximately once
every 13 hours to let the receiver know air pressure
status at that time.
Each sensor transmits tire pressure data approxi-
mately once every minute. Each sensor's (transmit-
ter) broadcast is uniquely coded so that the wireless
control module (WCM) can monitor the state of each
of the sensors on the four rotating road wheels. The
WCM (located in the SKREEM) automatically learns
and stores the sensor's ID while driving after a sen-
sor has been replaced. There is no retraining neces-
sary.
The receiver only receives information from the
four rotating tires. A fifth sensor may be located in
the spare tire wheel, depending on vehicle options.
Although this fifth sensor may be present, it does not
broadcast any information because it does not rotate.
For additional information, refer to Appropriate
Diagnostic Information.

(a) If the heat staked or component seam loca-
tion is loose, hold the two components tightly
together and using a soldering gun with a flat tip,
melt the material securing the components
together. Do not over heat the affected area, dam-
age to the exterior of the trim panel may occur.
(b) If the heat staked material is broken or miss-
ing, use a hot glue gun to apply new material to
the area to be repaired. The panels that are being
heat staked must be held together while the apply-ing the glue. Once the new material is in place, it
may be necessary to use a soldering gun to melt
the newly applied material. Do not over heat the
affected area, damage to the exterior of the trim
panel may occur.
(4) Allow the repaired area to cool and verify the
repair.
(5) Install trim panel.
