TRANSMISSION CONTROL
RELAY
DESCRIPTION
The transmission control relay (Fig. 336) 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 TCM, and is used to supply power to the solenoid
pack when the transmission is in normal operating mode.
When the relay is ªoffº, no power is supplied to the sole-
noid 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 TCM energizes the
relay. Prior to this, the TCM verifies that the contacts
are open by checking for no voltage at the switched bat-
tery terminals. After this is verified, the voltage at the
solenoid pack pressure switches is checked. After the
relay is energized, the 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. 337) .
The Transmission Range Sensor (TRS) has four
switch contacts that monitor shift lever position and
send the information to the TCM.
The TRS also has an integrated temperature sen-
sor (thermistor) that communicates transaxle tem-
perature to the TCM and PCM (Fig. 338) .

TRANSAXLE IDENTIFICATION
NOTE: Since transaxles use unique gear ratios for
each of the two engine applications, it is imperative
that the transaxle is properly identified, and the cor-
rect transaxle assembly number is used when
ordering service parts.The transaxle model, assembly part number, build
date, and final drive ratio (FDR) can be found on a
metal tag fastened to the transaxle case on the bell-
housing (Fig. 2). A barcode label is also glued to the
transaxle bellhousing, and it too includes the trans-
axle part number.

SHIFT FORK AND SHAFT
DESCRIPTION
The T850 utilizes a unique shift fork and shaft
arrangement consisting of three shift forks and two
shafts as shown in (Fig. 276). This system is oper-
ated by the shift cover assembly, which combined
with a unique gearshift cable design, offers a higher
mechanical advantage over traditional shift systems.
This arrangement results in less friction and lower
shift cable loads for smoother, more positive opera-
tion. The shift fork assemblies are constructed of
brass, float about the shafts with the aid of needle
bearings, and are serviced only as fork/bearing
assemblies.
SYNCHRONIZER
DESCRIPTION
The T850 transaxle uses two styles of synchronizer
assemblies; a conventional single-cone style is used
for the 5th/Reverse and 3rd/4th applications (Fig.
277), and a dual-cone style for the 1st/2nd gear appli-
cation (Fig. 278).
DISASSEMBLY
Place synchronizer in a clean shop towel and wrap.
Press on inner hub. Carefully open up shop towel
and remove springs, balls, keys, hub, and sleeve.
CLEANING
CLEAN
Do not attempt to clean the blocking rings in sol-
vent. The friction material will become contaminated.
Place synchronizer components in a suitable holder
and clean with solvent. Air dry.
INSPECTION
INSPECT
Proper inspection of components involve:
²Teeth, for wear, scuffed, nicked, burred, or bro-
ken teeth

SENSOR - TPM
DESCRIPTION
On vehicles equipped with Tire Pressure Monitor-
ing, one tire pressure sensor is mounted to each
wheel (Fig. 19). Each sensor has an internal battery
that lasts up to 10 years. The battery is not service-
able. At the time of battery failure, the sensor must
be replaced. The serviceable components of the tire
pressure sensor 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 try to install a tire pressure sen-
sor in a steel wheel or aftermarket wheel. Use only
in original style factory wheels.
OPERATION
Tire pressure sensors are battery operated. They
transmit tire pressure data once every minute at
speeds above 20 mph (32 km/h) or up to once every
hour when stationary (parked). For additional infor-
mation, refer to Appropriate Diagnostic Information.
CAUTION
CAUTION: The use of tire sealants is strictly prohib-
ited for vehicles equipped with the Tire Pressure
Monitoring system. Tire sealants can clog tire pres-
sure sensors.
CAUTION: Tire pressure sensor valve stem caps
and cores are specially designed for the sensors.
Due to risk of corrosion, do not use a standard
valve stem cap or core in a tire pressure sensor in
place of the original equipment style sensor cap
and core.CAUTION: Do not attempt to install a tire pressure
sensor in a steel wheel or aftermarket wheel. Use
tire pressure sensors in original style factory
wheels only.
NOTE: TPM thresholds have been established for
the original tire size equipped on the vehicle. Use
original size tires only to maintain system accuracy.
DIAGNOSIS AND TESTING - TIRE PRESSURE
SENSOR
NOTE: Tire pressure may increase from 2 to 6 psi
(14 to 41 kPa) during normal driving conditions. Do
NOT reduce this normal pressure build up.
If a fault in the system is detected, always check
air pressure in the tires first with a known accurate
air gauge and correct the inflation pressure. If any
tire is low, inspectalltires.
If gauge-read pressure in the tires does not reflect
the reading on the EVIC, retrain the sensors, then
reevaluate (Refer to 22 - TIRES/WHEELS/TIRE
PRESSURE MONITORING/SENSOR - STANDARD
PROCEDURE). Refer to the appropriate diagnostic
information for complete diagnosis of the Tire Pres-
sure Monitoring System.
STANDARD PROCEDURE - TIRE PRESSURE
SENSOR RETRAIN
WARNING: DEATH OR SERIOUS INJURY CAN
OCCUR IF MAGNETICALLY SENSITIVE DEVICES
ARE EXPOSED TO THE RELEARN MAGNET. MAG-
NETS CAN AFFECT PACEMAKERS.
CAUTION: Never attempt to train more than one
vehicle at a time. System is capable of reading tire
pressure sensor transmissions from other near-by
vehicles.
Each time a wheel rotation or tire pressure sensor
replacement occurs the tire pressure sensors must be
retrained. This is necessary to inform the Electronic
Vehicle Information Center (EVIC) that a sensor
change was made and where. Retraining is accom-
plished through the EVIC used in conjunction with a
Re-learn Magnet, Special Tool 8821.
22 - 10 TIRES/WHEELSRS
ProCarManuals.com

All aluminum wheels have wheel mounting (lug)
nuts with an enlarged nose. This enlarged nose is
necessary to ensure proper retention of the wheels.
DIAGNOSIS AND TESTING - WHEEL
INSPECTION
Inspect wheels for:
²Excessive runout
²Dents, cracks or irregular bends
²Damaged wheel stud (lug) holes
²Air Leaks
NOTE: Do not attempt to repair a wheel by hammer-
ing, heating or welding.
If a wheel is damaged, an original equipment
replacement wheel should be used. When obtaining
replacement wheels, they must be equivalent in load
carrying capacity. The diameter, width, offset, pilot
hole and bolt circle of the wheel should be the same
as the original wheel.
WARNING: FAILURE TO USE EQUIVALENT
REPLACEMENT WHEELS MAY ADVERSELY
AFFECT THE SAFETY AND HANDLING OF THE
VEHICLE.
WARNING: REPLACEMENT WITH USED WHEELS IS
NOT RECOMMENDED. THE SERVICE HISTORY OF
THE WHEEL MAY HAVE INCLUDED SEVERE TREAT-
MENT OR VERY HIGH MILEAGE. THE RIM COULD
FAIL WITHOUT WARNING.
CLEANING - ALUMINUM WHEEL CARE
Chrome plated and painted aluminum wheels
should be cleaned regularly using mild soap and
water to maintain their luster and to prevent corro-
sion.
Care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent
damage to the wheels. Any of the ªDO NOT USEº
items listed below WILL damage chrome plated and
painted aluminum wheels.
DO NOT USE:
²any abrasive metal cleaner
²any abrasive cleaning pad or brush
²any cleaner that contains an acid (this will
immediately react with and discolor the chromium
surface)
²chrome polish (unless it is buffed off immedi-
ately after application)
²oven cleaner
²a car wash that uses carbide-tipped wheel clean-
ing brushes
