The operation of the 45RFE is very similar to the Chrysler 41TE (A604) and 42LE (A606) transaxles that you
are already familar with. The 45RFE has no internal bands, but uses several different clutch assemblies instead.
The Input Clutch Housing retains the underdrive clutch, overdrive clutch and the reverse clutch and is set up
almost identical to the 41TE transaxle, except much larger. The 45RFE also contains seperate holding clutches,
such as the 2nd clutch, 4th clutch and the low/reverse clutch. This unit also uses one overrunning or freewheel
devicecalled thelow overrunclutch.
To achieve its different gear ratios, the 45RFE applies different combinations of two clutch packs at a time, as
shown in Figure 2. In Park and Neutral, only the low/reverse clutch is applied. Notice also that a unique
characteristic of the 45RFE is its alternate 2nd gear ratio, or "2nd prime" as it is known. The 2nd prime is
enabled only during kickdown shifts above certain speeds, that enhances vehicle performance by allowing for a
higher gear ratio passing gear at highway speeds. Refer to the chart in Figure 2 for the clutches that are applied
foreach shiftlever position.
Another feature ofthisunit is thethreeplanetary gearsets,asshown inFigure2, which isonemore than youare
used to seeing in a Chrysler unit. These planetary gear sets provide a deeper 1st and reverse ratio and does not
needa seperateoverdrive unit. AllgearratiosarealsoshowninthechartinFigure2.

ELECTRICAL OPERATION
TheTransmissionControlModule(TCM)controlsallofthetransmissionfunctionsandis locatedin theengine
compartment, as shown in Figure 5. The Powertrain Control Module (PCM)does not control the transmission.
The electronic components of the 45RFE transmission consist of various sensors and switches as input
information to the TCM, that the TCM uses to determine the appropriate gear ratio and shift schedule points.
There is also the associated wiring, fuses, relays, connectors, splices and grounds for the transmission to
functionas designed. Acomplete transmissionwiringschematichasbeenprovidedforyouinFigure9.
The final output from the TCM is to the six shift solenoids and the line pressure control solenoid located in the
Solenoid Pack/Transmission Range Sensor assembly and bolted on the valve body as shown in Figure 4. The
solenoids in this transmission are unique in that some are normally vented and some are normally applied and is
illustrated in Figure 4. The TCM also communicates with other control modules, such as the PCM, currently
using the two wire CCD Bus for communication. The TCM recieves power from two sources, fused battery
power to pin 56 and fused ignition switch input to pin 11, both at the 60-way connector on the TCM. The TCM
alsohas aground tocompleteitselectricalcircuit.(SeeFigure8).
INPUTS TO THE TCM
Input and Output Shaft Speed Sensors - are located on the left side of the transmission and are illustrated in
Figure 11. The input shaft speed sensor reads input shaft speed off of a tone wheel. The TCM compares this
reading with that of the output shaft speed sensor, which is also read off of a tone wheel. This comparison
provides the TCM with gear ratio information. The crankshaft position sensor supplies the TCM with engine
RPMdata thatis alsocritical toschedulingshiftpoints.
Line Pressure Sensor - is located on the right rear of the transmission, as illustrated in Figure 11, and supplies
theTCM withline pressureinformation. Thelinepressuresensoroperatesmuchlikeathrottlepositionsensor.
Transmission Fluid Temperature Sensor - is located in the Solenoid Pack/Transmission Range Sensor and is a
thermisterthat theTCMusestomonitertransmissionfluidtemperature.
OverdriveCancel Switch- locatedon theshift leverand cancelsoverdriveoperation.
Solenoid Pack/Transmission Range Sensor- contains several different inputs to the TCM. The TRS contains
five switches that tell the TCM, through different combinations of switch states, what position the manual gear
selectorhas beenplaced. There isalsoaback-uplampswitchincorporatedintheTRS.
In addition to the switches above, there are five pressure switches to moniter pressure in the Low/Rev, Second
Clutch, Fourth Clutch, Underdrive Clutch and Overdrive Clutch hydraulic circuits. The primary function of
these switches is to help the TCM detect when clutch circuit hydraulic failures occur. The TCM continuously
monitorsthe switchesfor thecorrectstates(OpenorClosed)ineachgearasshowninthechartinFigure5.

LIMP-IN MODE OPERATION
DIAGNOSIS AND SERVICE INFORMATION
The TCM has the ability to monitor all transmission related electrical components and if it detects a problem,
takes appropriate action, and most of the time results in the TCM setting a Diagnostic Trouble Code (DTC).
Whetherthis resultsinMILillumination,orLimp-inModeoperation,dependsonthetypeofDTCthatwasset.
IftheTCMdeterminesthat transmission damage may resultfromtheDTC type that was set,theTCMwillshut
off the ground signal to the transmission control relay which will shut off all power to the transmission and the
vehiclewill bein Limp-inModeOperation.
When in Limp-in Mode Operation, with the shift lever in the "Drive" position the transmission will be in 3rd
gear,andif theshift leverismoved to"2"or "L"positionthetransmissionwill bein2nd gear. Thiswillallow the
driverto manuallyshiftthetransmissiontoLimphome.
You have been provided with the 23-way case connector pin cavity identification and pin function in Figure 7,
and 60-way TCM connector pin cavity identification and pin function in Figure 8. A complete transmission
wiringschematicisprovidedinFigure9, andtransmission controlrelaylocationinthepowerdistribution center
isshown inFigure 10.
Special tools that might be needed are illustrated in Figure 12, along with the identification of the pressure taps
that are available on the main valve body. Air pressure test passage identification is provided for you in Figure
13.
ADAPTIVE LEARNING
The 45RFE transmission uses an "Adaptive Learning" feature which allows the TCM to modify the clutch
applyratetomaintainconsistantshiftquality. Thisisdone basedon theamountofwearonthefriction elements.
The TCM then adjusts the duty cycle of the shift solenoids to achieve the smoothest possible upshifts and
downshifts. The TCM adjusts the "Clutch Volume Index" when a shift change takes place to optimize clutch to
clutch timing. Clutch Volume Index is described in Figure 6, along with proper clutch volumes and clutch
clearancesfor the45RFE transmission.

PRESSURE SWITCHES
The pressure switches are located inside the solenoid and pressure switch assembly and are only serviced by
replacingthe completeassembly.
The Transmission Control Module (TCM) is located as shown below and relies on five pressure switches to
monitor pressure in the Low/Rev, 2nd Clutch, 4th Clutch, Underdrive, and Overdrive hydraulic circuits. The
primary function of these switches is to help the TCM detect when the clutch circuit hydraulic failures occur.
The switches close at 23 psi and open at 11 psi, and indicate whether or not pressure exists. The switches are
continuously monitored by the TCM for the correct states (Open or Closed) in each gear as shown in the chart
below.

CLUTCH VOLUME INDEXES
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the volume of
fluidneeded tocompress aclutchpackproperly.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The Input Speed
Sensor sends an AC voltage signal to the TCM that represents input shaft rpm. The Output Speed Sensor
providesthe TCMwith outputshaftspeedinformation.
By comparing these two inputs, the TCM can determine actual gear ratio. This is important to the CVI
calculationbecause theTCM determinesCVIsbymonitoringhowlongittakesforagearchangetooccur.
Gear ratios can be determined by using the DRB Scan Tool and reading the Input/Output Speed Sensor values in
the "Monitors" display. Gear ratio can be obtained by dividing the Input Speed Sensor value by the Output
SpeedSensor value.
For example, if the input shaft is turning at 1000 rpm and the output shaft is turning at 500 rpm, the TCM can
determine that the gear ratio is 2:1. In 3rd gear the gear ratio changes to 1:1. The gear ratio changes as clutches
are applied and released. By monitoring the length of time it takes for a gear ratio to change following a shift
request,the TCMcan determinethevolumeoffluidusedtoapplyorreleaseafrictionelement.
The volume of transmission fluid needed to apply the friction elements are continuously updated for the
adaptivecontrols. As frictionmaterial wears,the volumeof fluidneeded toapplythefrictionelementincreases.
Certain mechanical problems within the transmission assembly such as broken return springs, out of position
snap rings, excessive clutch pack clearance, or improper assembly can cause inadequate or out-of-range CVI
readings. Also defective Input/Output Speed Sensors, wiring and poor connections may cause these same
conditions. The following chart identifies the proper CVIs, when they are monitored and updated and the
properclutch packclearances.
