P2703- INADEQUATE ELEMENT VOLUME UD
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Whenever the engine is running. The UD clutch volume index (CVI) is updatedduring a 4-3 kickdown with
throttle angle between 10 and 54 degrees. Transmission temperature must be at least 43° C (110° F).
Set Condition:
When the UD CVI falls below 11.
Possible Causes
BROKEN UD ACCUMULATOR SPRING(S)
BROKEN UD CLUTCH PISTON SPRING OR DISLODGED SNAP RING
INTERNAL LEAKAGE IN PUMP OR VALVE BODY ASSEMBLIES

Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The volumes of the transmission fluid needed to apply the friction elements are continuously monitored and learned
for adaptive controls. As the clutch friction material wears, the volume of fluid needed to apply the clutch increases.
Certain transmission mechanical problems can cause near-zero learned volumes resulting in setting a DTC. The
DTC will usually set with other DTC’s, which indicates an internal transmission problem.

When Monitored:
Initially at power-up, then every 10 seconds thereafter. The solenoid circuits will also be tested immediately
after a gear ratio or pressure switch error is detected.
Set Condition:
After three consecutive solenoid continuity test failures, or one failure if test is run in response to a gear ratio
or pressure switch error.Note: This DTC is strictly an electrical fault and does not apply to any internal
transmission failures.
Possible Causes
RELATED TCM POWER INPUT DTCS PRESENT
(T118) MS SOLENOID CONTROL CIRCUIT SHORT TO OTHER CIRCUITS
(T118) MS SOLENOID CONTROL CIRCUIT OPEN
(T118) MS SOLENOID CONTROL CIRCUIT SHORT TO GROUND

POWERTRAIN CONTROL MODULE
Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The Transmission Control System uses six electronically controlled solenoids that allow hydraulic fluid to be applied
to various friction elements (clutches), which enables the gear requested. The continuity of each solenoid circuit is
periodically tested. Each inactive solenoid is turned on for a few milliseconds, then off. Each active solenoid is
turned off for a few milliseconds, then on. This pulsing of voltage to the solenoid causes an inductive spike which
can be sensed by the Transmission Control System. If an inductive spike is not sensed by the Transmission Control
System during the continuity check, it is tested again. If the test fails three consecutive times, the appropriate Diag-
nostic Trouble Code (DTC) is set. If the solenoid test is run in response to agear ratio or pressure switch error, one
failure will result in setting the appropriate DTC.Note: This DTC is strictly an electrical fault and does not apply
to any internal transmission failures.

1.
Perform the following before attempting any diagnostic procedures:
Check the transmission fluid level. Ifthe fluid level is low, locate and repair any leaks and fill the transmission
to the proper level. Refer to the appropriate Service Information for procedures. Many transmission symptoms
can be caused by a low fluid level.
Check the battery. To avoid false diagnosis, testing should only be performed with the battery fully charged.
With the scan tool, read Engine (PCM) DTCs. If DTCs are present, refer to theDriveability Category and per-
form to the appropriate diagnostic procedure(s) before proceeding.
With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information.
Diagnose any Pending DTC as a matured DTC.
With the scan tool, read DTC EVENT DATA.Use this data to identify the conditions in which the DTC was set.
Performing a Battery Disconnect will clear all DTC EVENT DATA and reset alllearned Transmission values to
the default values, which may temporarily result in erratic shift schedules.
With the scan tool, perform the Shift Lever Position Test. If the test does not pass, refer to the diagnostic
procedure for P0706 Transmission Range Sensor Rationality.
For Gear Ratio Error DTCs, use the scan tool to view CVI Monitor data. Read and record the Clutch Volume
Index information.
Use the wiring diagram as a guide. Inspect the wiring and connectors related to this circuit. Repair as neces-
sary.
Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, after
driving under specific conditions and after diagnostic monitors have beenrun.

GEAR RATIOS
The 545RFE gear ratios are:
OPERATION
The 45RFE/545RFE offers full electronic control of all automatic up and downshifts, and features real-time adaptive
closed-loop shift and pressure control. Electronic shift and torque converter clutch controls help protect the trans-
mission from damage due to high temperatures, which can occur under severeoperating conditions. By altering shift
schedules, line pressure, and converter clutch control, these controls reduce heat generation and increase trans-
mission cooling.
To help reduce efficiency-robbing parasitic losses, the transmissions includes a dual-stage transmission fluid pump
with electronic output pressure control. Under most driving conditions,pump output capacity greatly exceeds that
which is needed to keep the clutches applied. The 45RFE/545RFE pump-pressure control system monitors input
torque and adjusts the pump pressure accordingly. The primary stage of thepump works continuously; the second
stage is bypassed when demand is low. The control system also monitors input and output speed and, if incipient
clutch slip is observed, the pressure control solenoid duty cycle is varied, increasing pressure in proportion to
demand.
A high-travel torque converter damper assembly allows earlier torque converter clutch engagement to reduce slip-
page. Needle-type thrust bearings reduce internal friction. The 45RFE/545RFE is packaged in a one-piece die-cast
aluminum case. To reduce NVH, the case has high lateral, vertical and torsional stiffness. It is also designed to
maximize the benefit of the structural dust cover that connects the bottomof the bell housing to the engine bed-
plate, enhancing overall power train stiffness. Dual filters protect thepump and other components. A cooler return
filter is added to the customary main sump filter. Independent lubrication and cooler circuits assure ample pressure
for normal transmission operation even if the cooler is obstructed or the fluid cannot flow due to extremely low
temperatures.
The hydraulic control system design (without electronic assist) provides the transmission with PARK, REVERSE,
NEUTRAL, SECOND, and THIRD gears, based solely on driver shift lever selection. This design allows the vehicle
to be driven (in “limp-in” mode) in the event of a electronic control systemfailure, or a situation that the Transmis-
sion Control Module (TCM) recognizes as potentially damaging to the transmission.
The TCM also performs certain self-diagnostic functions and provides comprehensive information (sensor data,
DTC’s, etc.) which is helpful in proper diagnosis and repair. This information can be viewed with the DRB
scan
tool.
DIAGNOSIS AND TESTING
AUTOMATIC TRANSMISSION
CAUTION: Before attempting any repair on a RFE automatic transmission, check for Diagnostic Trouble
Codes with the scan tool.
Transmission malfunctions may be caused by these general conditions:
Poor engine performance

Improper adjustments
Hydraulic malfunctions
Mechanical malfunctions
Electronic malfunctions
Diagnosis of these problems should always begin by checking the easily accessible variables: fluid level and con-
dition, gearshift cable adjustment. Then perform a road test to determineif the problem has been corrected or if
more diagnosis is necessary. If the problem persists after the preliminary tests and corrections are completed,
hydraulic pressure checks should be performed.
PRELIMINARY
Two basic procedures are required. One procedure for vehicles that are drivable and an alternate procedure for
disabled vehicles (will not back up or move forward).
VEHICLE IS DRIVABLE
1. Check for transmission fault codes using scan tool.
2. Check fluid level and condition.
3. Adjust gearshift cable if complaint was based on delayed, erratic, or harsh shifts.
4. Road test and note how transmission upshifts, downshifts, and engages.
5. Perform hydraulic pressure test if shift problems were noted during roadtest.
6. Perform air-pressure test to check clutch operation.
VEHICLE IS DISABLED
1. Check fluid level and condition.
2. Check for broken or disconnected gearshift cable.
3. Check for cracked, leaking cooler lines, or loose or missing pressure-port plugs.
4. Raise and support vehicle on safety stands, start engine, shift transmission into gear, and note following:
a. If propeller shaft turns but wheels do not, problem is with differentialor axle shafts.
b. If propeller shaft does not turn and transmission is noisy, stop engine.Remove oil pan, and check for debris.
If pan is clear, remove transmission and check for damaged driveplate, converter, oil pump, or input shaft.
c. If propeller shaft does not turn and transmission is not noisy, perform hydraulic-pressure test to determine if
problem is hydraulic or mechanical.
ROAD TESTING
Before road testing, be sure the fluid level and control cable adjustmentshave been checked and adjusted if nec-
essary. Verify that all diagnostic trouble codes have been resolved.
Observe engine performance during the road test. A poorly tuned engine will not allow accurate analysis of trans-
mission operation.
Operate the transmission in all gear ranges. Check for shift variations and engine flare which indicates slippage.
Note if shifts are harsh, spongy, delayed, early, or if part throttle downshifts are sensitive.
Slippage indicated by engine flare, usually means clutch, overrunning clutch, or line pressure problems.
A slipping clutch can often be determined by comparing which internal units are applied in the various gear ranges.
The Clutch Application charts provide a basis for analyzing road test results.
