lightly to 50 MPH, then brake lightly to a stop. Turn off engine.
With the scan tool, record Transmission CL VOL INDEX (CVI) for all clutches.
With the scan tool, perform a BATTERY DISCONNECT.
With the scan tool, read the CVI’s and compare them to the reading recorded before the BATTERY DISCONNECT.
Are any of the CVI’s less than 5 or are they different than before the batterydisconnect?

Using the schematics as a guide, check the Powertrain Control Module (PCM)terminals for corrosion,
damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems
are found, replace the PCM per the Service Information. With the scan tool,perform QUICK LEARN.

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

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.
Diagnostic Test
1.RELATED TCM POWER INPUT DTCS PRESENT
With the scan tool, check for other transmission DTCs.
Are there any TCM Power Input DTCs present?

2.TRANSMISSION SOLENOID/TRS ASSEMBLY
Turn the ignition off to the lock position.
Remove the Ignition Switch Feed fuse from the TIPM.
CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being
startedingear.
WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in
personal injury or death.
Install Transmission Simulator, Miller tool #8333.
Ignition on, engine not running.
With the scan tool, actuate the MS Solenoid.

AIR CHECKING TRANSMISSION CLUTCH OPERATION
Air-pressure testing can be used to check transmis-
sion clutch operation. The test can be conducted with
the transmission either in the vehicle or on the work
bench, as a final check.
Air-pressure testing requires that the oil pan and valve
body be removed from the transmission. The clutch
apply passages are shown in the Air Pressure Test
Passages graphic.
NOTE: The air supply which is used must be free
ofmoistureanddirt.Useapressureof30psito
test clutch operation.
Apply air pressure at each port. If the clutch is func-
tioning, a soft thump will be heard as the clutch is
applied. The clutch application can also be felt by
touching the appropriate element while applying air
pressure. As the air pressure is released, the clutch
should also release.
CONVERTER HOUSING FLUID LEAK
When diagnosing converter housing fluid leaks, two items must be established before repair.
1. Verify that a leak condition actually exists.
2. Determined the true source of the leak.
1 - LOW REVERSE CLUTCH
2 - 4TH CLUTCH
3 - 2ND CLUTCH
4-OVERDRIVECLUTCH
5 - UNDERDRIVE CLUTCH
6 - REVERSE CLUTCH

8. Remove the exhaust support bracket from the rear
of the transmission.
9. Disconnect and lower or remove any necessary
exhaust components.
10. Remove the starter motor.
11. Rotate crankshaft in clockwise direction until con-
verter bolts are accessible. Then remove bolts
one at a time. Rotate crankshaft with socket
wrench on dampener bolt.
12. Disengage the output speed sensor connector
from the output speed sensor (2).
13. Disengage the input speed sensor connector from
the input speed sensor (2).
14. Disengage the transmission solenoid/TRS assem-
bly connector from the transmission solenoid/TRS
assembly (2).

15. Disengage the line pressure sensor connector
from the line pressure sensor (2).
16. Disconnect gearshift cable (1) from transmission
manual valve lever (3).
17. Disconnect the transmission vent hose from the
transmission.
18. Support rear of engine with safety stand or jack.
19. Raise transmission slightly with service jack to
relieve load on crossmember and supports.
20. Remove bolts securing rear support and cushion
to transmission and crossmember.
21. Remove transfer case, if necessary.
22. Disconnect transmission fluid cooler lines at trans-
mission fittings and clips.
23. Remove all remaining converter housing bolts.
24. Carefully work transmission and torque converter
assembly rearward off engine block dowels.
25. Hold torque converter in place during transmission
removal.
26. Lower transmission (2) and remove assembly from under the vehicle.
27. To remove torque converter, carefully slide torque converter out of the transmission.

NOTE: Do not use shop towels or rags to dry the case (or any other transmission component) unless they
aremadefromlint-freematerials.Lintwillsticktocasesurfacesandtransmission components and circu-
late throughout the transmission after assembly. A sufficient quantity of lint can block fluid passages and
interfere with valve body operation.
INSPECTION
Inspect the case for cracks, porous spots, worn bores, or damaged threads.Damaged threads can be repaired with
Helicoil
thread inserts. However, the case will have to be replaced if it exhibits any type of damage or wear.
ASSEMBLY
NOTE: Clean and inspect all components. Replace any components which showevidence of excessive wear
or scoring.
1. Install the cooler filter bypass valve. Torque the
bypass valve to specification. The valve uses a
tapered pipe thread and excessive torque can
damage the transmission case. Tighten the cooler
filter bypass valve to 4.5 Nꞏm (40 in.lbs.).
2. Install a new selector shaft seal (1) using Seal
Installer 8253 (2).
3. Install the manual selector shaft and retaining
screw. Tighten the manual selector shaft retaining
screw to 28 Nꞏm (250 in.lbs.).
4. Install the manual shift lever (1) onto the manual
selector shaft. Torque the retaining cross-bolt to 16
Nꞏm (140 in.lbs.).
