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.
45RFE CLUTCH APPLICATION CHART

line pressure reading should match the gauge reading within ±10 psi.
In order to access any other pressure tap locations,
the transmission oil pan must be removed, the pres-
sure port plugs removed and Valve Body Pressure Tap
Adapter 8258-A (2) installed. The extensions supplied
with Adapter 8258-A will allow the installation of pres-
sure gauges to the valve body.
Refer to the Pressure Tap Locations graphic for cor-
rect pressure tap location identification.
TEST PROCEDURE
All pressure readings should be taken with the transmission fluid level full, transmission oil at the normal operating
temperature, and the engine at 1500 rpm. Check the transmission for properoperation in each gear position that is
in question or if a specific element is in question, check the pressure readings in at least two gear positions that
employ that element. Refer to the Hydraulic Schematics at the rear of this section to determine the correct pres-
sures for each element in a given gear position.
NOTE: The 45RFE/545RFE utilizes closed loop control of pump line pressure. The pressure readings may
therefore vary greatly but should always follow line pressure.
Some common pressures that can be measured to evaluate pump and clutch performance are the upshift/downshift
pressures, garage shift pressures, and TCC pressure. The upshift/downshift pressure for all shifts are shown in
UPSHIFT PRESSURES and DOWNSHIFT PRESSURES . In-gear maximum pressure foreach gear position is
shown in IN-GEAR PRESSURES . The garageshift pressure when performing a N-R shift is 220 psi for 3.7L/4.7L
equipped vehicles and 250 psi for 5.7L equipped vehicles. The garage shiftpressure for the R-N shift is 120 psi.
The garage shift pressure for the N-1 shift is 135 psi for 3.7L/4.7L equipped vehicles and 165 psi for 5.7L equipped

vehicles. Torque converter lock-up pressure is 120 psi for 3.7L/4.7L equipped vehicles and 125 psi for 5.7L
equipped vehicles.

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

NOTE: Before final assembly of transmission cen-
terline, the 2C/4C clutch components should be
installed into position and measured as follows:
9. Install the 2C reaction plate (4) into the transmis-
sion case.
10. Install the 2C clutch pack (2, 3) into the transmis-
sion case.
11. Install the flat 2C clutchsnap-ring(1)intothe
transmission case.
12. Install the 4C retainer/bulkhead (2) into the trans-
mission case. Make sure that the oil feed holes
are pointing toward the valve body area.
13. Install the 4C retainer/bulkhead tapered snap-ring
(1) into the transmission case. Make sure that the
open ends of the snap-ring are located in the
case opening toward the valve body area.
14. Using a feeler gauge through the opening in the
rear of the transmission case, measure the 2C
clutch pack clearance between the 2C reaction
plate and the transmission case at four different
points. The average of these measurements is the
2C clutch pack clearance. The correct clutch
clearance is 0.455-1.335 mm (0.018-0.053 in.).
The reaction plate is not selective. If the clutch
pack clearance is not within specification, the
reaction plate, all the friction discs, and steels
must be replaced.
15. Remove the 4C retainer/bulkhead and all of the
2C clutch components from the transmission case.
16. Install the low/reverse clutch assembly (1). Make
sure that the oil feed hole points toward the valve
body area and that the bleed orifice is aligned
with the notch in the rear of the transmission
case.
17. Install the snap-ring (2) to hold the low/reverse
clutch retainer into the transmission case. The
snap-ring is tapered and must be installed with
the tapered side forward. Once installed, verify
that the snap-ring is fully seated in the snap-ring
groove.
18. Air check the low/reverse clutch and verify correct
overrunning clutch operation.

31. Install the number 6 thrust bearing (7) against the output shaft selective thrust plate (6) with the flat side against
the thrust plate and the raised tabs on the inner race facing the front of thetransmission.
32. Install the reaction annulus (8) into the reaction planetary gear set.
33. Install the 4C retainer/bulkhead (2) into the trans-
mission case. Make sure that the oil feed holes
are pointing toward the valve body area. Rotate
the reaction annulus during the installation of the
4C retainer/bulkhead to ease installation.
34. Install the 4C retainer/bulkhead tapered snap-ring
(1) into the transmission case with the taper
toward the front of the case. Make sure that the
open ends of the snap-ring are located in the
case opening toward the valve body area.
35. Air check the 2C and 4C clutch operation.

INSTALLATION
1. Check torque converter hub and hub drive flats for
sharp edges burrs, scratches, or nicks. Polish the
hub and flats with 320/400 grit paper and crocus
cloth if necessary. Verify that the converter hub
o-ring is properly installed and is free of any debris.
The hub must be smooth to avoid damaging pump
seal at installation.
2. If a replacement transmission is being installed,
transfer any components necessary, such as the
manual shift lever and shift cable bracket, from the
original transmission onto the replacement trans-
mission.
3. Lubricate oil pump seal lip with transmission fluid.
4. Align converter and oil pump.
5. Carefully insert converter in oil pump. Then rotate
converter back and forth until fully seated in pump
gears.
6. Check converter seating with steel scale (1) and
straightedge (2). Surface of converter lugs should
be at least 13mm (1/2 in.) to rear of straightedge when converter is fully seated.
7. Temporarily secure converter with C-clamp.
8. Position transmission on jack and secure it with
chains.
9. Check condition of converter driveplate. Replace
the plate if cracked, distorted or damaged.Also be
sure transmission dowel pins are seated in
engine block and protrude far enough to hold
transmission in alignment.
10. Apply a light coating of Mopar
High Temp
Grease to the torque converter hub pocket in the
rear pocket of the engine’s crankshaft.
11. Raise transmission (2) and align the torque con-
verter with the drive plate and transmission con-
verter housing with the engine block.
12. Move transmission forward. Then raise, lower or
tilt transmission to align the converter housing
with engine block dowels.
13. Carefully work transmission forward and over
engine block dowels until converter hub is seated
in crankshaft. Verify that no wires, or the transmis-
sion vent hose, have become trapped between
theengineblockandthetransmission.
14. Install two bolts to attach the transmission to the
engine.
15. Install remaining torque converter housing to
engine bolts. Tighten to 68 Nꞏm (50 ft.lbs.).
