ASSEMBLY
NOTE: Install all new seals and o-rings onto the input shaft and input hub. The o-rings on the input hub are
color coded. Be sure to install the correct o-ring in the correct location.
1. Check the transmission lubrication check valve (20) located in the input shaft using shop air. The valve should
only allow air flow in one direction. If the valve allows no air flow, or air flow in both directions, the valve will need
to be replaced.
2. Lubricate all seals with Mopar
ATF +4, Automatic Transmission Fluid, prior to installation.
3. Assemble the OD/reverse piston (15) onto the input clutch hub (1).
4. Assemble the input clutch retainer (13) onto the input clutch hub (1).

OPERATION
As the torque converter rotates, the converter hub rotates the oil pump drive gear. As the drive gear rotates both
driven gears, a vacuum is created when the gear teeth come out of mesh. This suction draws fluid through the
pump inlet from the oil pan. As the gear teeth come back into mesh, pressurized fluid is forced into the pump outlet
and to the oil pump valves.
At low speeds, both sides of the pump supply fluid to the transmission. As the speed of the torque converter
increases, the flow from both sides increases until the flow from the primary side alone is sufficient to meet system
demands. At this point, the check valve located between the two pumps closes. The secondary side is shut down
and the primary side supplies all the fluid to the transmission.
CONVERTER CLUTCH SWITCH VALVE
The converter clutch switch valve is used to control the hydraulic pressure supplied to the front (OFF) side of the
torque converter clutch.
CONVERTER CLUTCH REGULATOR VALVE
The converter clutch regulator valve is used to control the hydraulic pressure supplied to the back (ON) side of the
torque converter clutch.
TORQUE CONVERTER LIMIT VALVE
The torque converter limit valve serves to limit the available line pressure to the torque converter clutch.
STANDARD PROCEDURE - OIL PUMP VOLUME CHECK
Measuring the oil pump output volume will determine if sufficient oil flowto the transmission oil cooler exists, and
whether or not an internal transmission failure is present.
Verify that the transmission fluid is at the proper level. Refer to the Fluid Level Check procedure in this section. If
necessary, fill the transmission to the proper level with Mopar
ATF +4, Automatic Transmission Fluid.
1. Disconnect theTo coolerline at the cooler inlet and place a collecting container under the disconnected line.
CAUTION: With the fluid set at the proper level, fluid collection should not exceed (1) quart or internal dam-
age to the transmission may occur.
2. Run the engineat 1800 rpm, with the shift selector in neutral. Verify that the transmission fluid temperature is
below 104.5° C (220° F) for this test.
3. If one quart of transmission fluid is collected in the container in 30 seconds or less, oil pump flow volume is
within acceptable limits. If fluid flow is intermittent, or it takes more than 30 seconds to collect one quart of fluid,
refer to the Hydraulic Pressure tests in this section for further diagnosis.
4. Re-connect theTo c o o l e rline to the transmission cooler inlet.
5. Refill the transmission to proper level.

MECHANISM-SHIFT
DESCRIPTION
The gear shift mechanism provides six shift positions which are:
Park (P)
Reverse (R)
Neutral (N)
Drive (D)
Manual second (2)
Manual low (1)
OPERATION
MANUAL LOW (1) range provides first gear only. Overrun braking is also provided in this range. MANUAL SECOND
(2) range provides first and second gear only.
DRIVE range provides FIRST, SECOND, THIRD, OVERDRIVE FOURTH, and OVERDRIVE FIFTH (if applicable)
gear ranges. The shift into OVERDRIVE FOURTH and FIFTH (if applicable) gear ranges occurs only after the trans-
mission has completed the shift into D THIRD gear range. No further movement of the shift mechanism is required
to complete the 3-4 or 4-5 (if applicable) shifts.
The FOURTH and FIFTH (if applicable) gear upshifts occur automatically when the overdrive selector switch is in
the ON position. No upshift to FOURTH or FIFTH (if applicable) gears will occur if any of the following are true:
The transmission fluid temperature is below 10° C (50° F) or above 121° C (250° F).
The shift to THIRD is not yet complete.
Vehicle speed is too low for the 3-4 or 4-5 (if applicable) shifts to occur.
Upshifts into FOURTH or FIFTH (if applicable) will be delayed when the transmission fluid temperature is below 4.5°
C(40°F)orabove115.5°C(240°F).

TORQUE CONVERTER CLUTCH (TCC)
In a standard torque converter, the impeller and tur-
bine are rotating at about the same speed and the
stator is freewheeling, providing no torque multiplica-
tion. By applying the turbine’s piston and friction mate-
rial to the front cover, a total converter engagement
can be obtained. The result of this engagement is a
direct 1:1 mechanical link between the engine and the
transmission.
The clutch can be engaged in second, third, fourth,
and fifth (if appicable) gear ranges depending on over-
drive control switch position. If the overdrive control
switch is in the normal ON position, the clutch will
engage after the shift to fourth gear. If the control
switch is in the OFF position, the clutch will engage
after the shift to third gear.
The TCM controls the torque converter by way of
internal logic software. The programming of the soft-
ware provides the TCM with control over the L/R-CC
Solenoid. There are four output logic states that can
be applied as follows:
No EMCC
Partial EMCC
Full EMCC
Gradual-to-no EMCC
NO EMCC
Under No EMCC conditions, the L/R Solenoid is OFF. There are several conditions that can result in NO EMCC
operations. No EMCC can be initiated due to a fault in the transmission or because the TCM does not see the need
for EMCC under current driving conditions.
PARTIAL EMCC
Partial EMCC operation modulates the L/R Solenoid (duty cycle) to obtain partial torque converter clutch application.
Partial EMCC operation is maintaineduntil Full EMCC is called for and actuated. During Partial EMCC some slip
does occur. Partial EMCC will usually occur at low speeds, low load and light throttle situations.
FULL EMCC
During Full EMCC operation, the TCM increases the L/R Solenoid duty cycle to full ON after Partial EMCC control
brings the engine speed within the desired slip range of transmission input speed relative to engine rpm.
GRADUAL-TO-NO EMCC
This operation is to soften the change from Full or Partial EMCC to No EMCC. This is done at mid-throttle by
decreasing the L/R Solenoid duty cycle.
REMOVAL
1. Remove transmission and torque converter from vehicle. (Refer to 21 - TRANSMISSION/AUTOMATIC - 45RFE/
545RFE - REMOVAL)
2. Place a suitable drain pan under the converter housing end of the transmission.
CAUTION: Verify that transmission is secure on the lifting device or work surface, the center of gravity of
the transmission will shift when the torque converter is removed creatingan unstable condition. The torque
converter is a heavy unit. Use caution when separating the torque converter from the transmission.
3. Pull the torque converter forward until the center hub clears the oil pumpseal.
