INSTALLATION
(1) Check torque converter hub and hub drive
notches for sharp edges burrs, scratches, or nicks.
Polish the hub and notches with 320/400 grit paper
and crocus cloth if necessary. 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 and
straightedge (Fig. 46). Surface of converter lugs
should be 1/2 in. to rear of straightedge when con-
verter 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
t High Temp
Grease to the torque converter hub pocket in the rear
(11) Raise transmission and align converter with
drive plate and converter housing with engine block.

REMOVAL AND INSTALLATION (Continued)
(12) Move transmission forward. Then raise, lower
or tilt transmission to align converter housing with
engine block dowels.
(13) Carefully work transmission forward and over
engine block dowels until converter hub is seated in
crankshaft.
(14) Install two bolts to attach converter housing
to engine.
(15) Install remaining torque converter housing to
engine bolts. Tighten to 68 N·m (50 ft.lbs.).
(16) Install
rear
transmission
crossmember.
Tighten crossmember to frame bolts to 68 N·m (50
ft.lbs.).
(17) Install rear support to transmission. Tighten
bolts to 47 N·m (35 ft.lbs.).
(18) Lower transmission onto crossmember and
install bolts attaching transmission mount to cross-
member. Tighten clevis bracket to crossmember bolts
to 47 N·m (35 ft.lbs.). Tighten the clevis bracket to
rear support bolt to 68 N·m (50 ft.lbs.).
(19) Remove engine support fixture.
(20) Connect gearshift cable to transmission.
(21) Connect wires to solenoid and pressure switch
assembly connector, input and output speed sensors,

TORQUE CONVERTER
REMOVAL
(1) Remove transmission and torque converter
from vehicle.
(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 con-
verter is removed creating an 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 cen-
ter hub clears the oil pump seal.
(4) Separate the torque converter from the trans-
mission.
INSTALLATION
Check converter hub and drive notches for sharp
edges, burrs, scratches, or nicks. Polish the hub and
notches with 320/400 grit paper or crocus cloth if nec-
essary. The hub must be smooth to avoid damaging
the pump seal at installation. Check that the torque
converter hub o-ring on the 45RFE torque converter
hub is not damaged. Replace if necessary.
(1) Lubricate oil pump seal lip with transmission
fluid.
(2) Place torque converter in position on transmis-
sion.

C-clamp attached to the converter housing.
(8) Install the transmission in the vehicle.
(9) Fill the transmission with the recommended
fluid.
