Installation
1) To install, reverse removal procedure. Ensure torque
converter is fully seated in transmission by measuring distance from
cylinder block surface on transmission housing to front edge on torque
converter bolt lug on front of torque converter. Distance should be .
50" (12.7 mm) if torque converter is fully seated.
CAUTION: Proper length torque converter bolts must be used. If
replacing any torque converter bolts, ensure proper length
bolt is used.
2) Tighten bolt/nuts to specification. See TORQUE
SPECIFICATIONS. Ensure reference mark on torque converter and
flexplate, and drive shaft flanges are aligned. Adjust shift cable or
linkage, throttle valve cable and transfer case shift linkage if
necessary. See AUTOMATIC TRANSMISSION - TRUCKS & RWD VANS article.
3) Use NEW "O" ring when installing dipstick tube. Before
installing oil cooler lines on transmission, ensure all fittings are
clean. Install oil cooler line into quick-disconnect fitting. Push oil
cooler line inward until a click is heard. Pull on oil cooler line to
ensure oil cooler line is locked in place. Fill transmission with
Mopar ATF Plus Type 7176.

Removal
1) Disconnect negative battery cable. Raise and support
vehicle. Disconnect and remove necessary skid plates and exhaust
components for transmission removal. Remove engine-to-transmission
struts (if equipped). These struts are located between front of
transmission and engine.
2) Ensure area around transmission oil cooler lines fitting
are clean. Disengage retainer on quick-disconnect cooler line fitting.
Pull cooler line from transmission oil cooler. Remove starter.
CAUTION: On 3.9L, 5.2L and 5.9L gasoline models, crankshaft position
sensor must be removed from transmission housing before
removing transmission to prevent damage to crankshaft
position sensor.
3) On 3.9L, 5.2L and 5.9L gasoline models, disconnect
electrical connector for crankshaft position sensor. Crankshaft
position sensor is mounted on passenger's side of transmission
housing. See Fig. 2.
4) Remove crankshaft position sensor bolts. Remove crankshaft
position sensor from transmission housing. Remove dipstick, dipstick
tube and "O" ring from transmission.
5) Remove torque converter cover. Place reference mark on
flexplate and torque converter for installation reference. Rotate
crankshaft clockwise and remove torque converter bolts.
6) Place reference mark on drive shaft flanges for
installation reference. Remove drive shaft from transmission. On 4WD
models, disconnect drive shaft from transfer case. Disconnect shift
rod for transfer case from transfer case shift lever.
7) On all models, disconnect necessary control cables, wiring
harnesses, and shift linkage from transmission. Support rear of engine
with jack stand. Using transmission jack, slightly raise transmission
to release pressure from rear mount and rear crossmember.
8) Remove bolts securing rear support and rear mount to
transmission and rear crossmember. Raise transmission slightly. Slide
exhaust hanger arm from bracket on rear support. Remove rear support
Page 1491 of 1691

and rear mount.
9) Remove rear crossmember located below the transmission. On
4WD models, disconnect electrical connectors from transfer case. On
all models, remove transmission-to-cylinder block bolts. Slide
transmission rearward from dowels on cylinder block.
10) Install "C" clamp on edge of transmission housing to hold
torque converter in place. Lower transmission and remove transmission

flexplate and torque converter for installation reference. Rotate
crankshaft clockwise and remove torque converter bolts.
6) Place reference mark on drive shaft yokes for installation
reference. Remove drive shaft from transmission. Disconnect necessary
wiring harnesses and control cables from transmission. Support rear of
engine with hoist. Using transmission jack, slightly raise
transmission to release pressure from rear mount and crossmember.
7) Remove rear mount-to-rear crossmember bolts. Remove bolts
and rear crossmember located below the transmission. Remove engine oil

Check transmission fluid level when performing other
underhood services. Under normal service conditions or severe service
conditions change transmission fluid, adjust bands and replace
transmission filter at specified interval. See TRANSMISSION SERVICING
INTERVALS table. Severe service conditions are conditions such as long
periods of engine idling, trailer towing, off-highway operation, snow
removal, or operating in dusty or excessively hot conditions.
