(2) Disconnect CKP electrical connector at sensor
(Fig. 22).
(3) Remove CKP mounting bolt (Fig. 23).
(4) Carefully twist sensor from cylinder block.(5) Remove sensor from vehicle.
(6) Check condition of sensor o-ring.
INSTALLATION
INSTALLATION - 4.0L
The Crankshaft Position (CKP) sensor is mounted
to the transmission bellhousing at the left/rear side
of the engine block (Fig. 21). The sensoris adjust-
ableand is attached with one bolt. A wire shield/
router is attached to the sensor (Fig. 21).
New replacement sensors will be equipped with a
paper spacer glued to bottom of sensor. If installing
(returning) ausedsensor to vehicle, a new paper
spacer must be installed to bottom of sensor. This
spacer will be ground off the first time engine is
started. If spacer is not used, sensor will be broken
the first time engine is started.
(1) New Sensors: Be sure paper spacer is installed
to bottom of sensor. If not, obtain spacer
PN05252229.
(2) Used Sensors: Clean bottom of sensor and
install spacer PN05252229.
(3) Install sensor into transmission bellhousing
hole.
(4) Position sensor wire shield to sensor (Fig. 21).

(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. 52). Surface of converter lugs
should be at least 13 mm (1/2 in.) to rear of straight-
edge 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 MopartHigh Temp
Grease to the torque converter hub pocket in the rear
pocket of the engine's crankshaft.
(11) Raise transmission and align the torque con-
verter with the drive plate and the transmission con-
verter housing with the engine block.
(12) Move transmission forward. Then raise, lower,
or tilt transmission to align the converter housing
with the 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 transmission
vent hose, have become trapped between the engine
block and the transmission.
(14) Install two bolts to attach the transmission to
the 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) Install new plastic retainer grommet on any
shift cable that was disconnected. Grommets should
not be reused. Use pry tool to remove rod from grom-
met and cut away old grommet. Use pliers to snap
new grommet into cable and to snap grommet onto
lever.
(21) Connect gearshift cable to transmission.
(22) Connect wires to solenoid and pressure switch
assembly connector, input and output speed sensors,
and line pressure sensor. Be sure transmission har-
nesses are properly routed.
CAUTION: It is essential that correct length bolts be
used to attach the converter to the driveplate. Bolts
that are too long will damage the clutch surface
inside the converter.
(23) Install all torque converter-to-driveplate bolts
by hand.
(24) Verify that the torque converter is pulled
flush to the driveplate. Tighten bolts to 31 N´m (270
in. lbs.).
(25) Install starter motor and cooler line bracket.
(26) Connect cooler lines to transmission.
(27) Install transmission fill tube.
(28) Install exhaust components.
(29) Install transfer case. Tighten transfer case
nuts to 35 N´m (26 ft.lbs.).
(30) Install the transfer case shift cable to the
cable support bracket and the transfer case shift
lever.
(31) Install the transmission collar onto the trans-
mission and the engine. Tighten the bolts to 54 N´m
(40 ft.lbs.).
(32) Align and connect propeller shaft(s).
(33) Adjust gearshift cable if necessary.
(34) Lower vehicle.
(35) Fill transmission with MopartATF +4, type
9602, Automatic Transmission fluid.
