63. On 4X2 transmissions, perform the following, if necessary:
a. Install the extension shaft bearing (2) onto the
extension shaft.
b. Install the extension shaft bearing retaining ring
(3) onto the extension shaft (1).
c. Install the extension shaft (2) and bearing
assembly (3) into the extension housing (1).

d.
Install the extension shaft bearing snap ring (3)
into the extension housing.
e. Verify that the extension shaft snap ring (3) is
fully engaged in the snap ring groove.
64. Inspect the lube tube grommet (3) for damage. If
the grommet lip is damaged, it will need to be
replaced.

65. Install the 4X4 stub shaft onto the transmission
output shaft.
66. Place a bead of Mopar
ATF RTV on the rear sur-
face of the transmission case for the adapter/ex-
tension housing.
67. Install the adapter housing (2) onto the transmis-
sion case, 4X4 vehicles only.
68. Install the extension housing (2) onto the trans-
mission case, 4X2vehicles only.
NOTE: Before installing thelowermost four adapt-
er/extension housing bolts , it will be necessary to
replenish the sealing patch on the bolts using
MOPAR
Lock & Seal Adhesive.

69. Install the bolts that hold the adapter or extension
housing onto the transmission case. Be sure to
install any stud bolts to their original locations.
Tighten the bolts to 54 Nꞏm (40 ft.lbs.).
INSTALLATION
NOTE: 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. Thehub must be smooth to avoid
damaging pump seal at installation.
1. 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 transmission.
2. Lubricate oil pump seal lip with transmission fluid.
3. Align converter and oil pump.
4. Carefully insert converter in oil pump. Then rotate
converter back and forth until fully seated in pump
gears.
5. 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.
6. Temporarily secure converter with C-clamp.
7. Position transmission on jack and secure it with chains.
8. Check condition of converter driveplate. Replace the plate if cracked,distorted or damaged.Also be sure trans-
mission dowel pins are seated in engine block and protrude far enough to holdtransmissioninalign-
ment.
9. Apply a light coating of Mopar
High Temp Grease to the torque converter hub pocket in the rear pocket of the
engine’s crankshaft.
10. Raise transmission and align the torque converter with the drive plateand transmission converter housing with
the engine block.
11. Move transmission forward. Then raise, lower or tilt transmission to align the converter housing with engine
block dowels.
Page 2973 of 5267

12. 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.
13. Install two bolts to attach the transmission to the engine.
14. Install remaining torque converter housing to engine bolts. Tighten to 68 Nꞏm (50 ft.lbs.).
15. Install transfer case, if equipped. Tighten transfer case nuts to 35 Nꞏm (26 ft.lbs.).
16. Install rear transmission crossmember. Tighten crossmember to framebolts to 68 Nꞏm (50 ft.lbs.).
17. Install rear support to transmission. Tighten bolts to 47 Nꞏm (35 ft.lbs.).
18. Lower transmission onto crossmember and install bolts attaching transmission mount to crossmember. Tighten
clevis bracket to crossmember bolts to 47 Nꞏm (35 ft.lbs.). Tighten the clevis bracket to rear support bolt to 68
Nꞏm (50 ft.lbs.).
19. Connect gearshift cable (1) to support bracket (2)
and transmission manual lever (3).
20. Connect the input (1) and output (2) speed sensor
and the transmission range sensor (5).
21. Connect the variable line pressure connector (4),
if equipped.

22. Connect wires to the solenoid/pressure switch
assembly (1).
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 sur-
face inside the converter.
23. Install torque converter-to-driveplate bolts. Tighten
boltsto88Nꞏm(65in.lbs.).
24. Install starter motor and cooler line bracket.
25. Connect cooler lines (1) to transmission.
26. Install transmission fill tube.
27. Install exhaust components (1).

28. Align and connect propeller shaft(s).
29. Adjust gearshift cable if necessary.
30. Install any skid plates removed previously. (Refer
to 13 - FRAMES & BUMPERS/FRAME/TRANS-
FER CASE SKID PLATE - INSTALLATION)
31. Lower vehicle.
32. Fill transmission with Mopar
AT F + 4 , A u t o m a t i c
Transmission Fluid.
