Jeep Grand Cherokee WK. Manual — part 1403
2. Install the park lock cable (4) to the ignition cylinder
(3). Secure the cable to instrument panel at
retainer.
3. Install any instrument panel trim that was removed
to access the park lock cable.
4. Route park lock cable towards shift mechanism.
5. Connect the park lock cable (5) core to shift mech-
anism cam, and then secure cable housing to shift
mechanism.
6. Adjust the park lock cable. (Refer to 21 - TRANSMISSION/AUTOMATIC TRANSMISSION/SHIFT INTERLOCK
MECHANISM - ADJUSTMENTS)
7. If necessary, install the shield, covering the gearshift and park lock cables, to the shifter assembly and install the
bolts to hold the shield to the shifter assembly.
8. Install the floor console assembly. (Refer to 23 - BODY/INTERIOR/FLOOR CONSOLE - INSTALLATION)

GEARTRAIN-PLANETARY
DESCRIPTION
The planetary geartrain is located behind the 4C retainer/bulkhead, toward the rear of the transmission. The plan-
etary geartrain consists of three primary assemblies:
•
Reaction (3, 4, 8).
Reaction Planetary Geartrain
1 - THRUST BEARING NUMBER 8
5 - THRUST BEARING NUMBER 7
2 - THRUST BEARING NUMBER 9
6 - THRUST PLATE (SELECT)
3 - REACTION PLANETARY CARRIER
7 - THRUST BEARING NUMBER 6
4 - REACTION SUN GEAR
8 - REACTION ANNULUS

•
Reverse (7).
•
Input (4, 5, 6).
OPERATION
REACTION PLANETARY GEARTRAIN
The reaction planetary carrier and reverse sun gear of the reaction planetary geartrain are a single component
which is held by the 2C clutch when required. The reaction annulus gear is a stand alone component that can be
driven by the reverse clutch or held by the 4C clutch. The reaction sun gear is driven by the overdrive clutch.
REVERSE PLANETARY GEARTRAIN
The reverse planetary geartrain is the middle of the three planetary sets. The reverse planetary carrier can be
driven by the overdrive clutch as required. The reverse planetary carrier is also splined to the input annulus gear,
which can be held by the low/reverse clutch. The reverse planetary annulus, input planetary carrier, and output shaft
are all one piece.
INPUT PLANETARY GEARTRAIN
The input sun gear of the input planetary geartrain is driven by the underdrive clutch.
Reverse/Input Planetary Geartrain
1 - SNAP-RING
5 - INPUT PLANETARY CARRIER
2 - THRUST BEARING NUMBER 10
6 - INPUT SUN GEAR
3 - THRUST BEARING NUMBER 11
7 - REVERSE PLANETARY CARRIER
4 - INPUT ANNULUS

DISASSEMBLY
1. Remove the snap-ring (1) holding the input annulus (4) into the input carrier (5).
2. Remove the input annulus (4) from the input carrier (5).
3. Remove the number 9 thrust bearing from the reverse planetary carrier. Note that this planetary carrier has four
pinion gears.
4. Remove the reverse planetary gear carrier (7).
5. Remove the number 10 thrust bearing (2) from the input sun gear (6).
6. Remove the input sun gear (6) from the input carrier (5).
7. Remove the number 11 thrust bearing (3) from the input carrier (5).
CLEANING
Clean the planetary components in solvent and dry them with compressed air.
INSPECTION
Check sun gear and driving shell condition. Replace the gear if damaged or if the bushings are scored or worn. The
bushings are not serviceable. Replace the driving shell if worn, cracked or damaged.
Replace planetary gear sets if gears, pinion pins, or carrier are damaged in any way. Replace the annulus gears
and supports if either component is worn or damaged.
Replace the output shaft if the machined surfaces are scored, pitted, or damaged in any way. Also replace the shaft
if the splines are damaged, or exhibits cracks at any location.
