system problem is present. This test will determine if
the power steering pump or power steering gear is not
functioning properly. The following pressure and flow
test is performed using Power Steering Analyzer Tool
kit 6815 and Adapter Kit 6893.

The 42RLE is a four-speed transmission that is a conventional hydraulic/mechanical assembly controlled with adap-
tive electronic controls and monitors. The hydraulic system of the transmission consists of the transmission fluid,
fluid passages, hydraulic valves, and various line pressure control components. An input clutch assembly which
houses the underdrive, overdrive, and reverse clutches is used. It also utilizes separate holding clutches: 2nd/4th
gear and Low/Reverse. The primary mechanical components of the transmission consist of the following:
Three multiple disc input clutches
Two multiple disc holding clutches
Four hydraulic accumulators
Two planetary gear sets
Hydraulic oil pump
Valve body
Solenoid/Pressure switch assembly
Control of the transmission is accomplished by fully adaptive electronics. Optimum shift scheduling is accomplished
through continuous real-time sensor feedback information provided to the Transmission Control Module (TCM) por-
tion of the Powertrain Control Module (PCM).
The TCM is the heart of the electronic control system and relies on information from various direct and indirect
inputs (sensors, switches, etc.) to determine driver demand and vehicle operating conditions. With this information,
the TCM can calculate and perform timely and quality shifts through various output or control devices (solenoid
pack, transmission control relay, etc.).
The TCM also performs certain self-diagnostic functions and provides comprehensive information (sensor data,
DTC’s, etc.) which is helpful in proper diagnosis and repair. This informationcanbeviewedwiththescantool.
TRANSMISSION IDENTIFICATION
The 42RLE transmission can be identified by a bar-
code label that is affixed to the upper left area of the
bellhousing.
The label contains a series of digits that can be trans-
lated into useful information such as transmission part
number (10), date of manufacture (4, 5), manufactur-
ing origin (2), assembly line identifier (6), build
sequence number (7), etc..
If the tag is not legible or is missing, the “PK” number,
which is stamped into the left rear flange of the trans-
mission case, can be referred to for identification. The
entire part number, build code, and sequence number
are stamped into the flange.
OPERATION
The 42RLE transmission ratios are:
1 - DRIVEPLATE 6 - REVERSE CLUTCH 11 - STUB SHAFT
2 - TORQUE CONVERTER 7 - FRONT PLANET CARRIER 12 - LOW/REVERSE CLUTCH
3 - INPUT SHAFT 8 - REAR PLANET CARRIER 13 - 2/4 CLUTCH
4 - UNDERDRIVE CLUTCH 9 - OUTPUT SHAFT 14 - OIL PUMP
5 - OVERDRIVE CLUTCH 10 - SNAP RING

6. Install new seals (6, 16) on clutch piston (15). Be sure lip of each seal faces interior of clutch retainer.
7. Lubricate lip of piston seals with generous quantity of Mopar
Door Ease. Then lubricate retainer (1) hub and
bore with light coat of transmission fluid.
8. Install clutch piston (15) in retainer (1). Use twisting motion to seat piston in bottom of retainer. A thin strip of
plastic (about 0.020
thick), can be used to guide seals into place if necessary.
CAUTION: Never push the clutch piston straight in. This will fold the sealsover causing leakage and clutch
slip. In addition, never use any type of metal tool to help ease the piston seals into place. Metal tools will
cut, shave, or score the seals.
9. Install piston spring (7) in retainer (1) and on top of piston (15). Concave side of spring faces downward (toward
piston).
10. Install the spacer ring (14) and wave spring (13) into the retainer. Be sure spring is completely seated in
retainer groove.
11. Install pressure plate (8). Ridged side of plate faces downward (toward piston) and flat side toward clutch pack.
12. Install first clutch disc (9) in retainer on top of pressure plate. Theninstall a clutch plate (12) followed by a
clutch disc until entire clutch pack is installed (4 discs and 3 plates are required) .
13. Install the reaction plate (11).
14. Install selective snap-ring (10). Be sure snap-ring is fully seated inretainer groove.

engaged in 4LO position.1) While rolling 2-3 MPH and the
transmission in NEUTRAL, or the
clutch depressed on vehicles
equipped with a manual
transmission, shift the transfer case

then back into the 4LO position.
2) Range fork damaged, inserts
worn, or fork is binding on the shift
rail.2) Repair or replace components as
necessary.

damaged.3) Repair or replace components as
necessary.
Lubricant leaking from transfer case
seals or vent.1) Transfer case overfilled. 1) Drain lubricant to the correct
level.
2) Transfer case vent closed or
restricted.2) Clean or replace vent as
necessary.
3) Transfer case seals damaged or
installed incorrectly.3) Replace suspect seal.
Transfer case will not shift through
4LOCK (Part-time) range.1) Incomplete shift due to drivetrain
torque load.1)Driveinastraightlineand
momentarily release the accelerator
pedal to complete the shift.

Radial-ply tires have the same load-carrying capacity as other types of tires of the same size. They also use the
same recommended inflation pressures.
The use of oversized tires, either in the front or rear of the vehicle, can cause vehicle drive train failure. This could
also cause inaccurate wheel speed signals when the vehicle is equipped with Anti-Lock Brakes.
The use of tires from different manufactures on the same vehicle is NOT recommended. The proper tire pressure
should be maintained on all four tires.
TIRE PRESSURE FOR HIGH SPEEDS
For proper tire pressure specification refer to the Owners Manual.
REPLACEMENT TIRES
The original equipment tires provide a proper balance of many characteristics such as:
Ride
Noise
Handling
Durability
Tread life
Traction
Rolling resistance
Speed capability
It is recommended that tires equivalent to the original equipment tires beused when replacement is needed.
Failure to use equivalent replacement tires may adversely affect the safety and handling of the vehicle.
The use of oversize tires may cause interference with vehicle components.Under extremes of suspension and
steering travel, interference with vehicle components may cause tire damage.
WARNING: Failure to equip the vehicle with tires having adequate speed capability can result in sudden tire
failure.
TIRE INFLATION PRESSURES
WARNING: Over or under inflated tires can affect
vehicle handling and tread wear. This may cause
the tire to fail suddenly, resulting in loss of vehicle
control.
Under inflation will cause rapid shoulder wear (1), tire
flexing, and possible tire failure.
