AUTOMATIC TRANSMISSION 42RLE - SERVICE INFORMATION

21 - 175

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 information can be viewed with the scan tool.

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.
