Theory of Operation
The Solenoid Switch Valve, an internal, hydraulically operated valve, controls the direction of the transmission fluid
when the LR solenoid is energized. When the solenoid switch valve is in the downshifted position and the LR sole-
noid is energized, fluid is directed to the LR element for 1st gear. When thesolenoid switch valve is In the up-
shifted position (2nd, 3rd, and 4th gear) and the LR solenoid is energized,fluidisdirectedintotheLockupSwitch
Valve which controls the Torque Converter Clutch. When shifting into 1st gear, a special sequence is followed to
insure solenoid switch valve movement into the downshifted position. TheLR pressure switch is monitored to con-
firm switch valve movement. If the solenoid switch valve movement is not confirmed (i.e. no LR pressure when the
LR solenoid is energized), 2nd gear is substituted for 1st. No 1st gear (2ndgear is substituted). The transmission
Torque converter FEMCC operation is inhibited. MIL on after 5 min. of substituted operation.

Theory of Operation
The Solenoid Switch Valve, an internal, hydraulically operated valve, controls the direction of the transmission fluid
when the L/R solenoid is energized. When the solenoid switch valve is in thedownshifted position and the L/R
solenoid is energized, fluid is directed to the L/R element for 1st gear. When the solenoid switch valve is In the
up-shifted position (2nd, 3rd, and 4th gear) and the L/R solenoid is energized, fluid is directed into the Lockup
Switch Valve which controls the Torque Converter Clutch. When doing PEMCCor FEMCC, the L/R pressure switch
should indicate no pressure if the solenoid switch valve is in the L/R position. If the L/R pressure switch indicates
pressure for some time while in partial or full EMCC, the EMCC operation is aborted and momentarily inhibited to
avoid accidental application of the L/R clutch. EMCC is attempted again when there is no L/R pressure. The fourth
detection of L/R pressure while in PEMCC or FEMCC will result in setting theDTC. Torque converter EMCC oper-
ation inhibited. MIL on after 5 min. of substituted operation.

P1797-MANUAL SHIFT OVERHEAT
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Continuously with engine running.
Set Condition:
If the Engine Temperature exceeds 123° C (255° F) or the Transmission Temperature exceeds 135° C (275° F)
while in AutoStick
mode. Note: Aggressive driving or driving in low for extended periods of time will set this
DTC.
Possible Causes
MANUAL SHIFT OVERHEAT
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The major cause of heat build up in the transmission is torque converter slip.WiththetransmissionintheAuto-
Stick
mode, the torque converter can slip during aggressive driving or heavy loading conditions such as trailer
towing or driving up steep grades. In the non AutoStick
mode, internal controller logic prevents the transmission
from overheating by managing the shift and EMCC schedule. In the AutoStick
mode, when the transmission or
engine temperature approaches an overheat condition, the manual shift overheat DTC sets and the AutoStick
mode is temporarily suspended until the temperature returns to normal.
Diagnostic Test
1.MANUAL SHIFT OVERHEAT
This is an informational DTC only.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.

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
