Is the Gear shift cable properly adjusted and not binding or improperly routed?
Ye s>>
Go To 3
No>>
Adjust the Shifter Assembly per the Service Information.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
3.CHECK CUSTOMER DRIVING HABIT
This DTC can be set if the customer does not move the shift lever completely into the OD position (in between
gears) causing the manual valve to be in the T2 position.
When this occurs, the feed port to the clutch is restricted, the transmission will declare neutral, and this DTC will
set.
This DTC can also be set by simply bumping the shift lever toward neutral while accelerating.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
If there are no possible causes remaining, view repair.
Repair
This DTC can be set by the shift lever inthe wrong position or not completelyin the OD position. Make
sure the customer is properly informed.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

P1794-SPEED SENSOR GROUND ERROR
For a complete wiring diagramRefer to Section 8W.

When Monitored:
Every 7msec after a controller reset with transmission in neutral.
Set Condition:
After a PCM reset in neutral and Input and Output sensor ratio equals 2.50 to1.0 ± 50.0 RPM.
Possible Causes
SPEED SENSOR GROUND CIRCUIT OPEN
POWERTRAIN CONTROL MODULE
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The input and output speed sensors use a common ground circuit. The loss of this common ground results in the
input signal being sensed for both. After a reset in neutral, and after observing a specific ratio, the Speed Check
Fault Counter will increment. Because the speed sensors and the thermistor share the same ground circuit, this
DTC may indicate a loss of the common speed sensor ground. In some cases thisfault will cause a Gear Ratio
Error DTC to be 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
4 - UNDERDRIVE CLUTCH 9 - OUTPUT SHAFT 14 - OIL PUMP
5 - OVERDRIVE CLUTCH 10 - SNAP RING

TORQUE CONVERTER LEAKAGE
Possible sources of torque converter leakage are:
Torque converter weld leaks at the outside diam-
eter weld (1).
Torque converter hub weld (2).
STANDARD PROCEDURE - ALUMINUM THREAD REPAIR
DamagedorwornthreadsinthealuminumtransmissioncaseandvalvebodycanberepairedbytheuseofHeli-
Coils
, or equivalent. This repair consists of drilling out the worn-out damagedthreads. Then tap the hole with a
special Heli-Coil
tap, or equivalent, and installing a Heli-Coilinsert, or equivalent, into the hole. This brings the
hole back to its original thread size.
