2006 DODGE RAM SRT-10 wiring

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.
Check the engine and transmission cooling system for proper operation.
Check the Radiator Cooling Fan operation.
Check the Transmission Cooling operation.
Check the Transmission Fluid Level per the Service Information to verify that it is not overfilled.
NOTE: Aggressive driving or driving in low for extended periods of time will set this DTC.
If there are no possible causes remaining, view repair.
Repair
If the Transmission Fluid is low, repair any Transmission Fluid leak as necessary and adjust the Trans-
mission Fluid Level per the Service Information. Refer to Service Information for the related symptoms
and repair as necessary.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

STANDARD PROCEDURE
PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE - 42RLE
For a complete wiring diagramRefer to Section 8W.
1.
Perform the following steps prior to any diagnostic procedure:
Many transmission symptoms can be caused by a low fluid level. If the fluid level is low, locate and repair any
leaks and fill the transmission to the proper fluid level. Refer to the Service Information for the proper repair
and fluid fill procedures.
Testing should only be performed with the battery fully charged to avoid false diagnosis.
With the scan tool, read Engine (PCM) DTCs. If Engine DTCs are present, refer to the Driveability Category
and perform to the appropriate diagnostic procedure(s) before proceeding.
With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information.
Diagnose any Pending DTC as a matured DTC.
With the scan tool, read DTC EVENT DATA.Use this data to identify the conditions in which the DTC was set.
Note: Performing a Battery Disconnect will clear all DTC EVENT DATA and reset all learned Transmis-
sion values to the controllers default values, which may temporarily result in erratic shift schedules.
With the scan tool, perform the Shift Lever Position Test. If the test does not pass, refer to the diagnostic
procedure for P0706-Check Shifter Signal.
For Gear Ratio Error DTCs, use the scan tool to read and record the Clutch Volume Index (CVI) information.
Use the wiring diagram as a guide, inspect the wiring and connectors related to this circuit and repair as nec-
essary.
Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, driving
under specific conditions, and after controller diagnostic monitors haverun.
Refer to applicable Technical Service Bulletins (TSBs) for controller software update information. Some condi-
tions can be corrected by upgrading the Engine (PCM) or Transmission (TCM)controller software.
Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply.
Were there any repairs made that fixed the vehicle?

7. Remove any steering column (1) trim necessary to
access the gearshift cable (2) and BTSI mecha-
nism.
8. Disconnect the BTSI wiring connector (5).
9. Disconnect cable at lower column bracket and shift
lever pin and pull the cable through the dash panel
opening into the vehicle.
10. Remove gearshift cable (2) from vehicle.
INSTALLATION
1. Route the transmission end of the gearshift cable
(1) through the opening in the dash panel.
2. Seat the cable grommet (2) into the dash panel
opening.
3. Snap the cable into the steering column (1) bracket
so the retaining ears are engaged and snap the
cable eyelet onto the shift lever ball stud.
4. Raise the vehicle.
5. Place the transmission manual shift lever in the
“PARK” detent (rearmost) position and rotate prop
shaft to ensure transmission is in PARK.
6. Route the gearshift cable through the transmission
mounting bracket and secure the cable by snap-
ping the cable retaining ears into the transmission
bracket and snapping the cable eyelet on the man-
ual shift lever ball stud.
7. Lower vehicle.
8. Lock the shift cable adjustment by pressing the
cable adjuster lock tab (3) downward until it snaps
into place.
9. Check for proper operation of the transmission range sensor.
10. Adjust the gearshift cable (Refer to 21 - TRANSMISSION/AUTOMATIC/GEAR SHIFT CABLE - ADJUST-
MENTS) and BTSI mechanism (Refer to 21 - TRANSMISSION/AUTOMATIC/BRAKE TRANSMISSION SHIFT
INTERLOCK SYSTEM - ADJUSTMENTS) as necessary.

SENSOR-INPUT SPEED
DESCRIPTION
The Input (1) and Output (2) Speed Sensors are two-
wire magnetic pickup devices that generate AC signals
as rotation occurs. They are mounted in the left side
of the transmission case and are considered primary
inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of the input clutch
hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The TCM interprets this information
as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, thoughitscoilisexcitedbyrotationofthe
rear planetary carrier lugs. The TCM interprets this information as outputshaftrpm.
The TCM compares the input and output speed signals to determine the following:
Transmission gear ratio
Speed ratio error detection
CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the following:
Torque converter clutch slippage
Torque converter element speed ratio
REMOVAL
1. Raise vehicle.
2. Place a suitable fluid catch pan under the transmis-
sion.
3. Remove the wiring connector from the input speed
sensor.
NOTE: The speed sensor bolt has a sealing patch
applied from the factory. Be sure to reuse the
same bolt.
4. Remove the bolt holding the input speed sensor to
the transmission case.
5. Remove the input speed sensor from the transmis-
sion case.
