2.CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT FOR AN OPEN
Turn the ignition off to the lock position.
Disconnect the PCM C4 harness connector and install Miller tool #8815.
Disconnect the Transmission Solenoid harness connector.
Disconnect the Line Pressure Sensor/Variable Force Solenoid harness
connector (if equipped).
CAUTION: Do not probe the PCM harness connectors. Probing the

form diagnosis.
Ignition on, engine not running.
Using the scan tool under the TIPM Actuators, actuate the Transmis-
sion.
Using a 12-volt test light connected to ground, check the (T16) Trans-
mission Control Output circuits.

P1713-RESTRICTED MANUAL VALVE IN T2 RANGE
For a complete wiring diagramRefer to Section 8W
When Monitored:
Ignition on, engine running with the gear shift selector in a valid forwardgear.
Set Condition:
This DTC sets whenever Transmission control system detects the manual valve is in the T2 range when it
should be in OD. This is mainly an informational DTC.
Possible Causes
RELATED TRANSMISSION DTC’S PRESENT
CUSTOMER DRIVING HABITS
MIS-ADJUSTED SHIFTER CABLE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Diagnostic Test
1.DETERMINING IF RELATED DTC’S ARE PRESENT
With the scan tool, check for other transmission DTC’s
Are there any speed sensor or gear ratio DTCs present?
Ye s>>
Refer to the Transmission category and perform the appropriate symptom.
No>>
Go To 2
2.CHECK THE GEAR SHIFT CABLE FOR PROPER ADJUSTMENT
Check the Gear shift cable adjustment per the Service Information.
Also check the cable for possible binding or improperly routed.
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.
Diagnostic Test
1.PCM AND WIRING
Turn the ignition off to the lock position.
Remove the Ignition Switch Feed fuse from the TIPM.
CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being
startedingear.
WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in
personal injury or death.
Install the Transmission Simulator,Miller tool #8333 and the ElectronicTransmission Adapter kit 8333-1A.
Ignition on, engine not running.
With the Transmission Simulator, set the
Input/Output Speedswitch toONand the rotary switch to the3000/
1250
position.
With the scan tool, monitor the Input and Output Speed Sensor readings.
Does the Input Speed read 3000 RPM and the Output Speed read 1250 RPM, ± 50 RPM?
Ye s>>
Go To 2
No>>
Go To 3
2.(T13) SPEED SENSOR GROUND CIRCUIT OPEN
Turn the ignition off to the lock position.
Disconnect the PCM C4 harness connector.
Disconnect the Input and Output Speed Sensor harness connectors.
CAUTION: Do not probe the PCM harness connectors. Probing the
PCM harness connectors will damage the PCM terminals resulting
in poor terminal to pin connection. Install Miller tool #8815 to per-
form diagnosis.
Measure the resistance of both of the (T13) Speed Sensor Ground cir-
cuits from the appropriate terminal of special tool #8815 to the Input
and Output Speed Sensor harness connectors.
Is the resistance above 5.0 ohms on either circuit?
Ye s>>
Repair the (T13) Speed Sensor Ground circuit for an open.

Perform the following after completion of a diagnostic repair:
Note: After completion of the Transmission Verification Test, the Powertrain Verification Test must be
performed. Refer to the Engine Category.
Reconnect any disconnected components.
With the scan tool, erase all Transmission and Engine DTCs.
Erase DTC P0700 under engine to turn off the MIL off after completion of transmission repairs.
Perform *PRNDL FAULT CLEARING PROCEDURE after completion of repairs for P0706-TRANSMISSION
RANGE SENSOR RATIONALITY.
If the Powertrain Control Module or the Transmission has been repaired or replaced, it is necessary to perform
the scan tool Quick Learn Procedure.
If the Torque converter has been replaced, with the scan tool perform TCC BREAK-IN.
If the Powertrain Control Module or Front Control Module has been replacedyoumustresetthePinionFactor
in the Front Control Module.
With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Tem-
perature is HOT, above 43° C or 110° F.
Check the transmission fluid and adjust if necessary. Refer to the ServiceInformation for the Fluid Fill proce-
dure.
Road test the vehicle. With the scan tool, monitor the engine RPM. Make 15 to20 1-2, 2-3, 3-4 upshifts.
Perform these shifts from a standing start to 45 mph with a constant throttleopeningof20to25degrees.
With speeds below 25 MPH, make 5 to 8 wide open throttle kickdowns to 1st gear. Allow at least 5 seconds
each in 2nd and 3rd gear between each kickdown.
For a specific DTC, drive the vehicle to the Symptom’s When Monitored/WhenSet conditions to verify the DTC
is repaired.
If equipped with AutoStick, upshift and downshift several times using the AutoStickfeature during the road
test.
Note: Use the OBDII task manager to run a Good Trip in each gear, this will confirm the repair and to
ensure that the DTC has not re-matured.
Check for any Diagnostic Trouble Codes (DTCs) during and after the road test.
Did any Diagnostic Trouble Codes set during the road test?
Ye s>>
Repair is not complete. Refer to the Transmission category and perform theappropriate symptom(s).
(Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - DIAGNOSIS AND TESTING)
