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)
3.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.
Ignition on, engine not running.
With the Transmission Simulator, turn the Pressure Switch selector switchtoL/R.
With the scan tool, monitor the L/R Pressure Switch State while pressing the Pressure Switch Test button.
Did the Pressure Switch state change from open to closed when the test button was pressed?
Ye s>>
