Dodge Dakota (ND). Manual — part 1061
P1715-RESTRICTED MANUAL VALVE IN T3 RANGE
For the Transmission circuit diagram (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE -
SCHEMATICS AND DIAGRAMS)
For a complete wiring diagram Refer to Section 8W
•
When Monitored:
Whenever the PRNDL code indicates Temp3.
•
Set Condition:
This DTC sets when conditions for the DTC P1776 are satisfied or 3 unsuccessful attempts to engage 1st gear
while the shifter is in the temp3 zone. This indicates a restricted port at the manual valve because the shifter
is not fully engaged in the drive position.
Possible Causes
RELATED TRANSMISSION DTC’S PRESENT
CUSTOMER DRIVING HABITS
MISADJUSTED SHIFTER
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - DIAGNOSIS AND TESTING).
Diagnostic Test
1.
DETERMINING IF RELATED DTC’S ARE PRESENT
With the scan tool, check for other transmission DTC’s
Are any of the following DTC’s P0731, P0732, P0733, P0734, P1736 or P0715 present?
Yes
>> Refer to the Transmission category and perform the appropriate symptom.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1.
No
>> Go To 2
2.
CHECK SHIFTER ADJUSTMENT
Check Shifter adjustment per the Service Information.
Is the shifter properly adjusted?
Yes
>> Go To 3
No
>> Adjust the Shifter Assembly per the Service Information.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1.

3.
CHECK CUSTOMER DRIVING HABIT
This DTC can be set if the customer rests their hand on the shift lever while they are driving. The transmission can
be put in the T3 position if just enough forward pressure is exerted on the shift lever.
When this occurs, the feed port to the clutch is restricted, the transmission will declare neutral, and this DTC will be
set. The customer should be informed not to rest their hand on the shifter while driving.
This DTC can also be set by simply bumping the shift lever toward neutral while accelerating.
With the scan tool, check the EATX DTC EVENT DATA to help identify the conditions in which the DTC was set.
If there are no possible causes remaining, view repair.
Repair
This DTC can be set by putting too much forward pressure on the shift lever while it is in the OD posi-
tion. Make sure the customer is informed.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1.

SCHEMATICS AND DIAGRAMS)
For a complete wiring diagram Refer to Section 8W.
•
When Monitored:
Continuously with the ignition on, engine running, with the transmission in gear.
•
Set Condition:
If the ratio of the Input RPM to the Output RPM does not match the current gear ratio. This DTC can take up
to five minutes of problem identification before illuminating the MIL
Possible Causes
RELATED DTC’S PRESENT
INPUT SPEED SENSOR OR WIRING
LOW FLUID LEVEL
CRACKEC OR MISINSTALLED PRIMARY OIL FILTER OR SEAL
WORN SOLENOID SWITCH VALVE OR PLUGS
STUCK OR STICKING MAIN REGULATOR VALVE
BURNED UD OR 4C CLUTCH
CUT 4C OR UD PISTON SEAL
BROKEN 4C PISTON CASTING
BROKEN OR MISSING 4C BLEED ORIFICE
BROKEN OR MISSING UD BLEED ORIFICE
CUT 4C OR UD ACCUMULATOR PISTON SEAL
CRACKED 4C OR UD ACCUMULATOR PISTON
EXTRA CHECK BALL IN PASSAGE DOWNSTREAM OF #7 CHECK BALL POCKET
TRANSMISSION SOLENOID/TRS ASSEMBLY
BROKEN WELD - REACTION CARRIER TO REVERSE SUN GEAR
MISSING TEETH ON INPUT CLUTCH HUB TONE WHEEL
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - DIAGNOSIS AND TESTING).
Theory of Operation
The transmission system uses two speed sensors, one to measure input RPM and one to measure output RPM.
These inputs are essential for proper transmission operation. Therefore, the integrity of this data is verified through
the following checks:
1) When in gear, if the gear ratio does not compare to a known gear ratio, the corresponding in-gear trouble code
is set (DTCs P0731–36).
2) An excessive change in input or output speeds indicating signal intermittent which may result in the DTCs P0715
and/or P0720 to set.
3) If the common speed sensor ground circuit is lost, both sensor inputs will read the signal from the input speed
sensor at idle in neutral. Since the input speed sensor reads 60 teeth from the input clutch hub and the output
speed sensor reads 30 teeth from the park gear, the result is an apparent speed ratio of 1:2 and may cause the
DTC P1794 to set when at a stop.

Diagnostic Test
1.
DETERMINING IF RELATED DTC’S ARE PRESENT
With the scan tool, check for other transmission DTC’s
Are any Transmission: solenoid, line pressure, speed sensor, or loss of prime DTC’s present?
Yes
>> Refer to appropriate symptom in the Transmission category. Perform the test for P0944–LOSS OF
PRIME first if it is present.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1.
No
>> Go To 2
2.
CHECK EATX DTC EVENT DATA
With the scan tool, read and record the EATX DTC EVENT DATA.
NOTE: Make sure to record all EATX DTC EVENT DATA stored in the scan tool for future reference in this
test procedure.
Does the EATX DTC EVENT DATA display information for the DTC P1736?
Yes
>> Go To 3
No
>> Go To 6
3.
CHECK RPM IN EATX DTC EVENT DATA
Refer to the EATX DTC EVENT DATA recorded earlier.
Does the Input RPM read zero?
Yes
>> Check the input speed sensor and wiring. Refer to test P0715 and diagnose as if the DTC is current.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1.
No
>> Go To 4
4.
CHECK LINE PRESSURE READING
Refer to the EATX DTC EVENT DATA recorded earlier.
Is the line pressure reading more than 10 psi below the desired line pressure?
Yes
>> Go To 5
No
>> Go To 6
