P0760-OD SOLENOID CIRCUIT (CONTINUED)
5.
(T60) OD SOLENOID CONTROL CIRCUIT SHORT TO GROUND
Measure the resistance between ground and the (T60) OD Solenoid
Control circuit.
Is the resistance below 5.0 ohms?
Yes
>> Repair the (T60) OD Solenoid Control circuit for a short to
ground.
Perform 42RLE TRANSMISSION VERIFICATION TEST -
VER 1.
No
>> Go To 6
6.
(T60) OD SOLENOID CONTROL CIRCUIT SHORT TO VOLTAGE
Remove the Transmission Control Relay.
NOTE: Check connectors - Clean/repair as necessary.
Connect a jumper wire between the (A104) Fused B+ circuit and the
(T16) Transmission Control Relay Output circuit in the Transmission
Control Relay connector.
Ignition on, engine not running.
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 Special
Tool #8815 to perform diagnosis.
Measure the voltage of the (T60) OD Solenoid Control circuit.
Is the voltage above 0.5 volts?
Yes
>> Repair the (T60) OD Solenoid Control circuit for a short to
voltage.
Perform 42RLE TRANSMISSION VERIFICATION TEST -
VER 1.
No
>> Go To 8

OD SOLENOID/PRESSURE SWITCH ASSEMBLY
If there are no possible causes remaining, view repair.
Repair
Replace the Transmission Solenoid/Pressure Switch Assembly per the Service Information.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1.
8.
POWERTRAIN CONTROL MODULE
Using the schematics as a guide, inspect the wiring and connectors. Repair as necessary. Pay particular attention
to all power and ground circuits.
If there are no possible causes remaining, view repair.
Repair
Replace the Powertrain Control Module per the Service Information. With the scan tool perform QUICK
LEARN.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1.

INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set the DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
Wiggle the wires while checking for shorted and open circuits.
With the scan tool, check the EATX DTC EVENT DATA to help identify the conditions in which the DTC was set.
Were there any problems found?
Yes
>> Repair as necessary.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1.
No
>> Test Complete.

MATICS AND DIAGRAMS)
For a complete wiring diagram Refer to Section 8W.
•
When Monitored:
Initially at ignition on, then every 10 seconds thereafter. The solenoids will also be tested immediately after a
gear ratio error or pressure switch error is detected.
•
Set Condition:
Three consecutive solenoid continuity test failures, or one failure if test is run in response to a gear ratio or
pressure switch error.
Possible Causes
RELATED TRANSMISSION RELAY DTCS PRESENT

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - DIAGNOSIS AND TESTING).
Theory of Operation
Four solenoids are used to control the friction elements (clutches). The continuity of the solenoid circuits is period-
ically tested. Each solenoid is turned on or off depending on its current state. An inductive spike should be detected
by the PCM during this test. If no spike is detected, the circuit is tested again to verify the failure. In addition to the
periodic testing, the solenoid circuits are tested if a gear ratio or pressure switch error occurs. In this case, one
failure will result in the appropriate DTC being set. The MIL will illuminate and the transmission goes into neutral, if
the DTC is set above 35 Km/h (22 MPH), Limp-in mode when vehicle speed is below 35 Km/h (22 MPH).
Diagnostic Test
1.
DETERMINING IF RELATED RELAY DTCS ARE PRESENT
With the scan tool, read Transmission DTCs
Are there any Transmission Control Relay DTCs present also?
Yes
>> Refer to the Transmission category and perform the appropriate diagnostic procedure.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1.
No
>> Go To 2
2.
CHECK TO SEE IF P0765 IS CURRENT
With the scan tool, view DTCs.
Is the status Active for this DTC or is the STARTS SINCE SET counter set to 0?
Yes
>> Go To 3
No
>> Go To 9
