DTC Descriptor
DTC P0752
- Shift Solenoid (SS) 1 Valve Performance - Stuck On

Circuit/System Description

The shift solenoid 1 and transmission control module (TCM) are part of the control solenoid valve assembly and are not serviced separately. The transmission control module supplies 12 V to shift solenoid 1 on the high side driver 1 circuit. The transmission control module controls the normally closed shift solenoid 1 on the shift solenoid 1 control circuit. The shift solenoid 1 controls the transmission fluid to the 1-3 clutch regulator valve assembly.

Conditions for Running the DTC

* Any transmission shift without engine or engine transition to Off.
* Line pressure is greater than 325 kpa.

Conditions for Setting the DTC

The transmission control module detects shift solenoid valve 1 is commanded OFF and TCM is unable to confirm transition.

Action Taken When the DTC Sets

P0752 is a Type A DTC.

Conditions for Clearing the DIC/DTC

P0752 is a Type A DTC.

Circuit/System Verification

1. Verify that P0966, P0967, P0969, P0970, P0971, P0973, P0974, P0976, P0977, P2720, P2721, P2728, P2729, or P2730 is not set.

• If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.

2. Perform the Transmission Fluid Level and Condition Check Testing and Inspection.
3. Perform the Line Pressure Check Line Pressure Check.
4. Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection Control Solenoid Valve and Transmission Control Module Assembly Inspection.
5. Perform the Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test.

• If the shift solenoid 1 is found to be leaking or stuck OFF, replace the Q8 control solenoid valve assembly.

• If the Q8 control solenoid valve assembly tests normal, inspect the valve body and hydraulic circuits for a leak or a stuck valve. Refer to Control Valve Body Diagnostic Inspection Control Valve Body Diagnostic Inspection.
