The shift solenoid (SS) valve 1 is part of the lower control valve body. The SS valve 1 is a normally closed (NC) solenoid valve and controls fluid to the clutch select valve 2 and related clutches. The transmission control module (TCM) looks for a good shifts from first gear engine braking, to first gear freewheel, to second gear and then if third gear indicates neutral, and the TFP Sw 5 does not change states, the TCM sets the DTC.

Commanded gear has achieved first lock, first free wheel or second gear and current commanded gear equals third.

The transmission case slip speed is 100 RPM or greater for 5 seconds.

DTC P0752 is a Type A DTC.

DTC P0752 is a Type A DTC.

When attempting to set transmission performance DTCs, observe the Freeze Frame and Failure Records to assist in duplicating the failure conditions. Ensure the transmission fluid level is correct and there are no leaks.

DT-47825 Control Solenoid Test Plate

1. Perform the Transmission Fluid Check.
2. Operate the vehicle in drive from a complete stop, with the calculated throttle position greater than 15 percent to obtain 72 km/h (45 mph) 2 times.

⇒	If the DTC resets, go to Circuit/System Testing.

1. Perform the Line Pressure Check.

⇒	If the pressure is out of specification correct that concern first.

2. Perform the Control Solenoid Valve and Transmission Control Module Assembly Cleaning and retest the DTC as outlined in the Circuit/System Verification steps.

⇒	If the DTC resets, continue on with testing.

3. Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection.

⇒	If a concern is found, repair or replace the control solenoid (w/body and TCM) valve assembly.

4. Perform the Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test.

⇒	If the shift solenoid 1 is found to be leaking or stuck ON, replace the control solenoid (w/body and TCM) valve assembly.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
