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 3- and related clutches. The transmission control module (TCM) looks for 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.

The attained gear slip is 100 RPM or greater for 3 seconds or more.

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.

Special Tools

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.
3. Verify that the scan tool parameter matches the Shift Solenoid Valve State and Gear Ratio table for each gear selected.

Important: You must perform the Circuit/System Verification before proceeding with 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 Solenoid Performance Test to test for a stuck open or stuck closed shift solenoid valve inside of the control solenoid (w/body and TCM) valve assembly.

⇒	If a stuck open or stuck closed valve is found, perform the Control Solenoid Valve and Transmission Control Module Assembly Cleaning procedure in an attempt to clean or free up a potential sticking valve of dirt or debris.

3. If the DTC resets after the cleaning procedure perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection.

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

⇒	If the control solenoid (w/body and TCM) valve assembly shift solenoid functions correctly, inspect the lower control valve body assembly for the following:

•	Clutch select solenoid valve and valve body bore for scratches, gouges, scuffing, scoring, and sediment.

•	The valve should move freely in the bore without stopping or binding.

•	Inspect clutch select valve 2 (CSV2) fluid circuits for blockage.

•	Inspect the control solenoid (w/body and TCM) valve assembly filter plate for sediment or debris that could block the apply fluid flow.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
