Control Solenoid Valve and Transmission Control Module Assembly Inspection
WARNING: This page is about a different car, the 2021 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
- Verify the conditions listed below do not exist. Carefully inspect the control solenoid valve assembly connectors and pins (1, 2, 4, 6) for the condition. Repair or replace as necessary.
- Damage
- Bent pins
- Debris
- Broken retaining tab
- Contamination
- Verify there is no metallic debris inside the connectors near the terminal pins. Clean as necessary.
- Verify the control solenoid valve assembly solenoid leads (3) do not have contamination or metallic debris. Clean as necessary.
- Verify the resistance between the leads of each solenoid valve is within the range in the table below, with the solenoid valves at room temperature. If the resistance of any solenoid valve is not within range, replace the Control Valve Body Assembly.
- Inspect the 2 control solenoid valve assembly filter plate retaining tabs (5) for cracks and ensure proper tension when filter plate is attached.
NOTE:
The connector on the TCC pressure control solenoid valve (8) will be either clear/transparent or yellow. The clear/transparent connector will have a color contrast when compared to the connectors on pressure control solenoid valve 2 (11) and pressure control solenoid valve 4 (12).
