P2769 Fault Code

Torque Converter Clutch Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2769 fault code indicates a problem with the Torque Converter Clutch (TCC) circuit being low. This typically refers to an insufficient voltage signal from the TCC solenoid. The TCC is crucial for vehicle performance as it helps in locking the torque converter to improve fuel efficiency and reduce engine load.

What are the symptoms of the P2769 code?

Common symptoms associated with the P2769 fault code may include:

• Slipping or shuddering during acceleration.
• Decreased fuel efficiency.
• Overheating transmission.
• Unresponsive torque converter or delayed gear changes.

What causes the P2769 code?

Several factors can contribute to this fault code, including:

• Faulty TCC solenoid or harness connections.
• Low transmission fluid levels or contaminated fluid.
• Wiring issues, such as shorts or open circuits in the circuit.
• Problems with the engine control module (ECM) that oversees TCC operation.

How to fix P2769?

To resolve the P2769 code, consider the following steps:

• Inspect the TCC solenoid and wiring for damage or disconnections.
• Test the electrical connections and repair any faulty wiring.
• Check and replace the transmission fluid if it's low or contaminated.
• If necessary, replace the TCC solenoid or address ECM issues if further diagnostics indicate a failure.
