Torque Converter Clutch Pressure Control Solenoid Circuit/Open
The P2761 code indicates an open or malfunction in the electrical circuit of the torque converter clutch (TCC) pressure control solenoid. This solenoid regulates hydraulic pressure to engage and disengage the TCC, which locks the torque converter to improve fuel economy and reduce transmission heat. An open circuit means the solenoid is not receiving power or ground, or the solenoid itself has failed internally. This can prevent the TCC from locking, leading to increased RPM at highway speeds, poor fuel economy, and potential transmission overheating.
01. Most Common Causes
- Faulty torque converter clutch pressure control solenoid
- Open or shorted wiring in the solenoid circuit
- Poor electrical connection at the solenoid or transmission control module (TCM)
- Failed TCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Increased engine RPM at highway speeds (no TCC lockup)
- Poor fuel economy
- Transmission slipping or shuddering during lockup
- Transmission overheating
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the wiring and connector at the transmission for damage, corrosion, or loose pins.
Step 3: Using a multimeter, measure resistance of the TCC solenoid (typically 10-30 ohms). Compare to specs.
Step 4: Check for voltage and ground at the solenoid connector with key on, engine off. Should see battery voltage on one pin.
Step 5: If wiring and solenoid are good, test the TCM output by commanding the solenoid on/off with a scan tool and monitoring voltage.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances. The TCC will not lock, causing higher RPMs, reduced fuel economy, and potential transmission overheating. Short trips to a repair shop are okay.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair. If the solenoid needs replacement, parts are $20-$80 and labor $50-$100. Wiring repairs are usually less.
