Torque Converter Clutch Pressure Control Solenoid Circuit Intermittent
The P2760 code indicates an intermittent electrical issue in the circuit of the torque converter clutch (TCC) pressure control solenoid. This solenoid regulates hydraulic pressure to the torque converter clutch, allowing it to engage and disengage smoothly. An intermittent fault means the circuit experiences sporadic open, short, or high resistance, often due to damaged wiring, loose connectors, or a failing solenoid. This can cause erratic TCC operation, leading to shuddering, slipping, or harsh shifting.
01. Most Common Causes
- Faulty TCC pressure control solenoid
- Damaged or corroded wiring/connectors in the solenoid circuit
- Intermittent open or short in the circuit
- Low transmission fluid level or contaminated fluid
- Faulty transmission control module (TCM)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Torque converter clutch shudder or vibration during lockup
- Transmission slipping or delayed engagement
- Harsh or erratic shifting
- Decreased fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data to capture conditions when the fault occurred.
Step 2: Inspect transmission fluid level and condition; top off or replace if necessary.
Step 3: Visually check wiring and connectors for damage, corrosion, or loose connections; repair as needed.
Step 4: Test the TCC solenoid resistance and compare to manufacturer specs; replace if out of range.
Step 5: Perform a circuit integrity test (continuity, shorts to ground/power) using a multimeter.
Step 6: If all else is fine, suspect an intermittent TCM issue; reprogram or replace TCM if necessary.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the intermittent TCC operation can cause transmission overheating, increased wear, and potential failure. Short trips to a repair shop are acceptable if the transmission is not slipping severely.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and simple repairs like cleaning connectors or replacing a solenoid. If the TCM needs replacement, costs can exceed $500.
