Code P2758 Description
The diagnostic trouble code P2758 indicates that the Torque Converter Clutch Pressure Control Solenoid Control Circuit is stuck on. The torque converter clutch (TCC) is a critical component in an automatic transmission system that helps improve fuel efficiency and reduce heat buildup. The TCC engages to create a direct mechanical link between the engine and the transmission, reducing slippage and improving overall efficiency.
Common Causes of P2758
- Faulty torque converter clutch pressure control solenoid
- Wiring issues or short circuits in the control circuit
- Low transmission fluid levels or contaminated fluid
- Mechanical issues within the transmission
- Software or programming issues in the transmission control module
Symptoms of P2758
- Harsh or delayed shifting
- Decreased fuel efficiency
- Overheating of transmission fluid
- Illumination of the Check Engine Light
- Transmission slipping or shuddering
How to Fix P2758
- Begin by conducting a thorough inspection of the transmission system to identify any visible damage or leaks.
- Use a scan tool to retrieve the trouble codes and pinpoint the specific cause of the issue.
- Test the torque converter clutch pressure control solenoid to determine if it is functioning correctly.
- Inspect the wiring harness and connectors for any signs of damage or corrosion, repairing or replacing as necessary.
- If the solenoid is faulty, replace it with a new one and ensure proper installation and calibration.
Cost to Fix P2758
The cost of repairing a Torque Converter Clutch Pressure Control Solenoid Control Circuit Stuck On issue can vary depending on the specific cause of the problem and the vehicle's make and model.

Frequently Asked Questions about P2758 Code
What does the OBDII code P2758 mean?
P2758 indicates that the torque converter clutch (TCC) pressure control solenoid control circuit is stuck "on," meaning the solenoid isn't functioning as expected, affecting torque converter operation.
What are common symptoms of code P2758?
Symptoms include poor fuel efficiency, transmission slipping, harsh shifting, engine stalling at low speeds, and the Check Engine Light being illuminated.
What causes the P2758 code to appear?
Common causes include a malfunctioning TCC solenoid, wiring issues such as shorts or opens in the circuit, low or dirty transmission fluid, or internal transmission problems.
Can I drive with a P2758 code?
Driving with a P2758 code is not recommended as it can cause further damage to the transmission and lead to unsafe driving conditions.
How do I diagnose the P2758 code?
Diagnosis involves checking the TCC solenoid, inspecting wiring and connectors for damage, verifying transmission fluid condition, and using a scan tool to monitor TCC operation.
What repairs can fix the P2758 code?
Repairs may include replacing the TCC solenoid, repairing or replacing damaged wiring or connectors, flushing and refilling transmission fluid, or addressing internal transmission issues.
How much does it cost to fix the P2758 code?
Repair costs vary but can range from $150 to $500 for solenoid replacement or wiring repairs. Internal transmission repairs may be more expensive.
Can low transmission fluid cause the P2758 code?
Yes, low or dirty transmission fluid can affect solenoid operation and cause the P2758 code to trigger.
What tools are needed to troubleshoot the P2758 code?
You’ll need an OBDII scanner, a digital multimeter for testing circuits, and possibly a transmission fluid pressure gauge for more advanced diagnostics.
Will clearing the code fix the P2758 issue?
Clearing the code without addressing the underlying problem will not fix the issue, and the code is likely to reappear.
