Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical

Generic OBD-II
Medium
What it means
P2759 is an electrical fault in the torque converter clutch (TCC) pressure control solenoid circuit. This solenoid controls converter lockup, which links the engine to the transmission for efficiency at cruising speed. An electrical fault can prevent lockup or cause shudder, hurting fuel economy, and may set a failsafe. The engine still starts and runs.
Medium
Can I keep driving? Usually yes, but you may notice a shudder, lost lockup, or slightly higher rpm on the highway. Get it serviced to protect fuel economy and the converter.
Common symptoms
What you'll notice
- Check-engine light on
- No torque-converter lockup — higher rpm at highway speed
- Shudder or slipping feeling under light load
- Reduced fuel economy
Common causes
Most likely first
- Faulty torque converter clutch (TCC) pressure control solenoidLikely
- Open, shorted, or corroded solenoid wiring or connectorCommon
- Poor electrical connection in the transmission harnessCommon
- Dirty transmission fluid affecting the solenoidLess often
- Faulty TCM/PCM (least likely)Less often
How to diagnose & fix
Work through it in order
- Scan for related codes (P2757, P2758, P2760, P2761) and read freeze-frame.
- Check transmission fluid level and condition.
- Inspect the transmission connector and solenoid wiring for damage or corrosion.
- Measure the solenoid's resistance against spec through the harness.
- Replace the TCC solenoid (typically in the valve body) if faulty; verify the module last.
