P2757
Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off
Automatic transmission (TCC solenoid)
Generic OBD-II
Medium
What it means
P2757 means the torque converter clutch (TCC) pressure control solenoid isn't performing and appears stuck off, so the converter can't lock up. The car still drives, but engine RPM stays higher at cruising speed, fuel economy drops, and the transmission runs hotter. Typical causes are low or dirty fluid, a failed solenoid, or a wiring/valve-body issue.
Medium
Can I keep driving? Yes — the car drives, but the torque converter won't lock up, so expect higher engine RPM at highway speed and worse fuel economy; repair to avoid transmission heat buildup.
Common symptoms
What you'll notice
- Higher-than-normal engine RPM at steady highway speed
- Reduced fuel economy
- No torque-converter lockup or a slipping feel under light load
- Transmission running hotter than usual
- Check-engine light on
Common causes
Most likely first
- Low or dirty transmission fluidLikely
- Faulty torque converter clutch pressure control solenoid (stuck off)Common
- Open, shorted, or corroded solenoid wiring/connectorCommon
- Valve body or internal hydraulic faultLess often
- Transmission control module fault (least likely)Less often
How to diagnose & fix
Work through it in order
- Check transmission fluid level and condition first.
- Scan for companion codes and confirm the converter isn't locking.
- Inspect the solenoid connector and internal harness for damage or corrosion.
- Back-probe and measure the TCC solenoid resistance against spec.
- Service or replace the solenoid/valve body; consider the module only after checks pass.
FAQ
Quick answers
Is it safe to drive with P2757?+
Yes for normal driving. Stuck-off just means no lockup — higher highway RPM and worse economy. Fix it before long trips so the transmission doesn't run hot.
Can I just clear P2757?+
You can, but a stuck solenoid or wiring fault brings it back. Check the fluid and connector, since those are common triggers.
