P2756
Torque Converter Clutch Pressure Control Solenoid
Transmission
Generic OBD-II
Medium
What it means
P2756 means the transmission control module detected a problem with the torque converter clutch (TCC) pressure control solenoid — the valve that applies and releases the converter lock-up clutch. A fault can cause shudder, slipping, poor fuel economy, and even stalling when you slow to a stop if the clutch won't release. It's usually the solenoid, fluid, or wiring.
Medium
Can I keep driving? Drivable but may shudder, slip, or stall when slowing to a stop if the converter clutch won't release; fuel economy suffers.

How to diagnose & fix
Work through it in order
- Read freeze-frame; note whether it sets at lock-up or when coming to a stop.
- Check transmission fluid level and condition first.
- Inspect the solenoid connector and wiring.
- Measure the solenoid resistance against spec.
- Replace the TCC solenoid or service the valve body; clear and road-test.
FAQ
Quick answers
Is it safe to drive with P2756?+
Short-term yes, but if the converter clutch won't release the engine can stall as you slow to a stop. Expect shudder and worse fuel economy — have it fixed soon.
Can I just clear P2756?+
It returns until the solenoid, fluid, or valve-body issue is repaired. Clearing it won't stop the shudder or stalling.
