Torque Converter Clutch Pressure Control Solenoid Control Circuit High
What it means
P2763 means the PCM saw a high (out-of-range) voltage on the torque converter clutch (TCC) pressure control solenoid circuit. This solenoid modulates how the torque converter locks up, so a fault causes shudder, harsh lock-up, or slipping, and can hurt fuel economy. If the converter stays applied you may feel a lug or stall when stopping. The cause is usually a wiring short or a failed solenoid, sometimes aggravated by low or dirty fluid.
Can I keep driving? Driveable but expect torque-converter shudder, harsh lock-up, or reduced fuel economy; if the converter stays locked you may feel a lug or stall when stopping, so fix it soon.

How to diagnose & fix
Work through it in order
- Check transmission fluid level and condition.
- Scan and watch the TCC solenoid command versus actual lock-up data.
- Inspect the solenoid wiring and connector for a short-to-power or open.
- Measure the solenoid resistance against specification.
- Inspect the valve body; replace the solenoid if faulty, then clear and re-test.
