P2764
Torque Converter Clutch Pressure Control Solenoid Control Circuit Low
Automatic transmission (torque converter)
Generic OBD-II
Medium
What it means
P2764 means the control module sees low voltage (usually a short to ground) in the torque converter clutch (TCC) pressure control solenoid circuit. This solenoid controls lockup of the converter clutch, so a fault often causes shudder, reduced fuel economy, and sometimes stalling when coming to a stop — but the engine still starts and runs.
Medium
Can I keep driving? Drivable, but expect converter shudder, poorer fuel economy, and possible stalling when slowing to a stop. The engine still starts.
Common symptoms
What you'll notice
- Check-engine light on
- Torque converter shudder or slipping feel
- Reduced fuel economy
- Possible stalling when coming to a stop if the converter clutch stays applied
Common causes
Most likely first
- Short to ground in the TCC pressure control solenoid control circuitLikely
- Faulty torque converter clutch pressure control solenoidCommon
- Damaged, corroded, or loose wiring or connectorCommon
- Low or dirty transmission fluid affecting solenoid operationLess often
- Poor ground or a fault in the PCM/TCM driverLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check transmission fluid level and condition.
- Inspect the TCC solenoid wiring and connector for a short to ground, damage, or corrosion.
- Measure the solenoid resistance and check the control circuit voltage against spec.
- Replace the solenoid or repair the wiring as indicated, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2764?+
Short trips are usually okay, but if the converter clutch stays applied the engine can stall when stopping. Have it diagnosed to avoid stalling and converter wear.
Can I just clear P2764?+
It will return until the solenoid circuit fault is repaired, and driving with it can worsen converter shudder.
