P2764

Torque Converter Clutch Pressure Control Solenoid Control Circuit Low

Q: 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.

Q: Can I just clear P2764?

It will return until the solenoid circuit fault is repaired, and driving with it can worsen converter shudder.

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 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.
