P2764 on Subaru
Torque Converter Clutch Pressure Control Solenoid Control Circuit Low
P2764 on Subaru vehicles indicates torque converter clutch pressure control solenoid control circuit low. Au7o has documented this code across 1 Subaru model — most commonly on Ascent. This code means the powertrain or transmission control module detected a low-voltage condition in the control circuit for the torque converter clutch (TCC) pressure control solenoid. This solenoid regulates the hydraulic pressure that locks and unlocks the torque converter clutch for fuel efficiency. A low circuit fault can prevent proper clutch engagement, causing harsh or erratic shifting, slipping, stalling, or transmission overheating. The cause is most often electrical but can involve the solenoid or fluid condition. Typical repair costs on Subaru range from $1,500 to $8,500, depending on the specific model and root cause.
Common Causes of P2764
- •Faulty TCC pressure control solenoid
- •Damaged or corroded wiring/connectors in the circuit
- •Short to ground in the control circuit
- •Low or contaminated transmission fluid
- •Valve body issues
- •Poor ground or power supply
- •Faulty PCM/TCM
P2764 on Subaru by Model
Subaru Ascent(1 issue)
- CVT Valve Body Failure and Transmission Warning2019-2024
The Ascent's TR730 high-torque CVT develops valve body failures that cause erratic shifting, harsh engagement, and transmission warning lights. The valve body controls hydraulic pressure to the CVT pulleys and chain, and when solenoids or passages within it fail, the transmission cannot maintain proper ratio control. This issue is distinct from the CVT hesitation TSB and represents a hardware failure rather than a calibration issue.

What does P2764 mean on Subaru?▼
P2764 stands for "Torque Converter Clutch Pressure Control Solenoid Control Circuit Low." This code means the powertrain or transmission control module detected a low-voltage condition in the control circuit for the torque converter clutch (TCC) pressure control solenoid. This solenoid regulates the hydraulic pressure that locks and unlocks the torque converter clutch for fuel efficiency. A low circuit fault can prevent proper clutch engagement, causing harsh or erratic shifting, slipping, stalling, or transmission overheating. The cause is most often electrical but can involve the solenoid or fluid condition. On Subaru specifically, this code is documented across 1 model.
