1 vehicles · 1 makes · $1,500-$8,500 repair
Most Reported On
P2764 is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2019-2024 Subaru Ascent, with repair costs ranging from $1,500 to $8,500.
