Most Reported On
P2758 is an OBD-II diagnostic trouble code meaning “Torque Converter Clutch Pressure Control Solenoid Control Circuit Stuck On.” This code indicates the transmission control module detected that the torque converter clutch (TCC) pressure control solenoid appears stuck in the on/applied state. This solenoid manages the hydraulic pressure that locks and unlocks the torque converter clutch for efficiency. If it stays applied when it should release, the clutch will not disengage on demand, which can cause the engine to stall, shudder, or the transmission to overheat. This should be inspected promptly to avoid transmission damage. This code is most commonly reported on 2005-2012 Toyota Avalon, with repair costs ranging from $150 to $5,000.
