Code P1775 Description

The P1775 diagnostic trouble code indicates that the solenoid switch valve is stuck in the Torque Converter Clutch (TCC) position in the transmission. The TCC is responsible for locking the torque converter in place to eliminate the slip between the engine and the transmission, improving fuel efficiency and performance. When the solenoid switch valve becomes latched in the TCC position, it can prevent the torque converter from functioning correctly, leading to a variety of issues.
