Buying advice

When choosing a lock-up solenoid, match the solenoid current rating to your engine’s torque converter specifications, ensure the voltage and mounting are compatible, and consider the operating temperature range of the vehicle. A higher-rated solenoid (2000A+ or 1200A) is ideal for performance or heavy-duty engines, while a lower-rated model (500A-1000A) suits standard passenger cars. Also verify the product’s warranty and supplier reputation for reliable support.
