TH400 Trans Brake Solenoid

The TH400 Trans Brake Solenoid from COAN is purpose-built for serious drag racers and high-performance street car builders who demand absolute control at the starting line. This electromechanical solenoid functions as the electronic gatekeeper for trans brake activation, engaging and disengaging hydraulic pressure with precision timing to hold the vehicle stationary against engine torque during launch. Whether you're building a competition bracket racer, a grudge car, or a street machine with launch control ambitions, this solenoid is an essential component for repeatable, controlled launches that maximize traction and minimize tire spin.

Engineered specifically for the TH400 transmission platform, the COAN trans brake solenoid operates by modulating hydraulic flow to the trans brake circuit, creating the holding pressure necessary to keep the transmission locked in gear while the engine builds boost or RPM at standstill. The solenoid's robust construction and electrical architecture are designed to withstand repeated activation cycles—critical in racing environments where consistency and reliability directly impact lap times and competition results. By integrating this solenoid into your trans brake setup, you gain millisecond-level engagement precision, allowing your launch control system or manual switch to command exactly when the transmission releases.

This solenoid is ideal for those looking to enhance their vehicle's launch capabilities, providing a significant advantage in drag racing scenarios. Its compatibility with the TH400 transmission ensures that it meets the specific needs of high-performance applications. With the COAN trans brake solenoid, racers can expect harder launches with less wheelspin and more predictable acceleration off the line.
