Trans Brake Solenoid GM TH-400

The Trans Brake Solenoid GM TH-400 is a specialized transmission control component designed for high-performance and drag racing applications where precise engine braking and launch control are essential. This solenoid is engineered by Transmission Specialties to meet the demands of racers and automotive enthusiasts who require consistency and repeatability during hard launches, especially in vehicles equipped with the TH-400 three-speed automatic transmission.

This transmission brake solenoid operates by momentarily applying hydraulic pressure to keep the transmission's output shaft stationary while the engine builds RPM or boost at the starting line. This feature allows for load-free acceleration, reducing tire slip and enhancing launch traction. The solenoid is designed for rapid response and durability, capable of withstanding the high-load cycles typical in competitive driving scenarios.

Bracket racers, street/strip hybrid builders, and serious TH-400 enthusiasts will find significant benefits from this solenoid's precision control. Its robust construction is rated for modified engines producing high torque figures, making it an ideal choice for those looking to optimize their vehicle's performance on the strip or street.
