PG Transbrake Solenoid - Closed Style

The PG Transbrake Solenoid – Closed Style from FTI Performance is a specialized transmission control component designed for Powerglide automatic transmissions in high-performance drag racing and street strip applications. This solenoid functions as the electronic command center for transbrake engagement, allowing racers to hold the transmission's output shaft under load while building engine boost or RPM at the starting line. Built for drivers who demand precision launch control and repeatable performance, this closed-style solenoid integrates seamlessly into existing Powerglide systems.

The closed-style design protects internal solenoid components from contamination and moisture, ensuring reliable operation in harsh racing environments and wet conditions. FTI Performance engineered this unit with robust electrical contacts and a sealed housing to withstand repeated actuation cycles at launch without degradation. The solenoid's response time directly impacts launch consistency—precise electronic timing prevents wheel spin and maximizes traction off the line. Weighing 2.27 pounds with compact dimensions of 6.55 x 6.3 x 6.8 inches, it mounts cleanly within the transmission case with minimal installation footprint.

This component is essential for bracket racers, circle track competitors, and street strip enthusiasts running Powerglide transmissions in manual-shift or transbrake configurations. Installation requires integration with a dedicated transbrake controller or transmission control module that sends the activation signal at launch. Proper wiring and adjustment of solenoid timing relative to engine RPM and throttle input ensure optimal bite and consistency. The PG Transbrake Solenoid – Closed Style delivers the reliability and precision that serious racers expect when investing in transmission control systems for competition.
