The Speedmaster PCE634.1010.01 is a billet transbrake valve body designed specifically for the Chrysler 727 Torqueflite automatic transmission. Engineered for full manual operation with a reverse shift pattern, this valve body gives drivers complete control over gear selection, making it an ideal upgrade for drag racing and high-performance driving applications where precise, driver-commanded shifts are essential.
The integrated transbrake function allows the driver to simultaneously apply forward and reverse gears to build maximum torque converter stall at the starting line, then release for explosive launches. The billet construction provides durability and precision over stock valve body components, delivering consistent performance under demanding conditions. Designed to fit the Chrysler 727 Torqueflite transmission platform.
