TCI 321000 TH350 Manual Valve Body for Drag and Circle Track Racing

The TCI 321000 TH350 Manual Valve Body is designed for high-performance drag racing and circle track applications that require precise, consistent transmission control. Built for the Chevrolet TH350 automatic transmission, this manual valve body converts operation to a forward-pattern manual shift configuration, giving the driver direct control over gear changes during competition use.
The forward-pattern design helps support predictable shifting and race-focused transmission operation. It is intended for applications where quick, deliberate gear selection is preferred over automatic shifting. The TCI 321000 is a practical choice for performance vehicles using a TH350 transmission in demanding racing environments, including drag cars, circle track cars, and other custom-built competition vehicles.
This valve body kit is engineered for installation into compatible TH350 transmissions and should be matched with the transmission build, shift linkage, and overall race setup. Professional installation and appropriate transmission calibration are recommended to help ensure proper operation and reliable performance. Verify compatibility with your specific TH350 transmission and vehicle configuration before installation.
