TCI Auto 321000 TH350 Full Manual Valve Body Forward Shift Pattern

The TCI Auto 321000 is a competition-grade full manual valve body designed specifically for TH350 transmissions with a forward shift pattern. This valve body eliminates all automatic shifting functions, giving drivers complete manual control over gear selection for maximum performance and consistency in racing applications.

Key Features:

• Full manual operation for precise shift timing control
• Forward shift pattern (1-2-3) configuration
• 2nd gear engine braking capability for improved control
• Higher line pressure capacity compared to automatic shift valve bodies
• Enhanced clutch holding power under high-load conditions
• Quicker shift response and elapsed times

Performance Benefits:

By removing automatic shift control mechanisms, this valve body allows for significantly higher line pressures that reduce clutch slippage during aggressive launches and gear changes. The manual control enables drivers to execute shifts at optimal RPM points for their specific application, resulting in more consistent elapsed times and improved performance.

Applications:

Ideal for bracket racing cars, monster trucks, off-road competition vehicles, and any high-performance application where a transbrake is not used or not permitted. This valve body is designed for dedicated racing transmissions and is not intended for street use, as it requires manual gear selection for all forward gears including starting from a stop.
