TCI TH400 Forward Manual Valve Body 221200

The TCI 221200 is a TH400 full manual valve body with a forward shift pattern. It is built for competition use where the driver controls the valve body manually rather than relying on automatic shift timing.

Manual valve-body control supports quicker shift timing and higher line pressure than a conventional automatic-shift setup. Higher line pressure helps make clutch slip more difficult under heavy load.

This valve body is intended for TH400 performance builds that need direct manual shift control with a forward-pattern layout. Verify that the selected shift pattern matches the driver, shifter, and class rules before ordering.
