The TCI 221100 is a TH400 full manual valve body with reverse shift pattern operation. It is built for competition vehicles where the driver controls gear changes manually rather than relying on automatic shift behavior.

Manual valve body control supports quicker shift timing and allows higher line pressure than possible with an automatic-shift transmission. Higher line pressure helps reduce clutch slip under high loads, which is useful in bracket cars, monster trucks, and off-road competition builds.

The reverse shift pattern is the defining detail of this SKU. It is intended for competition use where a transbrake is not legal or not desired, and where the driver wants firm, direct manual control over the TH400 shift sequence.

The TCI 221200 is a TH400 full manual valve body with a forward shift pattern. It is built for racing applications where the driver controls gear changes manually through the valve body instead of relying on automatic shift operation.

Manual control supports quicker shift timing and allows higher line pressure than automatic-shift operation can normally provide. Higher line pressure helps make it harder for clutches to slip under high loads, which is valuable in bracket cars, monster trucks, and off-road competition vehicles.

The forward shift pattern is the key differentiator for this SKU compared with reverse-pattern TH400 valve bodies. It is a strong choice where a transbrake is either not legal or not desired, but the vehicle still needs firm manual shift control.

The TCI 221201 is a TH400 full manual valve body with a reverse shift pattern and 1st and 2nd gear braking. It is built for racing applications where the driver controls the valve body manually rather than relying on automatic shift operation.

Manual valve body control allows quicker shift timing and higher line pressure than an automatic-shift transmission can normally provide. Higher line pressure helps make it more difficult for clutches to slip under high loads, supporting bracket cars, monster trucks, and off-road competition vehicles where a transbrake is not legal or not desired.

The reverse shift pattern and 1st and 2nd gear braking are the key differentiators for this SKU. Confirm TH400 compatibility and shift pattern preference before installation, especially in competition vehicles where driver routine and class rules matter.
