The TCI TH400 full manual valve body is controlled entirely by manual shifting for quicker shift timing and higher line pressures than an automatic shift transmission allows. Higher line pressure helps the clutches resist slipping under high loads. This valve body uses a reverse shift pattern and provides 1st and 2nd gear engine braking, making it a strong choice for bracket cars and off-road competition vehicles where a transbrake is not legal or not desired.
