This TCI Full Manual Valve Body is a competition valve body for the aluminum-case Powerglide with a forward shift pattern. Controlling the valve body through manual means allows quicker shift timing and higher line pressures than an automatic shift transmission, which makes it harder for clutches to slip under high loads. It is an excellent choice for bracket cars, monster trucks and off-road competition vehicles where a transbrake is not legal or not desired.
