TCI 421100 - TCI Streetfighter Valve Bodies

Streetfighter Series - Manual/Automatic

The transmission valve body is the brain of the transmission. Often it is called the control valve. The valve body, like the transmission, has been changed and updated through the years. We select and use only the valve body that will provide you with the best performance and service. All TCI valve bodies are 100% quality checked for proper function and, where applicable, proper operating pressures on a dedicated valve body test machine.

Our manual/automatic valve body is designed for the street and strip performance car owner. It is the same valve body used in our Streetfighter transmission series.
