TCI's Constant Pressure Valve Bodies eliminate one of the most common installation errors made by pros and amateurs alike - Improper TV cable adjustment. The cable is left either unhooked or incorrectly adjusted, the internal clutches and bands slip, causing great internal friction and loss of transmission efficiency.

A TCI Constant Pressure Valve Body allows proper operation while removing slippage and avoiding common transmission destruction. While the TV cable needs to be connected for part-throttle transmission shift operation, these valve bodies allow more freedom as line pressure is fixed so that there is no chance of a low pressure condition resulting in damage to your transmission.
