TCI's new 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.

The 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.
