TCI® Valve Bodies

Constant Pressure

  • Eliminates chance of transmission failure
  • Fixed line pressure with no chance of low line pressure condition
  • Improved shift characteristics
  • TV cable used only to set shifting speeds
  • Easy installation

Frequently racers and street performance enthusiasts incorrectly install their transmission with the critical throttle valve (TV) cable used to set internal line pressure and part throttle shifting either left disconnected or improperly adjusted. The result can be total transmission melt down.

TCI® recognizes the need for a product that eliminates the chance of transmission failure and produced the Constant Pressure Valve Body™. While the TV cable still needs connection for proper transmission shifting speeds, the TCI® Constant Pressure Valve Body™ provides more freedom when setting part throttle shift points. Line pressure is fixed with no chance of encountering a low line pressure condition, and the shift characteristics are greatly improved. Kits can be installed by anyone with basic mechanical experience.
