    This Performance Valve Body Reprogramming Kit with Manual Control allows a C4 automatic valve body to perform like a stick shift/manual shift (meaning no automatic shifts). The transmission will be in the gear you select and changes to any gear you choose when you move the selector. This kit allows the driver full command.

    • Has option to be set up initially or converted back to automatic operation/shifting with minimal changes if desired
    • Raises overall line pressure
    • Firm shift performance
