Review SHIFTWORKS Hydromatic Shift Lever fits NOVA TURBO 1968-72

The Shiftworks S643 1968-72 Nova Turbo Hydromatic Shifter is a high-performance, manual valve body shifter designed specifically for use with the General Motors 230-250 4-speed Turbo Hydraulic automatic transmissions found in 1968 to 1972 Chevrolet Novas, among other vehicles. This shifter provides a more direct and responsive feel compared to the stock unit, making it an excellent choice for those seeking improved shifting performance.

The S643 shifter features a precision-machined, billet aluminum knob and base, offering both durability and a sleek, modern appearance. The knob is available in various colors and finishes, allowing you to customize the look of your shifter to suit your preferences or your vehicle's interior.

The shifter's internal components are meticulously engineered to ensure smooth and precise shifts. The shifter uses a manual valve body design, which eliminates the need for a vacuum or electric assist, allowing for quicker and more deliberate shifts. The shifter also includes a heavy-duty detent system, which provides positive engagement and reduces the risk of unintended shifts.

The S643 shifter is designed to be a direct replacement for the factory shifter, making installation straightforward and hassle-free. It is compatible with both stock and aftermarket transmission coolers, and can be used with both manual and power steering systems.

In summary, the Shiftworks S643 1968-72 Nova Turbo Hydromatic Shifter is a high-quality, manual valve body shifter that offers improved shifting performance, durability, and customization options for those with 1968 to 1972 Chevrolet Novas equipped with the 230-250 4-speed Turbo Hydraulic automatic transmission.
