The Shiftworks C350-2 is an automatic floor shifter conversion kit specifically designed to bridge the gap between classic vehicle aesthetics and modern transmission technology. This kit is engineered for 1970 Chevrolet Monte Carlo models equipped with TH350 and TH400 transmissions, offering a clean, bolt-in solution. Its primary function is to enable your original factory automatic floor shifter to operate correctly with a modern overdrive transmission, providing a factory-original appearance and feel. The kit includes the necessary components to achieve this conversion, ensuring the shifter functions as if it were originally installed that way from the factory. Shiftworks provides a complete solution to save time and deliver factory-style results for your classic vehicle. The C350-2 kit includes a shift indicator, ensuring all indicators on your shifter console remain functional and accurate. The product is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled Vehicles, and Racing Use Only Vehicles, as it does not affect vehicle emissions.
