Description

The Hughes Performance HUP-34-1HD is a heavy-duty automatic transmission built for TH400 applications, suitable for both street and strip use. Key specifications include a three-gear setup with a 2.48:1 first gear ratio, and it is advertised to handle up to 750 horsepower. The 34-1HD is designed with a heavy-duty drum and sprag for enhanced strength and reliability. This transmission is specifically noted for its suitability for heavy-duty truck/SUV 2WD applications from 1967-1990 and is designed for towing and RV vehicles. It is not equipped with a torque converter, which will need to be purchased separately. Further compatibility details may be available directly from Hughes Performance.
