Regardless of whether you have a full race, street/strip or simply hot street performance vehicle, you need parts that deliver ultimate performance and reliability. The TCI® GM700R4/4L60E/4L65E Transmission Front Pump Assembly with our NEW 10-Vane Billet Rotor Kit does exactly that by providing superior performance over not only the factory 10-vanesystems but the 13-vane aftermarket kits as well. Machined from 8620 billet steel rather than OE powdered metal material, a substantial amount of strength is added, so the rotor kit installed in this pump makes it the best transmission pump you can purchase for your late model GM transmission. Custom designed and tested at the TCI® R & D lab, this pump is simple to install because it is a direct bolt-in replacement for the stock piece and ensures proper fluid circulation and consistent line pressure in any level of performance application. As with all TCI® products, they are inspected for the utmost in high-quality and service-free operation. TCI® offers five different application specific parts to provide perfect fitment to any 700R4/4L60E/4L65E 1982 – current transmission.
