Regardless of whether you have a full race, street/strip or a hot street performance vehicle, you need parts that deliver ultimate performance and reliability. The TCI® GM Transmission Front Pump Assemblies with our new 10-Vane Billet Rotor Kit does exactly that by providing superior performance over not only the factory 10-vane systems 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 center, these pumps simple to install because they are a direct bolt-in replacement for the stock piece and ensure proper fluid circulation and consistent line pressure in any level of performance application. TCI® offers Front Pump Assemblies for Powerglide, TH350/400 and 1988 & Later 700R4/4L60E/4L65E applications.
