TCI 13-Vane Billet Rotor Kits

TCI's billet 13-vane rotor pump upgrade kits can be used as a direct replacement on stock or performance-upgraded GM 200R4, 700R4, 4L60, 4L60E, 4L65E, and 4L70E transmissions. Factory 10- and 13-vane pumps can experience line pressure fluctuations at higher rpm. The robust 13-vane billet rotor adds strength while increasing pump fluid volume to maintain consistent, stable pressure. The hardened pump vane rings add an additional level of durability. Machined from 8620 billet steel, TCI 13-vane pump rotors are strong, and the vanes are precision-machined to exacting tolerances. Perform with proper fluid circulation and consistent line pressure, no matter what your level of performance is with TCI 13-vane billet rotors pumping in your transmission. Show Less
