8HP70 Transmission Upgrade Kit

The Pure Drivetrain Solutions 8HP70 transmission upgrade is engineered to significantly enhance the holding power and overall reliability of your ZF 8HP70 transmission. This comprehensive rebuild process involves replacing OEM parts with custom billet components, enabling the achievement of the highest available clutch counts and maximum power handling capability. Each stage of this upgrade progressively increases clutch and holding capacity through the integration of specialized parts. The core components of this transmission upgrade include a robust billet clutch hub, upgraded clutches and steels throughout the entire transmission, and all new gaskets, seals, and rings for optimal performance. Enhancements extend to the valve body with upgraded O-rings and seals. The cog drives and shaft are specifically modified to ensure better lubrication transfer, while the clutch baskets are heat-treated and hard anodized for increased durability. The upgrade also comes with a brand new pan, filter element, and fresh fluid, along with a laser-etched logo for a distinctive finish. Accompanying this transmission upgrade is a high-stall torque converter, featuring a super alloy billet stator, a performance lockup clutch assembly, and a fully internally TIG-welded construction. Turbine blade sequence modifications and a performance bearing assembly further contribute to its enhanced capabilities. The primary benefit of this high-stall torque converter is its ability to increase RPM stall while foot braking, which is crucial for building more boost and achieving harder launches, particularly when leaving in second gear.
