P/G Dual Ring Servo Kit

The P/G Dual Ring Servo Kit by TCI is designed for builders and mechanics who are upgrading automatic transmissions, especially in performance builds or restoration projects. This kit addresses a vital component in transmission control systems—the servo mechanism that modulates band apply pressure based on throttle input and load conditions. It is ideal for those looking to enhance shift quality or rebuild transmissions from the ground up.

This dual-ring servo assembly is engineered to provide consistent engagement geometry, which is essential for reliable power transfer and smoother gear transitions. The innovative dual-ring design optimizes the effective piston area and spring preload balance, resulting in improved modulation and more linear band pressure curves. This design minimizes harsh engagements during acceleration and reduces converter lockup lag, enhancing drivability in both stock and modified powertrains.

Technicians and enthusiasts working on vintage muscle cars, street rods, or modern automatic transmissions will find this servo kit beneficial. Its precision-machined components and tight tolerances ensure repeatable performance across multiple shifts. While the compact size allows for installation in many standard transmission housings, users should verify compatibility with their specific applications.
