Intermediate Pressure Plate Support - Billet Aluminum

INTERMEDIATE PRESSURE PLATE SUPPORT, BILLET ALUMINUM

The Coan Racing COA‑22819 Intermediate Pressure Plate Support is a precision-machined billet aluminum component designed to add critical reinforcement to the intermediate pressure plate area in Turbo Hydramatic 400 transmissions. Manufactured in the USA, this support replaces areas of the case that lack built-in strength to cope with high hydraulic line pressures. Notably, it locks in place using the intermediate band anchor and a shouldered bolt through the servo pin bore, anchoring the assembly and preventing pressure plate bowing or warping that commonly leads to early clutch wear.

The COA‑22819 is both lightweight and impactful. Its design ensures the intermediate clutch pack maintains uniform pressure, extending component life during intense drag or bracket racing scenarios. Installation is effortless, fitting stock TH400 cases without modifications, while including necessary hardware for a straightforward assembly.

In high-performance rebuilds or race-focused builds, this intermediate pressure plate support offers a simple yet effective upgrade to uphold clutch integrity and transmission reliability under extreme conditions.
