EXTERNAL CONVERTER DUMP KIT FOR CONVENTIONAL COOLER FLOW, MOUNTS IN PLACE OF GOVERNOR COVER

The Coan Racing COA‑22061 External Dump Kit (Standard Cooler Flow) is an advanced hydraulic accessory designed specifically for Turbo‑Hydramatic 400 transmissions. Installed in place of the governor cover, this assembly redirects excess converter charge pressure to the transmission cooler under high-load conditions, effectively preventing internal over-pressurization and protecting seals.

The COA‑22061 helps maintain optimal fluid integrity and reduce heat buildup while retaining normal cooler flow during vehicle operation. Ideal for bracket racers or high-stall launch setups, this kit delivers a simple, racing-proven method to safeguard transmission longevity and performance under extreme conditions.
