External Dump Kit - Line To Lube

EXTERNAL CONVERTER DUMP KIT FOR "LINE TO LUBE" COOLER FLOW, ADJUSTABLE CONVERTER PRESSURE VALVE, MOUNTS IN PLACE OF GOVERNOR COVER

The Coan Racing COA‑22061A External Dump Kit, Line‑to‑Lube is a robust hydraulic solution designed specifically for Turbo-Hydramatic 400 transmissions that utilize the OEM line-to-lube cooler flow setup. This billet aluminum assembly replaces the governor cover and incorporates an adjustable converter pressure valve, allowing excess pressure to be dumped directly into the cooler circuit, effectively preventing over-pressurization during high-stall launches or prolonged staging. By controlling converter charge pressure while preserving normal cooler flow, the kit offers both safety and flexibility under racing conditions.

The COA‑22061A is engineered for durability and ease of use, featuring a clean, bolt-in installation and compatible controls without interfering with engine operation or fluid pathways. It's a vital upgrade for drag racers and performance builders seeking to safeguard transmission seals and fluid integrity during extreme launch pressure without compromising cooler efficiency.
