Description

Coan Racing’s COA‑33420 – TH350 Fluid Overflow Tank, Mounted on Extension Housing, is a precision-engineered accessory designed to improve transmission fluid management and reliability under extreme operating conditions. Crafted specifically for Turbo Hydramatic 350 applications, this overflow tank neatly mounts to the extension housing, providing a secure and compact reservoir that captures excess fluid expelled under extreme pressure or heat. This helps prevent messy fluid discharge, reduce overheating, and maintain optimal fluid levels without having to constantly monitor or refill the transmission. Constructed from durable materials and machined to exact Coan Racing standards, the tank integrates seamlessly with existing racing transmission setups. Its thoughtful placement on the extension housing saves space and keeps fluid containment cleanly contained away from hot engine components, making it an ideal upgrade for clear-sighted racers serious about performance and maintenance.
