CASE VENT

The Coan Racing COA‑12835 Case Vent is a compact yet essential breather component specifically designed for GM Powerglide transmissions. Precision made to fit directly into the transmission case, this vent allows internal air pressure to equalize safely, preventing fluid leaks and maintaining optimal hydraulic balance. Its durable construction ensures longevity under high-temperature and high-pressure conditions commonly encountered in performance and racing environments.

As a subtle but critical maintenance part, the COA‑12835 preserves transmission efficiency and reliability by supporting sealed hydraulic integrity across demanding operating cycles.
