Description

SHORTY ALUMINUM PLATE W/BUSHING (FEATURES A SNAP RING TO ELIMINATE SEAL "WALK-OUT"). The Coan Racing COA‑12790 Shorty Aluminum Plate with Bushing is a precision-engineered upgrade designed for GM Powerglide transmissions utilizing the shorty case configuration. A standout feature is the incorporation of a snap ring retention system that eliminates common seal "walk-out" issues, ensuring long-term sealing integrity without the need for expensive rework or seal migration concerns. Crafted to Coan’s high-quality performance standards, the COA‑12790 installs as a direct bolt-in component, simplifying assembly while enhancing durability. Ideal for race or performance-focused Powerglide builds, it provides improved support and leak prevention in a compact, race-ready package.
