The Coan Racing COA‑11147 “Ultimate Big Dog” Super Glide Shorty is a race-caliber, 18‑inch Powerglide transmission engineered for peak performance in compact vehicle installations. Built with a rugged steel hub, this torque-packed assembly features an aerospace-grade, ringless “Super Shaft” that combines durability with reduced mass, ensuring consistent strength during aggressive launches.

This transmission includes Coan’s billet Super Pump equipped with a bolt‑in stator to maintain high hydraulic efficiency in demanding race environments. Power delivery is managed through a "Maximum Duty" straight-cut planetary gearset housed in an aluminum carrier, delivering sharp, precise torque handling. The drivetrain is completed with a billet output shaft and a 10-clutch Super Drum, supported by a roller-bearing output for reduced friction and enhanced service life.

Enhanced by a fabricated deep-aluminum pan for improved fluid capacity and cooling, and installed within a Reid case, the COA‑11147 also incorporates a Pro Tree billet brake valve body with reverse lockout. This setup allows for instant, transbrake-style launches while preventing reverse engagement. Designed as a bolt‑in 18‑inch shorty package, it's a turnkey solution for serious racers seeking compact size without compromising top-tier power and track-ready controls.
