Class Competition Manual w/ Trans Brake, 36 Element Sprag - Reversed Pattern, Chevrolet 6" Extension

The COA‑31121‑0 merges top-tier components into a race-ready Turbo Hydramatic 350 transmission that’s engineered for serious bracket competition. This transmission is centered around a billet aluminum direct drum containing a 36-element sprag, paired with a billet aluminum forward drum and an alloy input shaft, delivering robust one-way clutch performance during hard launches and aggressive gear transitions. It features a lightweight construction throughout, including lite components and an aluminum low-volume pump body and gears, minimizing rotating mass to maximize throttle response and efficiency. The inclusion of a trans‑brake in a reversed shift pattern offers instantaneous, razor-sharp launches from the line, while the Chevrolet-style 6″ extension housing ensures precise tailshaft alignment under extreme load. Built to Coan Racing’s exacting standards and assembled in the USA, the COA‑31121‑0 is purpose-designed for racers who demand elite performance, durability, and control on the track.
