BILLET ALUMINUM INSTANT REACTION TRANS BRAKE KIT W/ CLEAN NEUTRAL AND LOW BAND APPLY (PR/N123N)

REQUIRES P08-408/P08-458 SHIFTER (MUST BE USED WITH BILLET ALUMINUM DIRECT DRUM COA-22814/COA-22815)

The Coan Racing COA‑22027‑AL Billet Aluminum Instant Reaction Trans Brake Kit with Clean Neutral and Low-Band Apply (PR/N123N) is a highly engineered hydraulic solution for Turbo-Hydramatic 400 transmissions, built to meet the demands of serious drag racing. Constructed from precision-machined billet aluminum and designed to fit the reversed shift pattern (PR/N123N), this kit offers instant trans brake activation in first gear, an added low-band apply for smoother launches, and a "clean neutral" safety position for secure shutdown between runs.

Installation of the COA‑22027‑AL requires additional hardware: a Precision P08‑408 or P08‑458 shifter and Coan’s billet aluminum direct drum (COA‑22814 or COA‑22815) to ensure accurate shift positioning and hydraulic compatibility. Supplied as a complete unit, the kit includes a manual selector valve, solenoid block, brake valve and springs, accumulator spring, and O-ring modulator plug, delivering firm, consistent line pressure and rapid brake reaction in high-RPM, high-load scenarios.

By integrating clean-neutral safety with low-band assist and utilizing durable billet aluminum construction, the COA‑22027‑AL offers drag racers a compact, reliable, and responsive trans brake system that prevents inadvertent reverse engagement, enhances launch control, and withstands the extremes of competition. It fits within the stock valve body bolt pattern for a clean installation, making it a turnkey upgrade for serious performance builds.
