TRANS BRAKE KIT W/ CLEAN NEUTRAL (PR/N123N)

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

The Coan Racing COA‑22025 Trans Brake Kit with Clean Neutral (PR/N123N) is a performance-grade hydraulic upgrade engineered for Turbo-Hydramatic 400 transmissions focused on launch precision and safety. Tailored to the reversed shift sequence (PR/N123N), this kit combines trans brake capability with a dedicated clean-neutral setting, allowing racers to stage confidently in a safer neutral position before launching. The valve body assembly includes a trans brake solenoid, high-performance springs, an upgraded accumulator, and brake valve, all pre-installed for dependable line pressure and firm engagement at launch.

Installation requires a compatible shifter (Precision P08‑408 or P08‑458) and billet aluminum direct drum (COA‑22814 or COA‑22815) to ensure accurate gear selection, precise control, and reduced wear under high-load conditions. It’s designed to drop into the stock valve body bolt pattern with minimal modifications, and includes clear instructions for hydraulic calibration. As a result, the COA‑22025 delivers the reliability, responsiveness, and launch control needed for serious bracket, drag, or performance builds, while offering the added safety and convenience of a clean-neutral position between runs.
