The Coan Racing COA‑22027A‑AL Billet Aluminum Instant Reaction Trans Brake Kit is a high-performance valve body assembly meticulously crafted from billet aluminum to deliver elite-level drag racing functionality in TH400 transmissions. Featuring a reversed shift pattern (PR/N123N) with an integrated clean-neutral position, this kit empowers racers to stage confidently while minimizing accidental gear engagement between runs. Designed for versatility, the trans brake can be engaged in either first or second gear, offering strategic flexibility for tailored launch setups. The instant-reaction design employs race-grade springs, a precision solenoid block, and an optimized accumulator to maintain robust line pressure for lightning-fast, repeatable braking performance.

Installation requires pairing with Coan’s billet aluminum direct drum (COA‑22814 or COA‑22815) and a compatible Performance Precision P08‑408 or P08‑458 shifter to ensure accurate gear selection and full access to clean-neutral and dual-gear trans brake functions. The kit bolts directly onto the factory TH400 valve body pattern without case modifications, providing a turnkey solution that combines lightweight durability, hydraulic finesse, and drag-strip-ready performance. For racers seeking precise staging, enhanced low-speed control, and versatile trans brake engagement, the COA‑22027A‑AL represents an all-in-one, competition-grade package built to excel at the starting line.
