The Coan Racing COA‑22030‑AL Turbo II “Billet Brake” 2‑Speed Kit is a high-performance valve body upgrade for Turbo II (2-speed) transmissions, crafted entirely from precision billet aluminum and designed around a forward‑pattern shift sequence (P‑R‑N‑2‑1). This fully manual “instant reaction” kit provides reliable trans‑brake functionality in first gear and reverse, allowing racers to stage with exceptional line pressure and launch control. Its lightweight billet body is engineered for durability and rapid hydraulic response, enhancing operational efficiency and consistency in race environments.

Installation-ready, the kit includes a CNC-machined valve body, billet solenoid block, manual valve, separator plate, accumulator spring, modulator plug, and replacement direct clutch springs, everything required to withstand high-RPM launch demands. It’s also compatible with intermediate clutches or Coan’s COA‑22883 Intermediate Clutch Eliminator, allowing custom torque delivery and reduced complexity.

Designed to install within the OEM bolt pattern of the TH400 case, the COA‑22030‑AL provides an efficient drag-racing solution that balances reduced weight, precise hydraulic performance, and keypad-level staging control, perfect for forward-pattern Turbo II drag setups.
