Trans Brake Kit w/ Clean Neutral - Low Clutch Apply, Reversed Pattern P-R/N-1-2-3-N

TRANS BRAKE KIT W/ CLEAN NEUTRAL (REVERSED PATTERN. LOW CLUTCH APPLY, P-R/N-1-2-3-N)

REQUIRES P08-408/P08-458 SHIFTER (MUST BE USED WITH BILLET ALUMINUM DIRECT DRUM COA-32801)

The Coan Racing COA-32025A Trans‑Brake Kit with Clean Neutral is a premium drag‑race valve body assembly engineered for Turbo Hydramatic 350 transmissions that demand precise control and safety during staging. Built with a reversed shift sequence (P – R/N – 1 – 2 – 3 – N), it incorporates clean-neutral functionality, ensuring that when the shifter returns to neutral after an attempt, the transmission is hydraulically isolated to prevent engagement or runaway, enhancing safety on the line. Designed for low clutch apply pressure, it delivers smooth off-the-line engagement, making it ideal for bracket, index, and other performance racing scenarios. The kit requires use of a P08-408 or P08-458 performance shifter and must be paired with Coan's billet aluminum direct drum (COA-32801) to support the clean-neutral design.

This high-performance kit includes a precision-machined valve body, trans-brake valve and solenoid, hardened separator plate, gaskets, servo spacers, set screws, return springs, and a pipe plug. During installation, all stock check balls are removed, the governor is discarded, and the intermediate servo piston is modified per Coan’s thorough instructions. These components work together to deliver firm, consistent trans-brake activation and clear neutral positioning, ideal for bracket, index, and competition drag racers seeking precise launch control and safety in a race-legal package.
