3-4 W.O.T. Upshift Kit

3-4 W.O.T. UPSHIFT KIT

Designed to optimize the throttle valve response in Turbo Hydramatic 700R4 transmissions, the COA‑92848 3‑4 W.O.T. (wide-open throttle) upshift kit enhances the precision and consistency of the shift that occurs under full-throttle acceleration. Incorporating a precision plunger and sleeve assembly specially engineered for this application, the kit ensures smoother and more reliable line pressure modulation when transitioning from third to fourth gear. By stabilizing the pressure curve during high-load shifts, it helps eliminate harshness, reduce clutches slippage, and support quicker power delivery through the shift. Ideal for performance-focused street vehicles and mild competition setups, this kit delivers purposeful refinement to your transmission’s hydraulic behavior, building on Coan Racing’s reputation for exacting, race-inspired components.
