Firepunk Full Manual Valve Body (FMVB)

This is full manual control. The transmission will not shift automatically. You control every gear, Overdrive, and TCC lockup.

Every Firepunk FMVB is completely torn down, cleaned, inspected, and rebuilt in-house at our Ohio facility. Each unit is vacuum tested to verify proper sealing and dyno tested to confirm pressure and function before it ships. If a valve body does not meet our specifications, it is corrected before leaving our shop.

The FMVB eliminates common failure points by removing the governor pressure solenoid, transducer, and TV cable. This gives you direct mechanical control of the transmission.

Each unit includes new OD and TCC solenoids with a new wiring harness, a heavy duty 1–2 accumulator spring, and a new filter. All valve bodies are built for firm, quick shifts with improved 3–4 shift performance.

This is not a stock replacement. It is built for full driver control, higher horsepower applications, and aggressive use.
