2000-2002 Dodge Ram 2500/3500 47RE Firepunk Automatic Valve Body | 400HP–1000+HP Options

Firepunk 47RE Performance Valve Body

If your 47RE is shifting soft, hunting gears, or dropping into limp mode, the valve body is usually the problem. This is where shift control and reliability come from.

Every Firepunk 47RE valve body is completely torn down, cleaned, inspected, and rebuilt in-house at our Ohio facility. Each unit is vacuum tested, and dyno tested to confirm pressure and shift function before it ships. If a valve body does not meet our specifications during testing, it is repaired to factory specifications and re-tested before leaving our shop.

We replace the common failure points up front. Every unit includes a new upgraded governor pressure solenoid and transducer, along with new OD and TCC solenoids and a new internal wiring harness. These are the parts that typically cause erratic shifting and limp mode issues.

We include a heavy duty 1-2 accumulator spring to improve shift firmness and consistency. Each valve body also comes with a new filter, plus the correct rooster comb and park rod for your specific year so everything lines up during install.

All Firepunk valve bodies are built with 2nd gear lockup capability. That gives you better control under load, stronger performance, and helps keep heat in check.

This is not a stock replacement. It’s a valve body built to handle power, towing, and real use without falling off.
