47RE Valve Bodies

The factory valve body is one of the 47RE's known weak points, and is prone to cross-leaks and failures that can cause low line pressures, weird transmission function, and even parts failures in extreme cases. Tier One's 47RE performance valve bodies fix common issues with the stock valve body so that your Ram 2500 or 3500 truck can handle more power than stock while getting a vastly improved shifting feel and better reliability. Our high-pressure 47RE valve bodies turn up the line pressure and feature improved metal transducers and governors that fix some of the key failure points on the factory 47RE valve bodies. We even offer full-manual valve bodies (FMBV) for the 47RE transmission that can be paired with a manual shifter to give you total control over how your truck shifts, which is great for drag strip or sled pull use.
