48RE Valve Bodies

The stock valve body in your Ram's 48RE transmission is a common failure point and is known for suffering from cross-leaks, warpage, and low line pressures when you start to push your Ram hard. Tier One's high-pressure 48RE valve bodies have higher line pressures than stock and revised internal designs that make them far more reliable than stock, all while improving both shifting and transmission lubrication to maximized reliability and performance, especially if your Ram is throwing down more power or towing heavy. We even offer 48RE full manual valve bodies (FMVB) that allow you to run a manual shifter to give you even more control over the operation of your Ram's 48RE transmission. These valve bodies drop right into place of the stock valve body, and are an excellent way to prep your truck for big-time power. Also check out our 48RE torque converters or our 48RE input shafts.
