1998.5-2002 Ram 5.9L Cummins Valve Bodies

The factory valve body on your 5.9L Cummins Ram's 47RE transmission is not known for its reliability at stock power levels, much less when you throw some extra power or heavy towing into the mix. Tier One's performance valve bodies for 1998.5-2002 Ram 5.9L Cummins trucks offer higher line pressures and a ton of reliability improvements so that you can add aggressive tuning, bigger turbos, oversized injectors, or exhaust upgrades without your valve body letting you or your truck down. We even offer full-manual valve bodies that can be paired with a manual shifter to give you full control over your Ram's transmission function for aggressive street driving or use down at the drag strip. If your transmission clutches are already burnt out from low pressure, a new valve body won't bring them back, and you may be better suited getting a fresh start with one of our 1998.5-2002 Ram 5.9L Cummins Complete Transmissions. A high-pressure valve body provides the holding power you need, but you need a converter that can handle that lock-up force without warping, so pair your valve body with one of our 1998.5-2002 Ram 5.9L Cummins Torque Converters. Improved fluid flow helps reliability, but towing heavy loads still generates massive heat, so keep your fluid cool and your new valve body solenoids happy with our 1998.5-2002 Ram 5.9L Cummins Transmission Coolers. When installing a new valve body, it's the perfect time to upgrade your fluid capacity or replace internal filters, so you can find deep pans, filters, and other essential components in our 1998.5-2002 Ram 5.9L Cummins Transmission Parts.
