48RE Complete Transmissions

Whether your own stock 48RE transmission has failed completely or if it's on the way out, grabbing an entirely new transmission that can handle huge levels of power and aggressive applications. Tier One's selection of built 48RE transmissions are specifically designed to handle all the power your Ram 2500 or 3500 can throw down. These transmissions are outfitted with a ton of performance upgrades that make them far more reliable than your stock 48RE transmission when you're towing heavy, ripping around off-road, or when you're tearing it up at the track. Tier One's complete 48RE transmissions can handle more power than stock, with some of our 48REs being able to hold over 1000 horsepower for high-powered diesel drag racing builds. All of these transmissions are 100% complete and install right into place of your truck's factory transmission with practically no hassles.
