You Will Feel The Difference Every Time You Drive

If you’re tired of babying your factory transmission just to keep it alive, the ATS Stage 1 Allison Conversion Kit might be the upgrade your Cummins has been waiting for. Whether you're hauling heavy loads across long distances or running a high-horsepower setup, this conversion gives you the confidence to push your truck without worrying about what’s happening under the floorboards. This is not just a replacement, it's a transformation that brings next-level durability, smoother shifts, and the kind of reliability that gives you peace of mind in any driving situation. You get a fully built Allison 6-speed automatic designed specifically to handle the torque that a 6.7L Cummins can throw at it. All the original factory features like cruise control, tow/haul mode, push-button start, and even tap shifting remain fully functional thanks to ATS' proprietary TRANSLator module. The install is clean, the fitment is spot on, and there’s no weird compromise that leaves you missing your old setup. It’s a smart move for anyone looking to finally match their transmission to the true potential of their engine. If you're building for the long haul, this is the kind of upgrade you’ll never regret.

Precision Engineered To Fit Perform And Outlast

Behind the scenes, this conversion is loaded with carefully engineered components designed to work together in harmony. ATS includes a purpose-built cast bellhousing and extension housing that allows the Allison to bolt directly to the Cummins engine without needing to grind or modify anything on the block. The TRANSLator module bridges the communication gap between the Ram’s factory computer systems and the Allison TCM, keeping all your electronics working exactly as they should. The included billet five-star torque converter and deep transmission pan offer stronger lockup, increased fluid capacity, and better cooling performance. The entire package is engineered to handle more torque than the 68RFE ever could, thanks to larger clutch packs, beefier gear sets, and a stronger case design. You also get a full hardware kit including cooler lines, wiring harness, transmission mount, and even the dipstick tube for a near plug-and-play installation. ATS has taken all the guesswork out of this swap, delivering a complete solution that transforms your drivetrain with OEM-style fitment and long-term durability. Whether you're chasing performance or longevity, this kit is built to exceed both expectations.
