It includes a fully built ATS Allison 1000 with top-tier billet internals, delivering strength and durability far beyond what the factory transmission could ever handle. You’ll also retain all your factory functions like tow-haul, tap shift, push-button start, and cruise control thanks to the included Translator module. Installation is straightforward and doesn’t require any cutting or block modifications. If you’re looking for a long-term solution that drives like stock but handles like a race-ready setup, this kit checks every box.

Complete Conversion With Heavy Duty Billet Performance

The ATS 319-954-2392 Stage 5 Conversion Kit offers the most advanced Allison swap available for 2013–2014 RAM 2500 and 3500 4WD trucks with the 6.7L Cummins. At the core of this setup is an ATS-built Allison 1000 transmission packed with serious hardware upgrades, including billet input, intermediate, and output shafts, a billet P2 carrier, C2 hub, and a modified P1 sun gear. These enhancements are engineered to withstand high torque loads and aggressive use without compromising shift quality or drivability. The package also features a deep transmission pan for added cooling and fluid capacity, ensuring long-lasting performance under load. The included ATS Translator module bridges the communication between the Allison TCM and your Ram’s ECM and BCM, maintaining all electronic features like factory shift displays, range select, remote start, and 4WD operation. Everything bolts in cleanly using the custom-cast bellhousing and adapter components, with no need for engine modifications. This is a full bolt-on solution built to eliminate the weaknesses of the 68RFE and deliver the strength and control that Cummins owners demand.
