This Is The Swap Your Cummins Has Been Waiting For

The ATS Stage 2 Full Allison Conversion Kit is designed to give your 2015-2018 RAM 2500 or 3500 2WD the transmission it truly deserves. This kit drops in a fully built Allison 1000 with a billet input shaft, a deep transmission pan, and everything you need to make it feel like it came that way from the factory. You keep all your original functions like push-button start, tow/haul mode, and range selection. Best of all, it’s nearly plug-and-play, no cutting or strange wiring tricks required. This kit isn’t just about brute strength, it’s about driving confidence, whether you're towing heavy or just cruising with added peace of mind. If you're tired of second-guessing your stock transmission every time you hit the throttle, this swap is your answer.

Factory Integration Meets Proven Allison Reliability

The ATS Stage 2 Allison Conversion Kit blends durability with technology to deliver a seamless driving experience. It includes a custom bellhousing that allows the Allison LCT1000 to bolt directly to the Cummins without fabrication. A billet input shaft and deep pan boost torque capacity and cooling, key for trucks running heavier loads or added power. The real magic comes from ATS’s TRANSLator module, which allows the Allison transmission to communicate with the RAM’s ECM and BCM like a native system. This means cruise control, tow/haul, and electronic range selection all continue to work flawlessly. No need to replace your shifter or modify the engine, everything fits where it should. This kit is engineered to take the guesswork out of swapping transmissions, giving you both reliability and refined integration with your existing systems.
