This complete swap replaces the weak factory transmission in your 2015-2018 RAM 2500 or 3500 with a proven Allison LCT1000 setup that’s been reengineered by ATS to handle real-world torque and abuse. Whether you're towing a heavy trailer through the mountains or just looking for smoother shifts and better reliability, this conversion delivers on every front. The Stage 2 kit includes a fully built Allison transmission with a billet input shaft and deep transmission pan for improved strength and cooling. What sets this package apart is how seamlessly it works with your truck. Thanks to ATS’s TRANSLator module and patent-pending bellhousing, you retain all your factory controls, from tow haul mode to push-button start. You won’t lose cruise control, tap shift, or your factory dash readouts. This is more than a transmission swap, it's a performance-minded upgrade that transforms your driving experience.

Built For The Torque Your Cummins Demands

The Stage 2 Full Allison Conversion Kit from ATS is engineered for serious 6.7L Cummins power and long-haul performance. It replaces the factory 68RFE in 2015-2018 RAM 2500 and 3500 4WD models with a professionally built Allison LCT1000 transmission, complete with billet input shaft and deep pan for added fluid capacity and cooling efficiency. The system’s backbone is ATS’s proprietary TRANSLator module, which bridges communication between the Allison TCM and the truck’s ECM and BCM. This ensures all factory features like electronic range select, transfer case control, and tow haul mode continue to work flawlessly. The included bellhousing is cast specifically for the Cummins, eliminating the need for custom fabrication or engine block modifications. The conversion kit also supports tuning flexibility, with the ability to reflash the truck to an AS68RC or AS69RC calibration for compatibility. Every component is designed to handle the torque load of a modified or heavily worked Cummins, making this a solution that’s as durable as it is integrated.
