Description
Ultimate Allison Conversion Solution. The ATS Diesel Performance Full Allison Transmission Conversion Kit is a Stage 3 upgrade that replaces the problematic factory 68RFE with the proven durability of an Allison LCT1000 6-speed. Specifically engineered for 6.7L Cummins-powered RAM 2500s, this kit ensures high-torque handling, increased longevity, and improved transmission performance for towing, hauling, or performance builds.
Construction and Appearance. This complete conversion system includes an ATS-built Allison LCT1000 with a deep pan, billet input and intermediate shafts, and an exclusive patent-pending bellhousing for seamless fitment to the Cummins block. The included TRANSLator CAN-bridge module enables full communication between the Allison TCM and the RAM ECM, allowing all OEM features—like tow/haul mode, push-button start, and electronic range select—to remain fully functional. It's built to endure the extreme demands of modified diesel engines and heavy-duty use.
Installation. Installation is rated as hard and is best handled by experienced professionals. While the kit is nearly plug-and-play, it requires full removal of the factory 68RFE, along with mechanical and electronic integration using the provided hardware and software.
Application. This ATS Diesel Performance Full Allison Transmission Conversion Kit fits 2015-2018 4WD 6.7L RAM 2500 w/ 68RFE Transmission.
