Take Your Cummins To The Next Level With An Allison Upgrade

If you’ve ever wished your truck felt stronger, smoother, and more confident under load, this kit gives you exactly that by letting you ditch the 68RFE and step into the strength of an Allison. The install kit is built for owners who want reliability without losing the factory feel of their truck, and it makes that possible with a setup that keeps features like push button start and tow haul mode working as they should. Everything fits cleanly, so you are not stuck fabricating brackets or modifying the engine just to make things line up. The system blends into your truck naturally, leaving you with a setup that feels like it came this way from the showroom. With the right Allison transmission, your Cummins can finally handle the power and the workload you throw at it without feeling stressed. Daily driving becomes more consistent and towing becomes more controlled, which is exactly what most owners want out of a transmission swap. It is a dependable way to give your truck the backbone it deserves.

Built For True Integration Between Cummins Power And Allison Strength

This kit uses ATS Translator technology to let the Allison TCM and the Ram ECM communicate properly, which is the key to keeping all factory functions operating as intended. The patent pending bellhousing provides a precise mechanical connection between the Cummins engine and the Allison transmission, eliminating the need for custom fabrication or modified mounting points. Every component in the kit is designed to match factory routing and factory wiring locations, allowing the install to stay clean and predictable. The system supports full electronic range select, tow haul mode, and proper transfer case communication so the truck behaves exactly as the electronics expect. Cooler line adapters, brackets, mounts, and wiring are all included, ensuring the Allison sits in the chassis with the correct angles and clearances. This design prevents common calibration or communication issues that occur with incomplete swap kits. The end result is a fully integrated transmission conversion that blends OEM functionality with the durability Allison transmissions are known for.
