Built To Outlast And Outperform The 68RFE

The ATS Stage 3 Full Allison Conversion Kit delivers a durable and fully integrated solution for replacing the 68RFE in 2013-2014 RAM 2500 and 3500 4WD trucks. At the core is a fully built Allison 1000 transmission featuring billet input and intermediate shafts, designed to withstand the torque output of the 6.7L Cummins.

Every connection is designed to retain factory routing, including the fuel line brackets, shifter, and electronic control systems. With the included Translator module, your Allison transmission communicates flawlessly with the ECM and BCM, keeping all factory functions like cruise control, tap shift, and tow/haul operational. The result is an OEM-like driving experience with far superior durability and longevity. This kit is ideal for truck owners who want a strong, reliable setup that looks and functions like it came from the factory.
