• Includes deep transmission pan, billet input shaft, billet intermediate shaft, and billet output shaft

• ATS-exclusive Cummins-to-Allison bellhousing—no engine block modification required

• Plug-and-play TRANSLator module ensures full factory feature retention (Tow/Haul, TapShift, Push Start, etc.)

Performance Benefits:

This Stage 4 kit is the most comprehensive Allison swap available for late-model RAM trucks. It addresses the key failure points of the Aisin AS69RC transmission with robust billet upgrades across the input, intermediate, and output shafts—essential for towing, tuned trucks, or high-horsepower builds.

Thanks to the included TRANSLator control module, your truck maintains all OEM functions including cruise control, push-button start, tow/haul mode, TapShift, and 4x4 Low range (if equipped). Installation is straightforward with minimal fabrication required.
