Designed For Strength Tuned For Precision

This Stage 3 ATS Allison Conversion Kit comes loaded with heavy duty internals and smart integration to ensure your truck performs flawlessly under pressure. Built around ATS’s fully re-engineered Allison 1000 transmission, this kit includes a billet input shaft and billet intermediate shaft to handle the high torque demands of the 6.7L Cummins. The deep transmission pan keeps temperatures down while adding fluid capacity, improving cooling during long hauls and heavy use. ATS’s patent-pending bellhousing ensures proper alignment with no extra fabrication needed. The TRANSLator module bridges communication between the Ram ECM and the Allison TCM, which means your dash, shifter, cruise control, tow-haul mode, and more all continue to work exactly as they should. This makes the swap nearly plug-and-play with minimal calibration. It’s a technically sound solution for drivers who need a transmission that doesn’t flinch under load and offers dependable performance for years to come.
