Unleash The Strongest Transmission Upgrade For Your Cummins

If you’ve ever wanted your truck to feel like it can take on anything, the ATS Stage 5 Allison Conversion Kit brings that confidence to life. This setup is built for owners who push their Cummins hard and want a transmission that never flinches under load. The shift quality feels tight and controlled, which makes towing or daily driving feel far more predictable. You can hook up a heavy trailer, roll into the throttle, and the Allison will hold firm thanks to the billet shafts and reinforced internals. The integration is smooth, so the truck keeps all its factory functions like tow‑haul mode, tap shift, and push button start. Everything bolts in cleanly, and the overall driving experience becomes more responsive and enjoyable. It’s the kind of upgrade you can feel instantly, especially when you put the truck under real‑world pressure.

Engineered Strength That Handles Serious Cummins Torque

This Stage 5 system brings a fully built Allison transmission paired with a billet input shaft, billet intermediate shaft, billet output shaft, and upgraded P2 carrier to handle extreme torque loads. The kit includes ATS’s patent‑pending Cummins‑to‑Allison bellhousing, which creates a perfect mechanical fit without any custom fabrication. Their TRANSLator module bridges communication between the Allison TCM and the Ram ECM so all factory features continue to function properly. The hardware package includes deep pans, adapter components, electronics, and everything required for a clean installation behind your 2015‑2018 Cummins. This upgraded Allison unit provides stronger gearsets and improved clutch capacity compared to the weak internal design of the factory 68RFE. Calibration updates ensure proper shift timing and functionality once the transmission is installed. With all components working together, the system delivers smooth shifts, consistent line pressure, and the durability needed for heavy towing or hard‑use driving.
