Performance Benefits

The ATS Stage 2 Full Allison Conversion Kit is the ideal upgrade for RAM Cummins owners who demand more from their truck’s transmission. It eliminates the weaknesses of the stock 68RFE by replacing it with a professionally built Allison 1000 transmission, designed to handle greater torque loads, especially under heavy towing or tuned power applications.

With a billet input shaft, high-capacity clutch packs, and proprietary controller integration, this system ensures consistent, smooth shifting without the common failures of factory designs. The included TRANSLator module maintains full OEM integration, allowing for a seamless transition with all dash and drivetrain functionality preserved.
