Product Description

Strengthen Your 618 Transmission for Towing, Work, and Daily Driving

The ATS 309-914-2116 618 Stage 1 Package is built for 1990-1993 Dodge 4WD diesel trucks equipped with the 5.9L Cummins and 618 automatic transmission. ATS designed this package to address factory transmission weaknesses by improving clutch holding power, line pressure, fluid control, and overall shift quality.

For early Dodge Cummins trucks, the 618 transmission is often one of the first weak links when the truck is used for towing, hauling, or performance upgrades. This ATS Stage 1 package adds proven internal upgrades that help your transmission hold power more effectively while improving firmness and long-term reliability.

Whether you are restoring dependable operation in your first-gen Cummins or upgrading for heavier workloads, this kit delivers the core transmission improvements needed to support the way these trucks are actually used.
