ATS Diesel Performance Stage 1 Transmission Packages 309-914-2116

This is an ATS Diesel Performance Stage 1 automatic transmission package, a remanufactured 4-speed unit built on a Cummins bellhousing bolt pattern with a torque converter included. The case is aluminum with a black finish, and the deep pan is aluminum finished in black as well.

What's included and what isn't

The torque converter ships with the unit, and it's built to work with a lockup setup, but the package does not include a flexplate, transmission controller, wiring harness, cooler, trans-brake, transmission fluid, or dipstick, so plan for those separately depending on your install. The valve body uses a standard automatic design with a standard shift pattern rather than a performance shift kit layout.

Before you order

Confirm your truck's bellhousing matches the Cummins pattern here before buying, since this is built around that specific bolt pattern rather than a universal fit. The steel input shaft and deep aluminum pan are part of the Stage 1 package spec, and the unit is sold as a complete kit rather than individual components, remanufactured rather than built from entirely new parts.
