GM Transmissions


The Allison 1000 has proven itself to be a stout unit behind the formidable Duramax power plant. However, as power is increased over stock, weak points quickly rise to the surface. ATS addresses the inherent short-comings to offer a robust setup for your modified LML. By increasing the capability of the torque converter, clutch surface area and line pressure, the transmission can hold 200% more torque than stock. The result is a setup strong enough to handle aftermarket fueling, turbo(s), tuning and the intensity of drag racing, sled-pulling or dyno competitions. Yet, it is still smooth enough to tow and daily drive.

As with all ATS transmission packages, the transmission is covered by a 5 year/500,000 mile warranty.
