ATS Transmission Package for Chevy/GMC (2010.5-16) 2500/3500 Allison LCT1000 6-Speed 4X4 LML Duramax, Stage 1 (with PTO)

The Allison 1000 has proven itself to be a stout unit behind the formidable Duramax powerplant. 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 percent 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.
