Features:
If you're putting serious power through your 2011–2016 Duramax and want a transmission that won’t flinch, the ATS Stage 5 Allison LCT1000 Crate Transmission is the upgrade your build needs. This isn’t just a replacement, this is a complete overhaul of how your drivetrain performs. With a heavy-duty torque converter, billet internals, and a deep transmission pan for better cooling, this system is designed to take punishment and come back for more. Whether you're towing heavy, racing at the track, or pushing the limits with a tuned setup, you’ll appreciate the crisp shifts and durability this transmission delivers. It’s the kind of peace of mind you want when every pound of torque matters. The ATS Co-Pilot controller gives you the precision and control to match that performance, making your shifts smarter and more responsive. If your build is all about putting big power to the ground reliably, this package checks every box.
The ATS 309-852-4362 Stage 5 Allison LCT1000 Crate Transmission is engineered specifically for 2WD GM Silverado and Sierra 2500HD/3500HD trucks with the 6.6L LML Duramax from 2011 to 2016. This crate package includes a fully built performance transmission, ATS’s Five Star torque converter, deep transmission pan, and Co-Pilot transmission controller, all working in sync to increase durability and drivability. Internally, it’s fitted with billet input and intermediate shafts for maximum strength under heavy load, along with a billet P2 carrier and C2 hub supported by a modified P1 sun gear. These upgrades are key for holding higher horsepower and torque levels, especially in towing and racing conditions. The deep pan enhances fluid capacity and helps manage transmission temperatures over extended periods. The Co-Pilot transmission controller brings added intelligence to shift control, helping reduce clutch wear while improving responsiveness. This system is purpose-built to outperform the factory transmission and is ideal for anyone pushing their Duramax beyond stock limitations.
