Give Your LB7 the Strength It Deserves

If your 2001–2002 Silverado or Sierra 2500HD/3500HD with the 6.6L LB7 Duramax is still relying on the factory transmission, chances are it’s starting to feel the strain of towing, hauling, or running added power. The ATS Stage 2 Allison LCT1000 Crate Transmission Package is built to help your truck handle the load with confidence. Specifically designed for PTO-equipped 2WD models, this package features ATS’s fully rebuilt performance transmission, backed by their Five Star torque converter for improved power delivery and smoother shifts. You also get an ATS deep transmission pan that increases fluid capacity to reduce heat buildup, helping your transmission perform better under heavy workloads or long hauls.

Added Control and Durability with ATS Co-Pilot

What really makes this package stand out is the addition of the ATS Co-Pilot Transmission Controller. This controller manages shift timing and torque converter lock-up to improve drivability and protect your transmission from unnecessary stress. It’s designed to work seamlessly with the included upgrades, giving you a complete, ready-to-install solution for trucks that see serious use. Whether you’re pulling equipment to the job site or just want more peace of mind on the highway, this transmission package delivers reliable performance mile after mile. Don’t forget to factor in the $500 freight charge at checkout, but the confidence you’ll gain in your drivetrain is well worth the investment.
