Bring Your LB7’s Transmission Back to Life

Your early LB7 Duramax might have some miles on it, but that doesn’t mean it’s done working. If your 2001-2002 Silverado or Sierra 2500HD or 3500HD has been showing signs of transmission wear—or if you’ve already added more power than the stock unit can handle—ATS has the perfect solution. The Stage 4 Allison LCT1000 Crate Transmission is designed to restore strength and reliability while giving you the performance headroom you need for towing, hauling, or tuning. This isn’t just a repair; it’s a serious upgrade that makes your truck feel capable and dependable again.

Built Stronger to Keep You Moving

This complete package comes with a lineup of proven ATS upgrades that work together to handle real-world demands. It features the ATS Five Star torque converter to help transfer power more efficiently, especially under load. The deep transmission pan keeps fluid cooler and increases capacity for better long-term durability. With the included ATS Co-Pilot controller, you gain better control over shifting and line pressure, helping protect your transmission when you’re working the truck hard. Billet input and intermediate shafts add the kind of strength your drivetrain needs to stand up to added stress. Designed specifically for 2WD LB7 models, this package ships ready to install. Keep in mind, a $500 shipping surcharge will be added at checkout to cover freight delivery to your location.
