Ready Your LBZ for Real-World Power and Performance

If you’re starting to push your 2006–2007 Duramax-powered Silverado or Sierra 2500HD or 3500HD harder than the stock transmission can handle, the ATS Stage 2 Allison LCT1000 Crate Transmission is the upgrade built to keep up. This package is designed specifically for 4WD trucks and comes complete with ATS’s fully reinforced performance transmission. It’s paired with the ATS Five Star torque converter, engineered to deliver smooth power transfer and improved low-speed drivability. Also included is ATS’s deep transmission pan, which increases fluid capacity to help keep temperatures down when you’re towing, hauling, or putting extra power to the ground. Together, these components give you the strength and cooling you need to work your truck harder and drive it with more confidence.

Enhanced Control with the ATS Co-Pilot Controller

Taking this package even further, ATS includes its Co-Pilot Transmission Controller to give you better control over shift points and torque converter lock-up. This added control helps improve drivability, protect internal components, and make the most of your truck’s power whether you’re on the highway or off the beaten path. The entire package is designed to bolt right into your LBZ-powered truck without modification, making it an ideal choice for serious builders, heavy haulers, or anyone looking to avoid the common weak points of the stock transmission. Just keep in mind that a $500 freight shipping charge applies at checkout, but the peace of mind and performance gains are well worth it.
