Take Your Duramax to the Next Level with Proven Transmission Strength

If you’ve pushed your LBZ-powered 2WD truck to the point where your stock transmission just can’t keep up, the ATS Stage 2 Allison LCT1000 Crate Transmission package is the upgrade that delivers the strength and reliability you need. Specifically designed for 2006-2007 Silverado and Sierra 2500HD and 3500HD models with PTO-equipped 2WD drivetrains, this complete package gives your truck the ability to handle heavier loads, bigger power, and long hauls without hesitation. ATS starts with their performance-built LCT1000 transmission, engineered to take on the demands of towing, worksite duties, or performance builds that push well beyond factory specs.

Complete Package with Converter, Deep Pan, and Co-Pilot Control

This transmission package isn’t just about raw strength—it’s built to work smarter, too. Included in the kit is the ATS Five Star torque converter, designed to improve torque transfer and reduce slip under load, giving you better acceleration and towing control. You also get the ATS deep transmission pan, which increases fluid capacity to help manage heat, especially when you’re working your truck hard. To top it off, the ATS Co-Pilot transmission controller fine-tunes shift performance and line pressure, helping you put all that power to the ground smoothly and reliably. Whether you’re building a heavy hauler or simply want peace of mind on the highway, this package delivers. Please note, a $500 shipping surcharge will be added at checkout.

Fits: 2006, 2007 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LBZ PTO 2WD
